I have a 40 ft vertical fed with coax that I am using today on 60 meters
with excellent results. I have 34 radials under it now at about 43 ft.
I am wondering how I can use this antenna on other bands? 40, 20, 17, 15,
12, and 10 meters.
I am sure if I wanted to put it on 75m I would need to install a cap hat,
and don't think I want to go through that but would like to see how I could
use it else where?
Appreciate the help.
Scott,
On frequencies higher than 20-meters I doubt you not will be please
with performance above 20-meters for a 40-foot vertical - unless you
are primarily interested in talking to airplanes - as most of your
power will be launched at high angles.
I have a nice dual-band (40/20-meter) vertical described on my web
site at
http://k6mhe.com/files/DualBandVert.pdf which you may find of
interest.
