Advice Needed 16 east footprint vs reality

[Analoguesat]

I went to Wolverhampton Polytechnic as it was back then.

My favourite beer is still Banks's Mild, although I cant get it up here, although the Bitter turns up in our Tesco occassionally! I still have a hankering for the long lost Springfield Bitter too

I am more of Holdens man myself

Did a tour of the Banks's Brewery not long back and it was really enjoyable.

Yeah the long lost Springfield Brewery has been regenerated by the University now after years of dereliction and fire damage.


Back to Sat talk, I will give the Triax a go tomorrow and see if I can get 16e. I am quite confident I can get my hands on a Gilbertini OP85L if I need it. I have heard good things about these, that they perform like 'some' 1m dishes? Do they take multi LNB setups? I wouldn't mind 16e and 19.2e.

16°E comes in here (Gloucestershire) on a zone 2 Sky dish, but some transponders are missing (I've never been able to lock the Czech and Slovak transponders), and others can be borderline. There isn't much in the way of rain margin. As mentioned, 11637 with the Slovenian/Croatian public channels is pretty strong.

I have checked the zone 2 and my dish and they’re very similar in terms of gain etc so it should be doable.

I’ll give 11637V another go again tomorrow and see if I can get an improvement on it.

I have seen it is a pretty difficult Sat to get a lock on so could take some time.

Perfect conditions down here today - not a cloud in the sky.

Hopefully it is the same when I finish work.

 

[cwsat]

Been going at it a good hour and a half and I just can’t lock onto 16e.

I’ve had Hotbird nice and strong, moved around, I’m getting 28% quality 50% strength on my meter but no lock on 11637V.

UPDATE : Just purchased a Gilbertini OP85. Hopefully I can pull it in on that. Heard great things about the Gilbertini dishes.

Set the Gilbertini 85cm up tonight and still nothing - it’s actually performing worse than my 65cm triax.

Something is amiss. It’s so frustrating.

Considering elevating the dish just in case the wall near it is impacting the signal. Surely 13 and 19.2 would also be impeded?

 

[Mickha]

13E and 19.2E are extremely strong signals, available on a lot smaller dish, so perhaps only part of the signal is being blocked.
Can you please post your signal quality readings, and channel names, that you're receiving on 13E and 19.2E.

Dishpointer has an object obstruction calculator that works out if objects could impact on line of sight.
It's just a bit of geometry maths.

Nowt to be lost by raising the dish if it remains at a safe working height.

I have a feeling the wall is causing an issue.

I used the app satellite finder earlier off the Apple store and sat my phone just above the LNB arm.

I tipped my phone back so the target hit the sat, which I think is what you do and the top of the wall is bang on where the satellite is on the app.

13east is just above the wall to the right.

Plan later is to raise it a good foot or 2 and try again.

I am not giving up on this, especially as I drove a 2 hour round trip yesterday to pick the dish up.

Persistence is what we like on this forum.

I will report back with some signal quality readings later / tomorrow but on the Triax 64 I was getting 89% quality on Rai Uno on Hotbird on my meter.

Nudged the dish around and got 27/28% quality on 16e on the TD64.

My plan tomorrow as the weather is awful down here today is elevate the dish on some breeze blocks, make sure 13 and 19.2 are booming in again and then start trying to get 16e.

In the not far off the same location on my old 1M orbital I used to get 82% quality on 16e on a clear day.

27-28% doesn't mean a lot, unless you can post the transponder details, so that others can test it, and look at the satellite footprint. 89%, on 13E, seems to be good, on a 64cm dish.
The photo, you posted, appears to show the dish close to the wall.
Have you tried dishpointer, they also have an obstacle checker option, to see if the wall is causing problems.
Is the dish on the ground, or a pole?

28% was on 11637V on 16e on the 64cm.

The wall is around 7ft tall and about 2.5 meters away from the LNB. The LNB arm on the Gilbertini is a fair bit bigger than the Triax 64 so closer to the wall, maybe that is the reason for the lower levels on the Gilbertini.

I haven't tried dishpointer but I have tried satellite finder, that's where the screen shot of the wall and LNB came from.

It is on a camping tripod / mount.

 

[Mickha]

I think you should raise the dish, if only temporarily, and see if your signal quality improves. I know photos can shorten, or lengthen, distances, but that doesn't look like 2.5M, from the LNB, to the wall, but then again the wall looks taller, so perspective is difficult.
Using dishpointer, and my location, it estimates that for a distance of 2.4M the object needs to be less than 1.2M, to avoid signal degradation, for 16.7E, but this measures from the base of the dish, not the LNB.
The distance, from the dish, to the LNB, shouldn't affect the signal received, this is from the satellite, to the dish. The fact that your dish is now bigger, so probably is lower down, at least at the bottom, is more likely the problem.
I would like to know the signal quality readings, on 19.2E, as the further East you go the lower the satellite, from your high point, which is your true south, logitude, reading.

The wall is around 7ft tall and about 2.5 meters away from the LNB.

If the elevation of 16°E is 28° at your location then the bottom of the dish needs to be 1.67 (45/elevation) x obstacle height away from the wall.

Reckon that wall is your problem. Have you any other location on the property that has a greater clearance from obstacles. That will take the guesswork out of the equation. It’s difficult from the picture to get a sense of your surroundings. As mentioned raise the dish from the ground as much as possible. 11637 V is quite a powerful transponder.

There is nothing the other side of that wall for a good 75m in terms of buildings or trees so nothing blocking line of sight.

The only reason I thought clearance was not an issue is because I have had 19.2 and 13 from an 80cm dish sitting on a car tyre before.

I will do a few measurements tomorrow, wall weight, dish height and distance from LNB to wall before I elevate it.

If needs be I’ll take the dish out into the garden which has a full clear view of the East and West arc.

That’s exactly what you need to do. It will confirm if your dish is the problem and not the obstacles. That TP you’re trying to aim at on 16e is quite powerful. Once you’re clear of any potential obstacles I reckon you’ll lock it.
