...did a C band scan this afternoon and receiving 46 C band signals with a Q of 75 and Sig 70 from the way the signal is I would say there circular polarisation so the Norsat 3120F is working well . This is on Astra 4 / Sirius 2_3 Vert + Hoz...
The C-Band signals from 4.9E are all circular polarity but with your dish size you will be overcoming the signal loss caused by lack of a dielectric plate, unless you recently installed a dielectric plate in the feed throat?
The UK beam foorprint coverage of 4.9E in C-Band is reasonable, the bin lid kids are getting signals from it round 'ere. I have attached a table below of a scan I did last year on 4.9E in C-Band. I locked 13 of the 17 frequencies listed at the time with a Precision 2.0m dish. Once your 3.7m dish has the feed arrangement correctly aligned you should be wiping the floor with my humble signal levels if you are not already doing so.
A good test would be to get that dish on 38.0E and 43.1W in C-Band. They are both linear polarity and not an easy catch in the UK. They are truly satellites for the big dish men.
