Topband: Low Dipoles

[donovanf at erols.com]

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.
