[TowerTalk] 6btv

[Jim Jarvis]

The Hygain verticals are interesting.  I've had a couple of
them, at various times.  The bases are particularly good for
making single band verticals with.

I had a 6btv set up as a GP, on top of a 50' pushup mast
once.  Discovered that replacing the trapped antenna with
33' of straight aluminum tube was worth something >3dB on 
40 meters.  (Groundwave measurement of a nearby ham's signals,
determined by varying his output power to produce the same
S meter reading in both cases, and measuring the power
difference in his bird wattmeter.)

I've compared an R7000 against a full sized elevated GP on 
40 meters, in an honest A/B comparison.   The differences
were small.  Never measured the R8, but it ought to be as
good or better than the R7k.
