Hello TTs, As some of you may recall, I'm in the process of shunt feeding my shorty tower for 80/160. On top of this tower is a Cushcraft XM240. Some have suggested that I may need to ground the refl
Kelly, I shorted the reflector of my XM240 when I initially installed it. This was after I noticed no difference between shorted and unshorted. Characteristics seem to be very close to what CC publis
