[QUOTE="Vipersan, post: 862034, member: 325666"] Ok ..here is the compromise .. Working well atm ..but then it is a clear rain free day .. I'd estimate roughly 1db of loss per shift from focus of 3 degrees..but I can still lock Ocko today at 5.4db on the SL3 Ka lnb band D at the focus and the ku to the right as viewed from the dish. The thick rimmed specs (cover) of the SL3 fee copper feed has been removed ..and am contemplating trimming down the diameter of the cone to allow closer placement of the feed to the focus without casting a shadow over the Ka centrallly placed lnb. I estimate I can get about 1degree closer to focus without any serious degradation of signal capture by a reduced diameter cone. In Ka every 0.2db counts...!! rgds VS [/QUOTE]
