I want needinfo on the type of cores do I need to use with RG58 and RG 214
to make a choke type BALUN at 2m. I am building a vertical dipole out of 1
inch al tubing. coax will pass through the bottom half othe dipole with the
sheild fastend at the middle of the bottom piece and cneter conductor
fastened to the top piece of al. Initial test indicate I have RF on the
shield and need some decoupling. Winding the coax into a coil certainly
helped but this has prevented me from placing the antenna in a fiberglass
tube the way I had planned.

Thanks all, found what I was looking for at Wireman.
