There is one brand of LNB's that are circular polorized that I have used
that mounts directly to the old lmb feed horn where the 7 bolts are.
and I have removed the old lna and put a regular LMB neck on the V slot
where the old feed horm was and clamped down with a strap across the
neck of the LMB and two mounting screws. both worked ok and the signal
gathering power of the greater size is really notiable. I keep mine low just
four feet off the ground so I can brush off the snow during bad weather
while I am experimenting wiwth other KU sats. There is a pro job for this
that I have used ideas from .
