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 73 Frank W3LPL ----- Original Message ----- From: "Jim Brown" <[email protected]> To: [email protected] Sent: Saturday, December 12, 2020 10:55:47 AM Subject: Re: Topband: Low Dipoles On 12/12/2020 2:53 AM, Jim Brown wrote: > I fully agree with observations that DX can arrive at higher angles. 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. 73, Jim K9YC _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
