Hi Folks, Getting ready to gut a old UHF..."Station Master Style" antenna and put the guts of a Diamond X3200A (think that is it...2/220/440) inside it. Has a pretty large coupling (23 1/4" long) with threaded holes for 1/4" radials (little larger than the Diamond). Should I use the same radial length as the Diamond? Was also going to use a pigtail to get above that coupling...will that hurt much of the signal? It is about 5 1/2" longer than the Diamond. Was going to cut it down some and replace the cap on top with another one. It would be a larger cap since the radome tapers from top to bottom. Suggestions? Wasn't sure if a PVC cap would be substantial enough. Hopefully will have time to get pictures as I go as well. 73, Robert
