Gentlemen and Dear Ladies, I just bought a Comet CHA 250 vertical multi band HF antenna. It says no radials required. However, I've seen some reviews where a couple of guys added radials anyway. Also, I've seen a couple guys add grounding. Two questions, First, where and how exactly should I add radials to this antenna. Attached to the bracket that mounts the antenna to the Mast? And a ground, how would one go about setting something like that up? Thanks All, C.
