Do you mean F/B on the XM240 or on the 204BA ? At any rate - I doubt if it is a trivial exercise to do so , but I would try the 40 meter antenna at right angles to the 20 meter antenna and see what t

Mark - I had a situation with a HAM- IV where I would get BC imod products on 160 and 80 . I chased myself all over the place looking for rectifying junctions in my antennas. Finally one day I accide
