[QUOTE="Chromatron, post: 713725, member: 358887"] The cheap C-band LNBs available on eBay do work, although they're designed for linear polarisation - a dielectric plate will convert them to circular polarisation though not very efficiently. To use with my Triax TD110 I made a conical feed-horn from tinplate, "designed" empirically (i.e. guesswork), but it certainly works after a fashion, though I expect that proper elliptical scalar rings would improve performance. I got good results from BadrC when it was still active, including the analogue channels, but there doesn't seem to be so much high power C-band around these days. 4158R at 5W is quite a strong transponder but for an initial experiment 3675R at 40E is probably the strongest C-band signal in the UK. (4196L on Arabsat 2B used to have that distinction but the advent of Arabsat 5A put an end to it) [/QUOTE]
