The common bicon balun (the traditional long-neck variety) may explain the
differences encountered between V & H. If my feeble memory is correct, the
balun is only marginally "balanced". Consequently, it could be sensitive
to cable length and routing. (An easy test for imbalance would be to sl
minor variations with polarizations and geometries" where
geometries is understood to mean test distances.
