[TowerTalk] VHF/UHF Ant's - Misc Questions

[KB7WW Art Moe]

Jim,
What is the loss in your high power diplexer???  and what coax 
are you using??? and how much???

What I am trying to get to is, is the loss in db worth the dollars 
not spent???

If this club is going to put up long boom Yagies for vhf & uhf in 
the horizontal plane it sounds like they are looking for weak signal
performance, not extra losses.
