Eutelsat 8 West A

iba

I picked up this sat on Saturday on a small Lidl dish (dont know the exact size) - didnt think it was possible. But I cant get 9/10 or 7.

Yeah, I can get the 11054H tp with one of the 35cm camping dishes.

This satellite has a European beam, you can't compare reception to 7 west. Also, there aren't any satellites at 9 or 10 degrees west that I'm aware of, you must be referring to 9 & 10 east?

Yes it was the 11054H Transponder - picked up 7 stations or so.

Why cant compare to 7 West - is it because this 8 has a European Beam and 7 does not?

Yes I mean 9 and 10 East.

Everything on 7/7.3 degrees west is aimed at Middle East & North Africa. I can't get anything with a 1.1m dish where I am, but you might have more luck further south.

On my Multi set-up, I picked up 2 stations on 7 namely TRT Cocuk and TRT Anadolou - thats on a 1.1m dish in Dublin

Peter Rhea

Those channels are on 7 east, not 7 west.

What exactly is the purpose of this thread?

Yep 7E (sorry)

Just I couldn't understand how I can pick up 8 west - I didn't think it was possible.

Iba, Just to point out that unless you move your prime focus from 26e to 7e...
Its not really accurate to say you can only receive 2 channels on a 1.1mtr dish.
As it stands your dish is aimed at 26e, correct?
Trying to get 7e on this set up means you are at a 19degree offset trying to receive an already weak bird your 1.1mtr dish at that much of an offset will perform more as a 40-50cm dish if even that well...
Which isn't big enough to pull anything but the very strongest TPs on those bird.
If I recall earlier you had similar issues with 16e and with 39e.
This is caused by the reflector performance dropping off at offsets over 10degrees on marginal strength sats.

What you have to remember is that the further the satellite is offset from your prime focus, the lower the actual performance of your dish.
As a rough rule of thumb if prime focus is 100% performance on a 1.1mtr dish, 5degrees either side will be 90% performance or equivalent to @90cm dish, 10 degrees either side will be @60%performance or 55-65cm dish equivalent.
It is important to plan your LNB placement with these performance drops in mind.
There is a thread by Zardoz(I think) which gives good roll off figures for a variety of dish types.

The important thing to remember is that in a multiLNB your dish will perform to its best @10-12degrees either side of prime focus any reception so pointed at 26e your realistic range of Sats is from 13e to 39e and at that much of an offset 39 is going to be very marginal.
Anything outside of that window is a bonus and on weaker sats is impossible.


Unless you either
A: Change your prime focus to 16e or maybe 19.2e you will not receive more than the very strongest tps from 4.8,7e, 9/10e and it will be the same on your earlier quest for 39e...
With 26e as your prime those sats will require you to change your prime(and likely lose 26e reception in the process) or
B: Pick a new set up, either a 1.5mtr+ Offset, A motorized dish or mayhaps a toroidal setup.

Hi Banie,

Thanks for all that very informative information.

Yes my prime is 26 - and I like it for MBC and the other Arabic stations and now that Al - Jazeera have the footie next year (and a friend of mine in Algeria who seems to know his stuff reckons Al _ Jazeera will also broadcast it via IPTV). But sorry, I degress.

You are right, with 16, I only get 7 FTA stations and I cant get 39 at all (nor 36 or 33) and I cant get 9/10 either.

STB has told me before that if I got 39 I wouldnt be able to get 13 because of all the reasons you have pointed out above. So I was going to do sats from 39 down to 19 keeping 26 as prime. And then put up my spare Lidl dish just for Hotbird.

A 1.5m dish is an interesting idea, have to have a think about that or the Torodial (but thats not exactly cheap). Dont want a Motor one though.

Will see if I can find that zardoz thread in a while.

Thanks again for all the info

Iba, you do realise it doesnt matter how you align the LNBs on your current setup, if you keep 26e as your prime focus you will not receive 39e consistently?

Its not just a case of dropping 13e from your current setup and recentering your multibar to allow a bigger offset on the 39e side of the bar.
Because even at that at 13degree offset on a 1.1mtr dish the drop off in reflector efficiency means your 1.1mtr dish with prime focus at 26e is acting as @50cm(probably even less) dish at the offset needed for 39e reception.
This is the same reason you were only receiving 7 channels on 16e when you tried that.
You tried 16e at a 10 degree offset, so the offset LNB acted as if it was an a sub 60cm dish.

Just to contrast, I have 16e as my prime on an 88cm dish and I pull in @550 tv services(I get every channel I've ever tested on that bird) and probably more,
on 9\10e I pull in @340 tv services at a 7degree offset
on 4.8e @200 tv services at an 11degree offset (most useless though no Nordic beam! haha!)
on 23.5e @300+ tv services at a 7.5degree offset(just a quick note, I am not counting data\radio on those estimates)
Along with receiving the full suite of channels available at 13e, 19.2e and 28.2e.

The most important factor in a MultiLNB setup is planning what you want in the 1st place.
You need to match what you want, and what you need to what your dish can do.
Use a site like http://satbeams.com/footprints to get the recommended dish sizes for the birds you want to receive and plan your setup with those numbers in mind.
Its very handy for selecting a sat, clicking your location on the map and seeing what the minimum recommended dish size is.
I also found the graph's I mentioned earlier, just a quick caveat on the graphs...
They are based on readings from SE Europe but they give a good comparison of Dish performance across a range of Dishes and satellites from a fixed location.

Still don't get what his OP is about. What has picking up the European beam from 8 west got to do with the satellites at 7, 9 & 10 degrees east?

What reason is there to think those channels on 8 west can't be received in Ireland?

banie01

I think he maybe got 8w mixed up with 7w which is notoriously difficult to pick up.
As for what 8w has to do with 7e and 9/10e, well I'm sure Iba can explain that one.

STB

In my experience optimising 26E messes up everthing else on the 20+ degree Triax Multibracket (the degree spread differs depending on Dish size - on a smaller dish the lnbs will be closer together on the bracket).

I now have 28E,26E,23E, 19E and 13E. The dish elevation is at 25 on a TD88. 9E/10E is far too weak. This is due to the elevation I am using for the most focussed point required for 26E. My dish is pointing at perhaps 25E.

So it is true that 26E at prime (or near prime)focus will mess up your chance to get 7E/9E/10E 4.8E. The dish elevation really needs to be at 29/30 for these to come in properly on the multibracket. At which stage 26E is out.

Hi Banie,

Thanks again for all that. Been reading through all those threads and checking out that satbeams website all morning. Cant say I understand everything but I am trying.

It seems that to get Sat 39 I need a 50cm dish but I couldnt get it on the little lidl dish I was playing with at the weekend so Ill measure it later to see what size it is.

Regarding the T-90, from what I understand/reading, it is not any good for picking up Sat 26.

So my probable new plan is to get the Triax 88cm dish and copy STB's set-up where he has 13, 19, 23, 28 and 39 and just leave the 1.1m dish just for 26.

Because I did not understand this East and West thing. I thought here in Ireland we could only pick up Sats which had East. So therefore I did not understand how could I pick up this 8 West Sat when I couldn't even pick up 7 and 9/10 East.

Congratulations - but does this mean you have got rid of 39?

I see you have 23 there aswell, I cant get that - are you using a skinny LNB?

My elevation is similar - Im at 25.5

Yes 26 is so so sensitive, when I tighten the bolts at the back of the dish, even half a turn can lose the signal.

P.S. you got a new pic?

Yes I got rid of 39E but only short term (I left my drill in Dublin so couldnt redrill the bracket).

I am using a Skinny LNB at 26E. I will post a pic later.

You have a 110cm dish so you should have no problem picking up 23.5. The spacing is wider on such size dish. The tilt of the bracket should be increased to full tilt (by drilling in the bottom rung).

Im nearly sure that everything that I read before stated that one couldnt get 26 on an 88 dish - so its great that you have got it - and the signal is good I take it using the skinny at 26.

Ok, Im not doing anything else until I see your latest set-up except ordering this:

http://www.amazon.co.uk/Inverto-IDLB-TWNL20-MULTI-OPP-0-2dB-Black-MultiConnect/dp/B001T1QANU/ref=sr_1_1?ie=UTF8&qid=1365516783&sr=8-1&keywords=Inverto+IDLB-TWNL20-MULTI-OPP+Twin+LNB%2C+23mm%2C+0.2dB+Black+MultiConnect

BTW - I got those Compression f Connectors you advised me about from Hong Kong

STB

Okay well this is my latest setup. Its interchangeable by sliding the bracket east or west.

19E 23E //26E 28E 39E



OR

13E 19E 23E //26E 28E

You may find that you have to tightly wrap some masking tape on the outside cable at the top, fold the braid down to get them tight. They are made for wider cables.

btw yes its a Inverto Black Multiconnect. A tenner from yuchason on ebay.

iba

STB, thats brillant. At least we know now that it is possible. So if I cant get 39 the reason is because of line of sight.

Thanks for the tip about masking tape - I thought I was doing it wrong coz they were not gripping very tight.

You might well be the 1st person in Ireland to get 26 on the 88 dish too - enjoy MBC (and Dubai 1 also has English movies)

I need a Twin, the cheapest I could find was that one I posted earlier on Amazon

I spoke to Yuchanson earlier on on the phone asking him if he had the twin but he didnt. He asked me what I was trying to do and I told him and he suggested a monoblock LNB and then I did some googling and found this which I thought was interesting:

http://en.wikipedia.org/wiki/Duo_LNB

But do you think a monoblock could work for 23.5 and 26 or 25 and 28?

snaps

A monoblock is no good, it has an internal diseqc switch so as far as i know you wont be able to use another diseqc switch with it? Its only good for say 13/19 or 19/23 whatever its designed for and not to be used in conjunction with other lnbs on a multi lnb feed dish.

No monoblock will not work with your 8 diseqc switch AFAIK.

The reason you cannot get 39E is (assuming you have drilled on the bottom rung of the bracket for the extra tilt) because its running off the bracket. You are using a 110cm dish, so the spacing on the bracket is wider, hence you run out of space. Since my bracket is concentrating on a TD88 the LNBs are bang smack up against each other.

You need to extend off the existing bracket with one of these.



I suggest you keep your dish centred where it is. Take the bracket off. Redrill it so that 3 quarters is on the right (looking at it from the dish face). Then add the bracket above to the last lnb on the most left (probably your 23 or 19). This will extend the bracket sweep for your 110.

iba

This is great, really getting places now.

This is the right one, yeah?

So if I understand right would the LNBs for 19, 23.5 and 26 go into this/the above?

And do I also still need the skiiny Lnb?

The LNB for 19 or 23 (I am guessing the furthest left will be 23 if the right hand side is up at 39 on the Triax multibracket on a 110cm).

So you will have 23 lnb on the Triax multibracket but also connected to the lnb holder above which will extend the length of your bracket. It might be flimsy but you dont know until you try.

Remember you dont need to move the dish. Just take the bracket off and redrill it on the three quarter left in the bottom rung like I have except a little further to the left).

I dont think slim lnb's will be of any help. The only reason I need one is because of the spacing on a TD88 between 26 and 28 which are bang smack up against each other. I saw the gap on your 110cm between 28 and 26. You are achieving that with normal LNBs so the slims may not be required.

That is a great set up that you have STB. I tried my Smart 125 CM dish the other day at about fourteen feet height off the ground and couldn't get anything from 26E. The bracket on the chimney is about three feet higher up but if it works I will have to wrap steel wire rope around the wall bracket and connect it to one of the old chimney lashings as it would come down in a storm methinks.
I am using an Inverto Black Ultra Quad. I Cannot understand why I haven't been successful in receiving it here yet. I may try again later today. Could it be interference/noise effecting the LNB? There is an old farmers building/ shed in that direction standing around twenty feet high

Where do you think the interference is coming from? The shed? How close is the shed & is it on higher ground? Don't forget your dish is already 14' above ground level.

Can you get a signal from 28 east?

The reason Im asking about the slim LNB is because Im not able to get 23 with any of the fat ones I have at the moment. I think the fat one I have at 26 is pushing/interfering with 23.

But I see a difference with your 26 positioning than mine.Remember I hacked sawed away some of the black plastic bracket in order to get LNB at 26 more flush with the arm. Ill move it back to the corner, the way you have it, and see if that allows me to get 23.

My dish is only 2 or 3 meters off the ground and 12 meters or so away from my double storey house and its facing the house.

26 is just so hard to tune in, so delicate. I would suggest locking in on 28 and then just moving ever so slightly to the right (with the dish behind you) to get 26, (presuming you just have one LNB connected). Put the transponder on 11919 and 27500 (This is MBC). My elevation is 25.5 and I think STB has said his is 26. On Dishpointer the suggested elevation for my dish was 22. So perhaps check dishpointer for your suggested elevation and then increase that by 3 or 4. But it is very delicate and even turning any of the nuts at the back of the dish half a turn can lose the signal in my experience.

You shouldn't use 'left' & 'right' without specifying if this is viewed from in front or behind the dish.

I use this tp on Badr 4: 12182 H, 16200, as this symbol rate isn't used on 28 east.

Hi, there's no problem getting a signal from 28 E about seven to eight feet off the ground from the side of the house.
The house is a few feet higher than where the foundation of the farm building is and it is approximately twenty three feet to twenty five feet away. The chimney would be slightly higher up than the side wall with the pole attached and ten feet at least further back than the side wall.
The old 80 CM Lidl dish which is on a wall bracket on the chimney was broken a couple of weeks as the wind burst the dish face around where the four screws attach the plastic back bracket turning the dish almost inside out. Metal epoxy resin will repair it though.
I will try again tomorrow to get 26 E weather permitting. The roof may be the best bet in receiving it, it could be that the elevation needs to be higher at around twenty five to twenty six degrees elevation for my dish.

Isn't 26 E to the left of 28 E anyway from the back of the dish?

The elevation angle will be the same for a given satellite position & location on Earth, no matter what you point at the satellites. The elevation scale on an offset dish will take the offset into account & the only other factors to consider are accuracy of the scale & verticality of the mounting.

26 degrees east is (very obviously) 2 degrees further west than 28 degrees east. It shouldn't be a big stretch to work out which way to turn the dish.

It says 22.1 degrees elevation on Lyngsat for my area but Iba in Blanch said that his is elevated a few degrees higher to get 26 E. The mounting is spot on on the chimney so I will try it there next.

That is a great set up that you have STB. I tried my Smart 125 CM dish the other day at about fourteen feet height off the ground and couldn't get anything from 26E. The bracket on the chimney is about three feet higher up but if it works I will have to wrap steel wire rope around the wall bracket and connect it to one of the old chimney lashings as it would come down in a storm methinks.
I am using an Inverto Black Ultra Quad. I Cannot understand why I haven't been successful in receiving it here yet. I may try again later today. Could it be interference/noise effecting the LNB? There is an old farmers building/ shed in that direction standing around twenty feet high

Height means nothing unless there are building immediately in the way. My dish is 5ft off the ground. This means I can tweak as I like.

You should have no problem getting 26E on a 125cm dish. I am receiving it with a TD88.

If you have your 125cm dish centred on 28.2, then standing behind the dish edge it ever so slightly to the right. Your dish elevation should be at 23 (for 26E) if you are not using a multibracket and have the lnb at main focus. (to clarify the reason my elevation is set at 25 is because I am using a multibracket with the 26E not at prime focus and am trying to pick up several satellites, which the multibracket compensates for elevation wise)

Having a pre-tuned box will help you find it. What type box do you use ?

I usually use the Comag Silvercrest SL65 to align dishes. I tried to upgrade the firmware a couple of times with an RS 232 cable as it crashes on a certain frequency at 19 E but there were no instructions anywhere or tutorials on how to go about doing it. I also have Grundig/ Goodmans/Bush Freesat PVRS and Ross HD receivers.

No, I have mini binoculars to see the 14" portable TV and receiver signal readings down below from the roof. Lashing today so couldn't try.

I tried earlier before dark and I could only get 23.5E, I couldn't tune in anything from Badr 4 yet. That other sat has an elevation of 23 degrees and not a sniff of the MBC channels or Dubai One. I will try the Samsung tuners in the Goodmans/Grundig Freesat box next. The elevation must be higher than 23 degrees here for Badr 4? There's no scale either on this stupid dish. :mad:

Well your very close, perserverance my friend. Now you have 23 and 28, you just have to keep moving it inbetween to get. Its very delicate but Im sure you will get it eventually.

Watching Blood Diamond on MBC2 now with 90% Signal Intensity and 70% Signal Quality.

BTW I used to have the SL65 and I could get Badr on that, so no need to rule out the box.

Dishpointer has it at just over 22 degrees for the Dublin area.

Whatever the true figure, it will be slightly higher elevation than for 28 east & slightly lower than for 23. If you can start from one of these, you don't really need the elevation scale.

When you do eventually hit on it, it will simply be that you have managed to develop the technique for aligning a moderately sized dish on a weak signal, nothing more, nothing less.

I'll try 11919 H 27500 again at 28.2E and nudge the edge of the dish to the right to see if I can lock on the MBC channels, I may have got it before a few times but when I scanned I got the no channels message when and the quality level was fluctuating from 63% to 70% at 11919. Would the skew angle of the LNB make a difference for 26E being received or not if it is that weak? It is a 2007 model I presume of SL65 sat receiver. I could get nothing on the Yemen transponder at all.
How far is 26E to the right of 28e, less than an inch or the full inch to the right?
I also have an old 90CM, Andrews Valueguard satellite dish which is very strong and heavy, maybe I will get a lock with that? At least it has a scale for elevation. Does anybody have a pretuned channel list for Badr4 at 26E for any satellite receiver? Ross HD receivers?

FREETV

Peter, were you trying to say that if I can get 28E on the dish then I won't have to change the elevation to get Badr 4 at 26E? I have been moving the dish back to the left in tiny increments after receiving 23E quite easily with over 80% signal quality but no lock on 26E. Is it the feckin' dish or is it me?

FREETV

Iba, did you ever align your dish with just one LNB for Badr 4 in the past and receive it or just with the multi sat set up?

When I align it I always use just one LNB

Anymore ideas please? My dish is bigger and I am frustrated. I wonder did it not always scan in the channels and give the no channels message using the SL65 and did the signal quality go from 63% TO 70% at the 11919 transponder frequency. Was the skew of the lnb important and the difference between receiving a picture or none? If only I had a pre tuned sat box for Badr 4.

What elevation reading was on your Triax TD 110 dish FOR 26E please? My 90 cm Andrews dish has an elevation scale, I may try it later as an 88cm dish received it in Wexford.

Theres not much skew on it at all - look at STB's pics a page or 2 back - the skinny LN is his 26.

Ive done it without a pretuned box so it is possible.

26 is just so delicate. As Ive mentioned before, just a twist of a nut at the back of the dish can make all the difference for me. I can understand your frustration, but all I can say is keep trying - you have 23 and you have 28 and now you have to just keep moving between those two.

Peter, Banie, STB all know a lot more than me, but maybe lock on 28 then just move an inch to the right with the dish at your back and do a full scan and see if that brings in anything and keep doing this ie keep moving the dish and keep doing a full scan.

I know its not very scientific but I dont know what else to say.

BTW are you in Dublin? If you are and if you want, you can bring your box out to me and we can scan in 26

11919 H, 27500 will show quality from the Astra 2A tp which is near the same centre frequency. At least if you use the Yemen tp, you'll know it isn't from 28 east.

You should have to increase elevation slightly.

swoofer

hi, is that dish damaged and did you post before. that 26 hits dish very high and its harder with a 125 than a 110cm.

and you should aim for the strongest transponder, i posted a few ages ago but cant recall. and if its windy dont even try. a good one as i type is 12015v 27500.

By about one degree, all I can do is lock on 28E, change the elevation, then use the Yemen tp again and turn the dish over and back very slightly. Oh, the joys.
