[Elecraft] Dual Receivers 2 different antennas Diversity receive

[donovanf at starpower.net]

60 feet of antenna separation does not provide diversity capability. 
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.

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.
