Hi Doug and all,
Yes, this is for ALL of you out there, especially those contemplating a
Diamond antenna. I use one for 2M, 1.25M and 70cM and it works GREAT. At
a height of 50' AAT which BTW is just about AMSL around here (;->) over
flat terrain I get a range of about 100Mi on 2M & 1.25M with about
40-50Mi on 70cM with the average FM station. Of course it gets better
using SSB and repeaters which have better antennas and locations.
OH! The point was the RF connector! (;->) Diamond, like most antennas
also come supplied with a type N connector, choose the correct model
number when ordering. It only makes sense since the military PL-259 "UHF"
connector presents a lumped impedance which can be troublesome on VHF and
UHF. Leave it to the military to call it a UHF connector, right? (;->)
The BNC type which includes the N (an overgrown BNC) is a true coaxial
design and presents a constant impedance of 50-75 Ohms in keeping with
the transmission line employed. Oh, but you knew that...
