@iba, what sat cables did you use and those f connectors look like they are gold plated, and what dish elevation is used. It looks very good.

Hi GBCullen,

Thans for your complimnt - actually Ive changed it a bit since those pics were taken so I might post a new photo later when I get home from work.

To answer your questions:

1. Dont know exactly what sat cables I used, it was one I had lying around; I think it must have been one I got with a sat dish from Lidl many moons ago - Ill have a look tonite and c if there is any writing on it that may indicate what it is, but to be honest, Im not sure if it is a good quality cable or not.
2. Yes, the F connectors r gold plated.
3. I think the elevation is about 26, but Ill have a look tonite when I get home and post exacly what it is. FYI, I understand that one should try and get the highest elevation possible.

Till later
Regards

The f-connectors can't be that good if he has to use that crappy tape on them & those big ugly lnbs must be about the worst thing for that kind of setup.

It's just all bog standard gear with no real ingenuity apart from the cable tie on the centre lnb. :rolleyes:

Ronnie,

Ur post is rude, vulgar and offensive - if you have nothing nice to say, dont say anything at all.

What?! This is supposed to be a tech forum and I presume I'm not addressing a child, so you can take a bit of criticism.

If I see an installation being praised by others & I think the praise is unwarranted, I don't see why I shouldn't point it out.

GB Cullen,

I checked the elevation and its 26. Cant see any writing on the cable, but then again its very dark outside

Heres some new pics that might help u.

Why do 28E & 19E appear to have the same seperation from 26E & why is 19E skewed differently than the others?

What did you use for signal display while setting up?

Peter,

I dont know the answer to ur questions. I just moved the LNBs along the bar until i got the strongest signals .

I just used my Set Top Box, basically the hard thing is to tune in Badr, the signal is weak, a4ter that the rest is easy.

What channels do you get on this '19 east'? Sure it's not 23.5 east?

I have ones like:

Das Vierte, Deutsche Girls 2, DMAX, Erotik Sat, GoTV, kosmica TV, Munchen TV, Radio Bremen TV - a load o4 rubbish really.

Peter Rhea

That's mostly 19.2E, although Kosmica tv only seems to be on Astra 3B @ 23.5E (it shares a tp frequency with Astra 1M).

Thats interesting, thanks 4 that.

But at the end o4 the day it dosent really matter 2 me coz the birds I need/use r astra 28, Badr 26 and Hotbird 13

But thanks again 4 the in4o.

Peter Rhea

On digging further, I see Kosmica was on Astra 1H @19E (12480 mHz, vertical) until 1st October.

Is your version on this tp & has it ceased transmitting?

Let me check.

Yeah ur right - its in the list o4 stations, but theres no pic, it says 'The channell is scrambled or currently not available'

many thanks iba much appreciated, what make and model of receiver are you using? 26 elevation is about spot on, you will need to take a screen shot of a well known channel on each sat and post back here to prove the rig works as you have it working. Those lnbs are the dogs boolks as they say in the trade as they are slimline with a long neck and makes the space between each lnb look a lot more than it actually is and that is why you have it working perfect. A lot of people assume that only fat lnb's are proper lnb's as they are only used to Sky stuff. Using a fat lnb on a triax is well nigh impossible to get it to work The trick of moving 26 to be the focal point on the actual arm is the real secret as a lot of people assume you cant adjust the triax lnb holder. Another trick with the triax lnb holder is to turn it upside to get correct angle for sats. Especially in getting the arc to the west.

And your method of sliding bar is the simplest and most effective. I am asking on behalf of another poster and for my own information. I did a lot of muti sat suff when in abroad but lnb's in my time were not as good as todays. It meant using slimline alps ones and a bugger to get quads. The beauty of the quads is you can do wonderoas things with the correct receivers.

And there is one particular receiver that would work like a dream(no not that make) and there is a lot of english programmes on 19east as well. I have a motorised set up now and a static sky dish and an octo lnb.

at peter, the pics will not give you the exact setup as is it illusory, if it was a fat lnb then the gap would be nil, the lnb's used are slimline. the skew on 19 is necessary for the actual poistion of the satellite in the sky remeber this is a multi sat rig, its not supposed to work so you fool the lnbs to grab its distinct sat signals. This is not a case of putting up dish, attaching an lnb and bingo there is the sat. This type of work takes ages but the reward is getting it spot on. You are taking signals from 4 sats that individually may give 100% quality on a 1.1m dish but this is then downscaled to say 60 quality and that is enough for perfect pictures even in rain. And each sat is more powerful than the other. With quad lnbs you can have unlimited potential and its instant zapping and no noise.


thanks again iba

They're still 40mm necks with big end caps aren't they & why would being 'slimline' make any difference to the relative spacing (& how do you fool an lnb)?

swoofer

thats a secret, wait for the screen grabs, are you interested in doing something similar?

The STB is a Humax 4oxsat HDR

Heres some photos:

1st is Dmax on Astra 19, then ITV1 HD on astra 28, then MBC2 on Badr and 4inally Polonia 1 on Hotbird

I then have all the LNBs connected with 2 cables going to diseqc Switches. With one Diseqc switch going upstairs and one downstairs.

I have to say Im not an expert and I learnt a lot 4rom Banie, Watty and Zardoz on other threads in here and other guys whose names I cant remember.

Two o4 my LLNBs r a little 4at, but they work so whats it matter.

Yes I turned the rail upside down.

But as u say, once i got Badr, the rest was simple enough.

Im not getting 100% singal but around 80% - they work, so thats cool.

I have tow quads, but really i only need duals, but I picked up teh quads cheap over in the Middle East and they work so why not use them.

Photos im a4raid arent great - but the battery in cam went dead.

brilliant, i knew it, it had to be a receiver with one of the finest tuners ever made or I should say the most sensitive, it will pick up signals other receivers wont even sniff. They are prized in europe as they are known to even pick up BBC HD . That's why the system works so well.

I am not bothered about the pics as I know it works. And for a beginner you have done well,, in fact a good bit better than well. 80% signal, wow.

much appreciated all the effort you took to post back.

Great pics iba, good to see them working. I hope I can sort mine as good.

GB, not sure of where you are in Europe, but Satfinder dishpointer gives me an elevation of 22.4 and I am not too far from iba.

How critical is elevation? Also dishpointer gives the skew which I presume is for each satellite assuming it is the prime one, so if LNB is not the prime, ie 28, 19 or 13 in my case, it would only be a starting point. Is this correct?

Also, I still have to admit that iba's lnb's do not look like slime-line ones. I would be thinkink of Alps and similar as slime-line, ones with very small ends that will sit close.

Cheers

TC.

hi tc ye are both neighbours so use exact same set up, dont worry about the lnbs, dishpointer cant cope with 4 lnbs, so ignore.

ELEVATION on dish is key.

So trax 1.1m , 26 elevation, turn holder upside down, find out from iba exactly where to drill the hole for 26 as that is the key ie the weakest sat, once you get that the rest is easy. and dont worry about skew, the holder compensates. You only skew afterwards to fine tune.

By the way IBA' receiver is very sensitive but I know technomates are pretty good as well.

Dont worry about the size of lnb's, have a look at at few setups and then compare with IBA.S.

But do reinforce the lnb arm on the dish.

What I will do is take a screenshot of a channel on each sat, and get the strongest transponder, screenshot with show channel, frequency, signal/quality and the damm LOGO.

I might do one in a mo but defenitely by tomoro.

They look like every other standard feedhorn 40mm lnb to me; what exactly do you mean by slimline?

Anyway, I'll judge the spacings by looking at the holders rather than the body of the lnb.

The beauty of the quads is you can do wonderoas things with the correct receivers.

Wondrous?! Like what?

there is a lot of english programmes on 19east as well.

Where?

the skew on 19 is necessary for the actual poistion of the satellite in the sky remeber this is a multi sat rig, its not supposed to work so you fool the lnbs to grab its distinct sat signals.

It only takes ages if you don't know what you're doing, the basic idea is simple. The "actual position" of the Astra 1 satellites is above the equator at 19.2 degrees longitude; how is that a special case where skew is concerned, no matter what the offset?

Thanks very much for your kind words GB.

Just trying to repay the good karma coz I said, I would not hvae been able to do this without the help of people like Watty, Banie and zardoz and others.

A word of perserverence though, getting Badr 26 is hard hard work, but once you get that the rest just falls into place.

Thanks - I hope it works out for u 2.

As for elevation, I read on another thread that one should aim for the highest elevation - as I said in a previous post, Im really no expert at all, just a beginner so I followed that advise and it worked. But whether its right or wrong I really cannot say. It may be that if you are only using one LNB and aiming for Badr then the 22.4 elevation is best but if doing a multi set-up maybe the 26 is best. But Im only guessing.

I didnt take the skew figures from Dishpointer or anywhere, I just moved the LNBs left and right until I was receiving the strongest signal - again the skew numbers in dishpointer may be referring to just a single LNB set-up; but again Im only guessing.

The 2 LNBs for Astra 28 and Badr 26 are reasonable big, but they fitted so I didnt need to go for skinny ones. The black LNB for Hotbird though is skinny and is top of the range as far as I know. Bought it on Ebay from the UK for about €26 including postage. I needed this coz Im watching premiership football on Canal + Poland on the signal was is a little weak but comes in fine with this LNB.

Tony - my advice would be, sort out Badr first and then do the rest. Badr is by far teh hardest to get.

BTW - the cheapest place I found Diseqc switches was from a sat shop in Ennis approx €6 and the Quad Triax holder can be got for €15, (but from a different shop).

Hope this helps.

I don't see how this could be the case if the lnb for 26 is (properly) at prime focus. The satellites don't move.

Isn't the new hole in the bar to move it off centre & allow reception of 13E?

No need to turn it upside down if you're reboring it anyway.
