I picked up an IMAX 2000 the other day "scratch and dent" basically shipping damage to fiberglass which was easily rectified. Admittedly I am by no means an electronic or antenna whiz but while checking out unit after repairs I checked the masts end to end with my meter and continuity tester and discovered NO continuity from center pin of SO-239 to end of primary mast. Nor was there any continuity from base to end of secondary mast. I didn't even mess with the final mast. This was done...
