[Elecraft] K3 Ant 1 and Ant 2 Isolation?

[Rich]

During FD we were discussing portable antenna options for next year.   
We were considering a 33' fiberglass pole with a veritical and a G5RV on 
the same pole.  A 31' piece on wire running vertically down the pole and 
also a G5RV supported by that same pole.  Then just connect them to the 
K3 Ant 1 and 2 jacks and away we go, however should we expect to flood 
the Ant jack which is not in use with RF due to the antennas being so 
close?

Any thoughts?
