I would really appreciate any input/suggestions on the need for a CMC. First of all, I have a Zero-Five 43ft HF vertical that includes an Un-Un. I purchased a CMC from MyAntennas.com and was wondering if there was any need for this with the antenna I'm using. Is this choke better suited for a wire antenna or is there a better place to install it other than right at the antenna? Thanks for any help!
