Can I get necessary sats on 80cm dish

SteJay

Hoping someone could tell me for definite if I would be ok to receive from 0.8w to 30e on an 80cm motorised dish in Tramore, Waterford?

I'd prefer an 80 over any bigger ones as the irish seller I found only does 80 or 1m and 1m would be too big

cheers

You'll get very little on 0.8.

A few transponders on 4.8.

A few transponders on 7.

9 east no problem.

Virtually nothing on 10e.

13e, 16e and 19.2 e no problem.

21.6 nothing.

23.5 no problem

26 east nothing

28.2 no problem

Thanks for the reply.so is an 80cm dish big enough for all them satellites

dxhound2005

10 East at present TV Zimbo Broadcast 10756 V 2480 18.3 dB.

21.6 East Azal Satellite Channel 11691 V 1445 12.5 dB.

That is on a 110 cm. dish but they are much stronger than some on 28 East. Signal strengths can vary a lot on some satellites but there are quite a few other strong ones on 10 East. TV Zimbo is just about the strongest anywhere on the arc just now.

The ones I mentioned you'd pick up, yes.

The ones I mentioned you wouldn't get much or anything, no.

Get a 1.1 triax while ur at it and pretty reasonable

Ah well he is going to limit certain sats then,

I am down South, not as far south as Tramore, but just to add to/correct Radiowaves list. Reception of some sats improves the further South you go.

I use a TD88 dish which is 88cm.

10E/7E/0.8E These sats are used a lot for links for football/sport/Tv links. Reception is fine on a TD88.

26E. The MBC channels are FTA and mainly show films/US TV series. Dubai Racing and Sports channels show racing from Meydan/HRTV programmes. All are receivable.

23.5E is used for links (incl GAA) in addition to mainly Dutch and Bulgarian TV.

Thanks for the additions - if the OP is interested in feeds that should help him. My list concentrated on standard broadcast channels - feeds are transitory by their very nature.

The one correction you made I would have to in turn correct. The 26E channels are fringe reception channels. The drop from your 88cm to his 80cm would extremely adversely affect his ability to receive the quoted channels, but even if he managed it chances are that any adverse change in the weather (even heavy cloud cover) would knock them out very easily .

For sure its on the fringe on 26E - even a 50% SNR will be wiped out in very heavy rain. For that particular sat the further south you are the less dependecy on a bigger dish. Tramore is right on the margin for 45dbw (90cm). The signals drops to 43dbw (100cm) in Sligo/Donegal/West coast.


But 10E/7E and 0.8E are all very strong but whilst they do not have a lot of content in terms of FTA UK content, its a happy hunting ground for links on a 88cm and up. I am presuming that most people who are going to the bother of installing a motorised dish are interested in same.

For clarification, the OP is asking about an 80cm.

For further clarification that's what my list is based on - reliable reception on an 80cm.

Personally I wanted every sat possible so have a range of dishes - links were of little interest to me but prove of interest now and again.

And that was my point radiowaves.

I am using a TD88, and my experiences. So if I am getting away it for those, it might suit the OP. They are also good against corrosion.

Sure if that's the case then I'd be recommending bigger again but the OP specifically asked about an 80cm - also suggesting 80cm or 1m were his only options and 1m was not a goer.

Anyway, if that was your point I'm not really sure why you were "correcting" me but thanks for the later clarification

Jaysus. Its not personal (I didnt agree with 10E though).

Bigger is always better.

Look, lets take purplesats measurements for 80cm. (It would reflect my experiences of setting one of those smart dishes up for a mate, here in the south east)

I have enough experience myself of different dish sizes around the country.

Even a quick glance at your graph leads me to ask: 5east - strong. Really? 42 east - very strong? That graph seems to be just taking the strongest transponders and leaving it at that.

As you and I both know different circumstances (LNB types, LNB NF, make of dish just as examples) can also all have a bearing.

I mean 10 east, I struggle for most transponders on a 1.2m - not that there's much on it anyway. The quoted TV Zimbo was suffering badly with rainfade last time I viewed. I notice since that power has shot up.

So when someone asks about reception I post what's reliable based on my own experience. If yours is different on the same size dish then that's what forums are for.

I currently have 28,23 19 and 13 on a triax 78cm dish...........however over the last few days the rain fade on some of the 13 east transponders is resulting in a poor reception..........would installing a Triax 88cm dish make much of an improvement.

Thanks

For some transponders on Hotbird you need a prime-focused 80cm dish for reliable reception.

I lose none of them on a T90 so depending on what satellite you prime-focus on you should be ok..

Since I swopped in a black inverto lnb, I've had no problems on 0.8.
What channels do you pick up on 16? i dd a scan recently and only got around 30 channels. I was looking for tring. (on a 98cm dish).

Scandanavian HDs have very low tolerance to rain with a black inverto on a 1.2m (in my expericence). All other channels beam in without issues.

Tring covers just two transponders but I have absolutely no issues on Wave T90. It might be worth ensuring you have the correct transpondes in your database.

The LNB is really irrelevant unless it's junk. FAR more important is LNB skew, dish size, alignment, correct focus rings on LNB for shape of dish.

That's absolute rubbish :rolleyes:

The difference LNBs make has been well-documented (even just in the couple of posts prior to yours!!!).

I can view dozens of channels thanks to a simple swapover of LNBs to Inverto.

Obviously the other things you list are more important but to say changing the type of LNB is irrelevant is utter madness.

Thankfully I just changed my LNB and am now getting channels I was missing. Otherwise the expense in buying in bigger dishes and the time wasted in putting them up and aligning them if I'd read your post first would've seriously ticked me off

watty

The other LNB must have been junk or wrong skew or wrong type for your dish.
I don't base comments on hearsay, anecdotal evidence etc, no matter how many times repeated on internet, but on 30+ years as Communications/RF Engineer, being able to do the maths etc. Weather (even in an apparently clear sky) has a huge dramatic effect.

Any change due to swapping non-junk LNBs is absolutely marginal compared to weather. If you have good enough rain margin then you get NO extra channels changing non-junk LNBs which have correct focus rings for F/D and shape/Offset of dish and skew is correct.

I've replaced a number of (varying) LNBs on a Wavefrontier dish; on a motorised dish not to mention on dishes throughout the years - there has always been an improvement with Invertos. Always. Not sometimes. Not every now and again. Always.

So no matter how many times you repeat something on the internet; based on my actual experience (and that of many, many others on these threads alone) and on talking to many people who install dishes for a living, I have to respectfully suggest that your

30+ years as Communications/RF Engineer, being able to do the maths etc.

have been wasted if your position on LNBs is so patently balderdash.

Loved that bit. It can't be simply that you're wrong :rolleyes:

What do you class as junk? For me a LNB makes all the difference in a good setup.

A cheaper LNB is fine for the strong footprints, but for marginal footprints a much better LNB is always recommended.

I use a trusty old titanium .1 lnb that is great for the marginal channels here.

Other brand name lnbs just dont cut the mustard unfortunately but are fine for the strong footprints that are commonly received.

I always agree and read your posts with enthusiasm Watty, but the LNB post i have to say I completely disagree with you.

I would like to see what you class as "Junk" compared to being "Good".

You kind of contradict yourself by saying one LNB is junk and another is good??

Its like saying an "opticum" (Very popular here in Poland), is Junk and an Inverto is good?? But that's what we are saying? (Even though the Opticum is not junk, its grand for strong beams, but not for marginal professional setups?

watty

A common problem is LNB horn/dielectric spike/Fresnel ring lens is for a different shape or F/D of dish to the dish you have.

Any good quality LNB is as good as an Inverto. They are not magic.

Tell you what: you stick to swapping out dishes and the rest of us can stick to trying LNB swaps first to see if they improve our reception issues

In fact, you stick to your 30 years worth of maths and I will stick to the practical results I've personally seen from every LNB swapout I've ever done.
