Dish size recommendation

[7mdish]

Hello, which dish size is needed to get NS4 transponders at 10 and 7 East? This question comes from a friend working in a little TV broadcaster. He asked to me but I'm not sure. We are in Milan, northern part of Italy. Any advice? Thanks.

Advice Needed - Eutelsat 10A (10.0°E) In UK

Hi, I am checking whether it is possible to receive satellite channels in London from the Eutelsat 10A 10.0E Satellite on C-band beams? I have checked the footprints for this satellite and I can see beams reaching the UK on 40dbw. The particular channels I am interested in are NTV Uganda, WBS...

Whilst forum members would be happy to pick up signals with whatever they have to hand, a broadcast company would use link budget calculations to determine the equipment required before parting with the money.

So, they are a very little TV station, and I believe they must receive some specific service from Hypermux frequency at 10 East (I have no more details yet). I hope to have chance to test again that Novelsat receiver when my friend will get one, I just tested such box some years ago. The problem is they must arrange a specific dish, I believe that 1.8m is enough but I'm not sure, so I asked here. Now I check the link posted above by William (Hi William, hoping you are well). Thanks.

I forgot to mention that I'm speaking about Ku band transponders, not C band. The problem would be modulation type (NS4 16APSK). Thanks.

A 1.8m or 2.0m dish should be OK.

The picture attached below is a screen shot taken today showing an NS4 signal with modulation of 16APSK in Ku-Band from 10.0E that was locked using a 2.0m dish
The link margin with a 2.0m dish is 4.59db.

Thank you.

Be very careful as to the size of the dish used for re-broadcast purposes in a small TV station. The Ku band is severely affected by heavy rain and snow.

This is why we always went 6 to 9 dB bigger on the recommended dish size,(approximately 3 dB for each 100 mm diameter increase) if satbeams recommends a 1 metre dish then go with a 1.3 to 1.5 metre dish. Less fade out problems with a higher gain dish.(2 metre would work fine)

In some parts of the US we used 8 foot dishes for Ku band signals.

The threshold of reliable reception above ground noise was 10.5-11.5dB at Ku band frequencies when I were a lad.

So what has changed ? Certainly not the weather.

Probably not the level of the "highest intensity", but definitely the frequency thereof.

Very useful advice, thank you. Yes I know that, in fact I thought and told to my friend that 1.8m would be fine but I was not sure so I asked here. And you confirmed my thought. Thanks.
