i know this is two opposite sides of the spectrum for questions but i have been reading how adding a spacer can improve the 741s ku reception. i have one i bought a while ago laying around with a conical scaler ring and was going to try it as minibud. is it better to dump on fleebay or put it on the dish? or would my time be better spent getting a hd card for the computer? which one might bring better gains? missed hd channels on ku or a minibud trial and error?
