Brett, No one can answer that question for you, because both antennas are unpredictable in nearfield performance. Also the layout of the antenna and what is around, under, and between the antennas is very important.
With such a large soup of unknowns, plus there might be other transmitters on site (?), the only way to really know is to try it. If you had a normal dipole and wanted interaction to a vertical of known efficiency I have all that data. One thing I learned is minimum coupling from a good dipole to a good vertical was with the dipole BROADSIDE to the vertical, not at right angles as I assumed without thinking. The problem is the Carolina Windom is nothing like a dipole and not nearly as predictable as a dipole for nearfield or close farfield coupling, and that goes on top of the other variables that are bad enough on their own. Maybe you should go to an antenna forum, like on eHam or QRZ, armed with the information of the safe signal level the K3 will tolerate. Other than the safe signal level, this is really an antenna theory question and a good answer would be too complex for a radio reflector. 73 Tom - Original Message ----- From: "Brett Howard" <[email protected]> To: "elecraft" <[email protected]> Sent: Thursday, June 24, 2010 5:14 AM Subject: [Elecraft] Antenna Separation for Diversity > So I know I'm going to shoot for as wide as I can get things...
