Wave Frontier T-55 setup (European Mainstream TV)

[Terryl]

Is the drop in reception affecting the quality of the picture???? If not then don't mess with it, the signals are now digital, you don't need to get every ounce of signal possible to get a clean looking picture, now if you having signal drop outs, or picture quality problem on the end LNB's then yes a re-alignment would be needed.

Remember, the signal strength indication (S) on the receiver is measuring the signal coming down from the LNB's output, and the quality indication (Q) is calculating how many bit errors in the signal that have to be corrected, the lower the Q the more bit errors are being corrected.

 

[ozumo]

Measure the signal before and after the switch, to see if the switch is going bad, a slight loss in signal strength is to be expected, but quality should be the same. Then check to see if the dish has rotated around the pole, a light pull of either side of the dish should be enough to see if signal rises or falls.

I wondered if anyone had any ideas on which aspect of the dish I should tweak first?

With multifeed dish tweaking, always first check the dish skew (you can only trust the scale for that, if your pole is really plumb).
You can trust the calculated satlex value for dish skew, I suppose.

After that, the elevation for the eastward and westward satellites for your location should be as they should, so you can go further tweaking on the LNB positions on the rail.

It's only an issue when the weather isn't great. Heavier rain means loss of picture on the weaker LNBs.

It's only an issue when the weather isn't great, so when I'd want to be watching TV . Heavier rain means loss of signal on the ones with weaker reception.

Thanks. I think some tweaking may be in order...

I like your idea of pulling the dish slightly before totally commuting to moving everything. Baby steps

My little dish ! Picks up alot more then you think!

28e - very strong
23e - very strong
19e - very strong
13e - very strong
9e - very strong
5e - quite strong
1w - black ultra lnb required as this is a weaker sat
5w - Italian & French multistream works fine but weak

A high quality switch is required such as a ATEMIO. This is because you can get interference with 8 inputs such as dead TPs on certain frequencies.

Nice! I’m guessing 13°E or 9°E are around your centre position?

I’m thinking you’re probably Southern half of England to be getting 5°W Multistream on this kind of set-up?

I’m pretty tempted looking at this to do similar myself. Alongside a second regular dish for 30°W this would give me everything I’d be after.

Interesting how the LNBs closest the the camera are mounted near to the feed horn, while those furthest away are mounted towards the rear of the LNB neck. Did you find long neck LNBs to be necessary to maximise signal?

 

[mike1]

Hi
Yes 13e is central focus.
The lnbs 19 23 28 are using T90 lnb holders (wrong lnb fixture for T55) thats why they look higher up. But they can compensate for being higher off the rail as the signal is very strong!
They are all long neck lnbs 1w & 5e have a black ultra the others are cheap icecrypt ones.

Any chance you can share approx. your location as this would help in configuring dish. what is your scew on it ?

Did you ever try 16e on that? I assume it was too small.

 

[mike1]

Not sure will look in the morning - Im in Hull UK
I never used a screw calculator .
Find 0.8w or 1.9e first as far out on the bar (As these are the weakest) Then tighten the antenna when you got the strongest signal on these.

 

[jeallen01]

... I never used a screw calculator ....

"screw"?? Surely you mean "skew"!

PS: OTOH, there are a few other things for which a "screw calculator" might be handy, e.g. a "night on the town"

 

[rodscha]

Would that great looking intallation work in South France 42°/2°E approximately?(Carcassonne)?

28e - very strong
23e - very strong
19e - very strong
13e - very strong
9e - very strong

I m very tempted at this

Don't think you'll get the UK beam of 28.2°E on a T55. There's also the larger T90 version but that may also be too small for the UK beam at your location.

 

[rodscha]

yes of course!!! i have a dedicated120cm for astra2
would a t 90 suffice for the other sats?
actually what I 'd like would be: 1w/5 e/9E/13e /19e /26e(as i have 28 on a separate dish)
Other problem ,a quick check told me the T90 isn t avalable...made in China or Ukraine?

 

[ozumo]

The Nordic beams of 5°E & 1°W (+Thor 7?) won't be possible and I don't know how strong 26°E is at your location. I think I read the T90 performs like a 70cm dish for LNBs mounted at the outer points of the rail, if you think that size dish would be big enough for the satellites you want it should work ok.

The Visiosat/Cahors Big Bisat may also be an option and is available to buy, not particularly cheap mind.

 

[deeptho]

Here you can see the performance drop in terms of azimuth. Note that the displayed
range corresponds to a difference in satellite position of about 40 dgrees. So the east and west-most
satellites are 20 degrees from the center one. The loss in gain is about 1.5dB. Even at the boundaries,
this seems similar to a 90cm dish. For the T55, the numbers will be different of course.

It is also essential to use the correct lnb holders for optimal performance.
