Subject: Topband: 5/8 wavelength vertical is mo betta than shorterversions??
In the early 90's N6KB and I tried a 5/8 wl Vertical on 160m.
It was a wire vertical supported by a helium balloon and spaced several
hundred feet from a permanent 1/4 wl Vertical.
Both antennas had a similar, extensive radial system and they were both over
average ground.
We did many A/B comparisons during that contest weekend.
We were shocked to find that the existing 1/4 wl performed better than the
much taller Vertical.
This was around 1992 so we did not model anything but actually tried it.
After this the 5/8 antenna was never tried again.
Recently I have been having some toughts about again trying a 5/8 vertical
just for the fun of doing it.
Actually I am thinking about setting up a few Vertical antennas of different
sizes,
maybe four of them and do a comparison of their actual performance over very
good ground.
They would be sized from a 5/8 wl vertical down to a short whip.
All of them would be set up about 1/2 mile or so out over the Ocean.
I already have a permanent 60' tall bottom loaded vertical there.
I am not interested in making contacts, just receiving signal reports.
Nothing permanent, this would be a one time deal.
I am wondering if there is any interest in participating in this.
Any Suggestions are welcome.
