Angel,
Actually it addresses link coupled tuners that with a tuned to resonance
using a balanced tank circuit. You can feed balanced lines from taps
placed equally out from center on the both coils. The center of the two
coils is common (ground), and unbalanced loads can be fed between the

I am probably the last person in the world to comment on this but in my. very
limited experience as a ham I have found resonant dipoles to be superior to a
G5RV. I have used properly cut dipoles that I made myself for 20m and 40m and
they worked much better than the G5RV I had. You may want to
I use a G5RV mainly on MARS freqs. From 3.2 MHz to 30 MHz using the k3 and
internal ATU with great success. Never found a frequency it would not easily
tune.

Hi there--
Am considering putting up a g5rv
I started off with a normal G5RV and the tuner handled it fine. But, it works
better as an all band antenna with the tuner if you do what I did and eliminate
the matching section (which only matches 20M's) and replace it with ladder or
window line down to a balun or at least a current choke
I was using a G5RV but noticed that it performed poorly on 10 and 15m. I
switched to a nonresonant dipole of similar overall length, fed with 450
Ohm ladder line, which works noticeably better on 10 and 15m (I think this
is due to loss from the 50' of coax I had been using to feed the G5RV).

I have used a number of G5RVs, both with and without balun. I carry one in
my 'go-kit' because it goes up quickly and comes down easily. I have used
duel band dipoles too but found them harder to get set up properly. The
spacers would tend to get snagged in trees and made them harder to coil up

That's because they're fighting each other! [duel vs. dual, :-)]
I use a six-band resonant dipole for my (portable) operation. That's the
best thing I've found in 33 years of experimenting. But my version works
I do not have a G5RV, but I do have a Mystery Antenna that is
similar. They both have a stub line made of ladder line. The problem
with the ladder line is that it radiates RF so you must must must get it
away from anything susceptible to RF. Mine is not far enough away from
the shack and I
If you have access to some space (I hide my antenna in the HOA 'common area'
trees, no one looks up or even uses that area), then what I use may be of
interest to you.

They do :-) Another way to feed dipoles cut for different bands using a
single feeder which I find to be less fussy, is to configure the dipoles as
Coupled Resonators, with the feeder connected to only one of the dipoles -
usually to the dipole cut for the lowest frequency band. The dipole
Another style 80/40m dipole was made using a 3-inch spacer of nylon
rope to disconnect the outer part the 80m dipole from the center 40m
dipole. A plain old alligator clip was used switch bands. Unclip
for 40m and reconnect for 80m...Makes a great portable antenna for two

I'm not surprised Bob. The best way is to throw the G5RV away or feed it
with balanced feed - 450 ohm twin or open wire to a balanced atu.
The design of the 5RV is a compromise. The twin section acts as a
transformer and will only present the correct match at certain
frequencies if the
