Thanks to all who answered my question on remote tuners. I have MORE than
enough info to go forward.
Everyone have a GREAT Thanksgiving.

Looking for input from the collective knowledge of the reflector.
You have a wire dipole for 75 meters fed with a 1:1/5K rated balun. You want to
transition to a remote tuner so you can move around 75/80 meters.
The question is: Do you leave the balun in place, or remove it and feed the
Hi Bob,
If you are going so far as to removing all the stubs, go one farther. I' ve
heard that the limited High Power problem is because of arc over between the
top of the tower section and the 80m stub mast above it. I've heard several
stories about fireworks at the top of the tower during
How do again Bob,
I forgot to add IF you short the stub at the top then forget about using the
drop wire. Just put the coax feed direct to the bottom of the load coil, and
the top of the coil to the tower base T. Short out the coil for 80m ops. At
least that is where I'd start experimenting.
How do to all.
Glenn is chasing a 160 meter antenna puzzle, where the SWR on a vertical
supported by a 4x4 increases when he touches the top of the 4x4.
First off, the disclaimer: I AM NOT AN ANTENNA GURU!
With that said, Glenn, does the same thing happen when you bring your
finger/hand
How do to all,
I have a hypoth--er hipoth--oh, alright, a theory, question for all. Take a
grounded, 1/4 wave vertical (pick your band/freq of interest) made of tower
sections. You're going to feed it with a gamma match. Could the gamma match rod
go on the inside of the tower sections for

Dan is looking for radial wire.
I've been lucky to find spools on sale at the local Big Box stores. Another
source, again if you watch for sales, is 14-2 awg w/ground NM Romex type cable.
Run an inexpensive Romex splitter over it and you have 750 feet of radials from

Now, do I just use the Pro's III tuner or the Amidon UnUn to
minimize SWR at the feedpoint-

Paul,
You could also try 10 or 12 turns of #12 or 14 gauge wire, 2 diam across the
feed point and ground.
