Reception reports of the Astra 2E UK Spot beam at 28.2E
Full frequency list can be found here. Astra 2E
The background shows a theoretical foot print of the Astra 2F UK spot beam at the frequency 10.773 GHz. The red stripes are the theoretical “dead zone” between the footprint and side lobe.
The theoretical footprint is calculated at this site. www.satellite-calculations.com
To the left you can see some tables. The first one is shows how you can recalculate your signal quality to SNR (signal to noise ratio) dB.
The second one shows how much signal strength you must have to get a “lock” on the transponder and margin for bad weather.
The third one show how much amplification you will get with different dish sizes. OF is Offset dish, PF is Prime Focus dish, PF 6 is a Prime Focus with 6 petals and PF 8 N is a Prime Focus dish with 8 petals net construction.

All dish sizes are in meters.
Green 24/7 reception > 8.7 dB SNR
Yellow Some signal during the day or low rain margin 8.0 – 5.2 dB SNR
Red No lock on the transponder < 5.2 dB SNR
