If you have a good way to support a vertical dipole and a good way to
pull the coax feedline away from the antenna at 90 degrees the dipole
is much simpler to install and feed and will perform the same or
better than and end-fed vertical.
>Has anyone had on air experience with both types of antennas??
I have. I've put up several of both. I'll take the dipole if I have a
big tree handy. The verticals go up on open real estate where they
usually have to be ground mounted. Beyond that there are no
Right now I have a 20m dipole strung from the top of a tree, the
bottom end is around ten feet off the ground. It works fine as an
antenna, I can work just about any dx I can hear with a barefoot xcvr
and I can hear just about any signal the guys with the beams in this
area are hearing. But I would not call it a competitive antenna on
20m, ya gotta work to get thru the cw pileups. Any tribander at 50 ft
will spank it. The big downside is that the thing is a noise magnet. I
also have a 475 ft horizontal end-fed wire strung thru the trees at
around 40-50 ft. When I tune a weak signal with the agc / s-meter on
and switch back and forth between the two antennas the noise level
with the vertical is a full s-unit higher than I have with the
longwire and the longwire gives me a little less than an s-unit of
gain. That's 10 or so dB or almost two s-units more noise with the
vertical. It would probably be a lot worse than that if I was in
southern climes like Florida where there is a lot of qrn.
