[QUOTE="moonbase, post: 1134325, member: 178786"] [USER=296628]@nelson_b[/USER] Thank you for sharing your test results. Interesting and perhaps unexpected that the AV-COMM polo pipe could not perform as well as an LNBF with dielectric plate? I found the opposite on tests I did with a prime focus dish 'ere down Saarf where the polo pipe had the edge by about 1dB, possibly a little more. However, it was a while ago that I did the tests and C-Band signal levels on these satellites seems to be changing quite a bit. Perhaps due to a 1.8m dish being on the threshold for these signals from 40.5W the results would be different if you hit it with one of your big lads? Tests for another day perhaps, from the 2.4m CM or the Patriot 3.0m? For anyone interested, last time I checked AliExpress a few days ago, one of the stores had stocks of some Gardiner WR229 block LNB's. I don't think they were the exact same model used by [USER=296628]@nelson_b[/USER] in his tests but they were the same block design by Gardiner.
