[QUOTE="nelson_b, post: 722669, member: 296628"] hi -- just to report some findings regarding skew of the dielectric plate on circular transponders ,i,v been testing out the C band performance on some sats using a (small dish) 1.2 channel master on a fixed mount -- with pauxis l.n.b.and conical feed i was looking at 40.5 west tonight and found that i could make quite large increases in signal on this sat by setting the "doctorofsat" dielectric plate slightly off centre from its normal position within the grooves -- as well as sitting it high up in the l.n.b throat -- ( a normal dielctric plate barely gave any signal) on tv brazil- and on other transponders i almost doubled the quality reading by doing this -- and on cristovision it made the difference from no signal at all - to getting a watchable picture with no breakup -- this kind of skewing of the plate did not apply on 1 west when i set it up last week -- although only 1 transponder could be received from that sat with this dish i must add that skewing the whole l.n.b. seems to make no difference to the signal of circular transponders on this fixed dish setup i will be trying other sats for C band with the 1.2 as/when i get the time :) cheers nelson.b.
