[TowerTalk] N Connectors

True enough!  All our stuff had no more than 2:1 VSWR, which really helped
everything survive.  That's hard to accomplish on the low-bands... 160
especially. 

I run a 500' horizontal loop and an inverted L on all HF bands (being
antenna restricted sucks!) and I try not to think about the voltages
associated with the mismatches I have.  So far, so good!

73,

Errrr...Is there such a thing as a mil spec dipole?<:-))  Actually 
running at the band edges on 160 and 75 with the accompanying high SWR, 
the voltage gets pretty high.

Well, it might depend on how you use them too<:-))
