I have been following this thread with great interest. I'm curious how many
of the guys who have responded have ever built and/or used a 1/2 wave
vertical,,, other than me.....
One guy said:""1/2 wave vertical won't show any gain over a quarter wave
vertical unless it has a much larger
radial system"".... First of all a 1/2 wave vertical is a voltage fed
antenna therefore it doesn't want/need or like a radial system. The current
portion is 1/4 wave above the feedpoint. Because the 1/2 wave vertical is a
1/2 wavelength it will automatically have gain over a 1/4 wave vertical.
There were several comments about the """"horrible/terrible"""" noise a
vertical hears and they are useless for receiving. Those guys obviously
weren't following my DXing activities this winter 75 meter DX season. 95% of
the time my 1/4 vert outheard my 1/2 wave dipole, at 1/4 wave high. The only
time the dipole heard better was when there was exclusively high angle
propagation. The only guys, out west, who regularly beat me were the guys
with multiple element yagi antennas and much much much higher power than my
100w.
To 'sort-of' answer AA5JG's original question I will go heads up against any
2 ele 40 meter yagi against a 40 meter 1/2 vertical at the 100w power level.
It has been my '''on-the-air''' experience the 1/2 wave vertical will beat
the 2 el yagi 90% of the time, working DX. John if you have extra money
laying around there is a very good performing loaded 1/2 wave vertical
antenna made by hy-gain. I used one for a couple of years, before it took a
direct lightening hit. It was mounted 12 feet above the ground. You will
work a lot of DX with it. You won't be the first guy through a DX pileup but
you will be a long, long, way from the last guy using that antenna.

Subject: [TowerTalk] Vertical vs Beam
I have a question for the group about experiences with different antennas:
I was looking at a recent issue of CQ at the local bookstore tonight (it
wasn't the April issue) and in a column dealing with semi stealth antennas,
they mentioned that a 3/8 or 1/2 vertical will show comparable performance
to a 2 element yagi. Is this true? Will such a vertical really do as good
as a 2 element beam?
Also, how would a roof mounted 1/4 wave vertical compare to a 2 element
tribander at a low height-like 25 feet or so?
