Well I did a power test on 446mhz on 50'..
Testing at the radio I got 23watts
Testing at the other end I get 13w
I am loosing 10w through coax loss....
Is this excessive or something normal?
This is the coax

Friend has this 40/80 antenna and I am a bit confused on how to feed this thing.
The coax just plugs in to it there is no unun or balun on the end or a way to attach a counterpoise.
Hope this link works..
