I have recently got a used 1.6 metre dish to go with my Humax receiver and am trying to get reception of Nilesat 7w. I am based near Manchester (53 N, 2 W). Having searched these forums, I see that there are several members receiving the vertical transponders (the horizontal ones seem pretty impossible in the UK) on 1.2 metre dishes. The reception on my 1.6m is very poor. The education channels are the only ones I can receive with any regularity. Last weekend I managed a couple of other transponders with blocking and intermittent signal.
I have peaked every setting. The dish is as perfectly aligned as I can get it and I have adjusted the Skew and focus of the feedhorn. I am now turning my attention to the feed/lnb.
The current setup is a Cambridge Ae33 0.7dB C120 coupled to a Cambridge feedhorn. I know that the LNB isnt the best in the world and am considering an Invocom 0.3dB. Also, the feedhorn has a little corrosion (oxidisation) on the surface of the scalar rings.
Will the oxidisation affect the performance of the feed to any extent? If I replace the feed/LNB, am I better with a C120 setup or a combined LNB/Feed? I have read that combined LNB/feedhorns don't really work so good on big dishes.
Finally, I will have the opportunity to try out a 2.4 metre dish in the next couple of weeks. Does anyone think it is likely that it will pull in any of the Horizontal transponders?
Many thanks in advance for any help you may give. It has been 10 years since I last messed about with satellites and this forum has really helped me bring myself up to speed.
