[Elecraft] Diversity receive and isolating antennas

[George A. Thornton]

I am planning to use my dual receive K3 for field day and we want to try
out diversity receive.  

 

This particular setup will be for 20 meters only.  The primary antenna
will be a 20 meter monoband Yagi mounted on a 40-60 ft. tower.  

 

We were considering using a Buddipole mounted in vertical position and
tuned for 20 meters voice to serve as a Rx only antenna for the sub.
All transmission will be from the Yagi.  I was planning to hook the
Buddipole into a Rx only connector.

 

We will do the best we can to isolate the two antennas but having not
been to the site before I am not sure what will be possible in the way
of geographic isolation.

 

I want to make sure I won't do any damage to the K3 in case the
isolation is not sufficient.

 

Anyone familiar with this situation able to give me some guidance?
