[QUOTE="Vipersan, post: 786553, member: 325666"] Ok ...so I've come to accept oddities and compromises are all part of this project .. The repositioning of the boresight was essential ..and has proved worthwhile .. I can now get 2x startimes transponders at noon uk time 10 East (see pics) ..and a variable lock on Dunia 30 East (see pics)....and AFN family 1W ... So ..all good you might think .. With a commercial plate and the old style T plate AFN locks immediately ...1 transponder possible Startimes ..and is infrequent /unstable and No pics from Kung fu ...dunia is just below lock theshold.. Add the Vscalar plate ...and the Modified (looks like a comb) T plate ....and you have what I listed at first..BUT AFN ...takes time to lock ...its as though the system has to wait isolate and process the signal cloud build up at the plate ...it can take up to 6 seconds to lock ...but once locked ..is stable at a reduced by .3 db signal A tradeoff indeed ..but the assembly as is in the picture ...VScaler feed and Comb T plate outperforms for sure .. My guess the tradeoff for the extra gain is slight instability... rgds VS [/QUOTE]
