Err, ahh, and how much loss do these things have?  The ones we used in the
Navy were terrible - and they were tuneable so could be 'optimized'.  They
were only valuable because aboard ship we could run lots of UHF transcievers
into one antenna and it worked ok when you were only talking a few miles.
But for amateur purposes they would suck - unless you only want to work your
local repeaters.  But this is not the FM repeater reflector...
