[time-nuts] T'bolt antenna lead-in running near HF RF transmitting coax

[EWKehren at aol.com]

In the past when I had that problem I used copper pipes as feed through the 
 wall and bend the pipes with a pipe bender one on each side. Never had a  
problem, do not know if I would have other wise.

I've run  my GPS antenna lead along with coax carrying 100 Watts on HF and 
50 watts on  VHF / UHF with no known issues.

I do have ferrite chokes on all my feed  lines.

I also use the Symmetrciom 53532 antenna.
