I've no idea what happened to it but it somehow misted up - I couldn't see through it. I thought it might have been condensation but it turned out to be the adhesive on the back of it somehow melting and turning into goo. So I removed it now!While I was up there and the weather was nice, I decided to put my Channel Master on for comparison. The results are fairly conclusive. In most cases the Channel Master gave readings between 1 and 1.5dB lower than the Fibo, which is a lot when feed-hunting. I tried the CM with its proper feedhorn and the Black Pro C120 as well as with the Black Ultra. BU gave slightly better performance overall but the feedhorn looks better <img src="https://www.satellites.co.uk/styles/default/xenforo/smilies/smile.png"  class="smilie" loading="lazy" alt=":)" title="Smile    :)" data-shortname=":)" />I put the Fibo back on and realigned it on the arc again. Used reference points of 37.5W (Dove Vision 9.3d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />, 31.5W (ORTM 7.2d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />, 30W (Al Jaz 17.1d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />, 22W (Beach Cams 16.3d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />, 5W (Canal Algerie 9.2d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" /> and 36E Sub Saharan beam (12245H - 6.8dB but occasionally goes over 7d<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite6" alt=":cool:" title="Cool    :cool:" loading="lazy" data-shortname=":cool:" />.With the Channel Master, I couldn't get much above 6dB on 36E, Beach Cams on 22W were low to mid 15dB and Canal Algerie on 5W I could not get about 8dB.Was a bit of a pain as every time I tightened up the bolts the dish went off alignment. So a bit of trial and error and a lot of luck was necessary.So there you have it. The Fibo really does have the edge over Channel Master. I am sure with more tweaking, I could have squeezed maybe a bit more out of the CM but it was becoming hard work.</blockquote>
