I should have clarified 540 feet of separation on 160 meters, much less on higher bands (e.g. 280 feet on 80, 140 feet on 40)

Diversity depends on independent fading of received signals, accomplished by at least one wavelength of spacing between two identically polarized antennas or by two antennas with opposite polarization. More than one wavelength of spacing will provide even better diversity performance. One wavelength of spacing requires 540 feet of spacing, almost ten times more what you're proposing to use. 73 Frank W3LPL ----- Original Message ----- From: "VernonJ" <[email protected]> To: [email protected] Sent: Tuesday, January 28, 2020 7:27:31 PM Subject: [Elecraft] Dual Receivers 2 different antennas Diversity receive My K3S has Main and Sub receivers. I would like to use Diversity receive with the Main using the transmit antenna, and my Sub using a small receive loop. Is there sufficient isolation on the Receive Only antenna connection to protect the Sub? Antennas are 60 feet apart, and I intend to run 500 watts at some point. If I need additional isolation and protection, how would I do this? Thanks. -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
