Kim, I once had a KT34XA, and it wanted to couple with anything in the 
air near it. If I had it turned so its elements were parallel another 
antenna, it would always affect swr...sometimes severely. I gave up 
trying to hang a dipole off the same tower because of that. I don't know 
your situation, but if you have other antennas it may couple with, try 
turning the KT34 while monitoring the SWR.
