[QUOTE="nelson_b, post: 647443, member: 296628"] hi - Satcom1 - to be honest i,v never compared the conical Scalar to a flat scalar until very recently i was under the impression that a conical feed was needed-- on a offset dish -- whatever the size but as you have said - and elsewhere - i have read , some say no benefit on a larger dish . i have a flat scalar and will compare it when i get the chance -- i bought a DMX741U combination C and k.u. l.n.b. including dielectric plate and conical feed -- from america -- early this summer a flat scalar came as part of that package the DMX741U was rather a dissapoinment to me - for use on a offset dish here in england the C band side was not too bad but was outperformed by the £11.00 pauxis that i got from china -l.o.l. and the K/u part was poor for use on a offset dish --- the feed in the k/u part is designed for prime focus -( flat scalar ) so will only pick up very strong satellites -- and the signal is weakened futher by needing the dielectric plate inserted in order to recieve the C band L and R circular transponders -- that are mostly used for C band-- here --and in Europe i,m sure the DMX741U works well enough for most peoples needs on a large prime focus dish :) poor weather forcast tonight for n.w. england tonight -- i will report my comparison findings - when i can regards nelson.b [/QUOTE]
