| Below is a
drawing of a fan dipole antenna designed for 4
bands. You should be able to achieve a
match on 4 ham radio bands with near mono band
performance. I was able to tune it with an antenna tuner on all ham
bands With A decent bandwidth. Start with
the longest wire antenna element first, achieve a good
match on it then work your way to the
shortest. The spacing of the wires is
not criticle. You can make spacers from
any insulator.
You can use
a tuner fo all ham radio bands from 40-10 meters, this is
a much better performer than a g5rv antenna or
trap type dipole antenna. Ideally 75 ohm twinlead
would be best but coax will work fine.
I have found
that this antenna out performs all that I
have tryed for swl listening.
The lenghts
below are approximate.
