Better yet, wind the coax through multiple cores following my Choke 
Cookbook. Now, from the choke down, you can dress the coax any way you 
like, and the choke prevents signal picked up on the coax from filling

that someone else builds rather than something they can do themselves 
for a fraction of the cost.
