Horizontally polarized receiving antennas should be very low, so that
they discriminate very effectively against both local vertically polarized
RFI as well as atmospheric noise propagated via the ionosphere at low
angles. They can occasionally work very well near sunrise when
high angle DX signals are most likely to occur.
I've never found them to be more effective receiving antennas than
Beverages or arrays of short verticals at sunset or at any time during
the night

I should have added that low dipoles can be better RX antennas for high
angle arrivals, since efficiency doesn't matter on RX, but it matters a
LOT on TX.
