Hi Joe,
Thanks for the email. I figured I was just looking at a way to improve it. If
it does reduce noise some, then it was worth it.

Good Evening John
I would ask you after using your antenna system for 14 years with good
results why are you considering adding a coax choke? Are you having a problem
with RF in the shack? Are you having a noise problem that you did not have
before? To answer your question if there is RF coming back down the shield coax
choke may help reduce this. As to the noise if it is being caused by the first
problem then fixing the first problem should help with problem #2.
The reason I ask this is I have had the same coax, feed line, balun, and HF
antenna now for about 9 years. It also works very well and always has.
I look at it like this. If it ain't broke don't try to fix it. Now if you are
trying to improve on the system then You may get some different answers. This
is JMHO. Good luck and let us know how you make out.

Subject: [TowerTalk] G5RV balun question
I have a homebrew G5RV type antenna. The antenna wire is fed with 300 ohm
radio shack twin lead, which runs to a Van Gorden HI-Q 4:1 balun, which then
feeds RG-11 75ohm coax. I have used this system for 14 years now with good
results. I am wonder if adding a coax choke balun (several turns of coax wound
up in a circle) would help at all. I would like to minimize RF on the shield of
the coax (as well as noise it would pick up) and think the HI-Q balun should do
this, but would the coax choke help as well, or just be redundant?
