I am thinking of adding a coiled coax common-mode choke to my system. Presently it goes K3-KPA500-KAT500 then 100 ft coax to the base of an inverted Vee¹s center support pole (collapsible fiberglass), then 30 feet up the pole to a 1:1 balun feeding a fanned 10-15-20 Vee. The idea, for a couple of reasons, is to put the choke at the base of the pole, something I haven¹t seen discussed in the literature. Two questions I am wondering about: 1. The choke would be 100 feet from the tuner and about 25 feet from the antenna/balun. Probably not as good as having it right at the Vee, but is that compromise worth while? 2. For appearance sake I am thinking about winding the coax around the base of the support pole. It is 2 inches in diameter but I could slip a 3 inch PVC over that section to increase the diameter. Anyone know an algorithm for determining the number of turns in the winding if I do that? I would be much obliged for any thoughts and suggestions . . . Tnx!
