Hi Jeff:

I have the F12 620/340 at 75 feet and a 4BA at 85 feet.  I am definitely
seeing interaction between the 40 meter and 15 meter elements.  The
resonance on 15 meters is way low.  F12 recommends 12-15 feet separation.
Some have turned the antennas 90 degrees different with success.  Me - for
now, I just use a tuner.  I may at some point raise/turn the 4BA in the
spring and or shorten the driven element for 15/17 meters.
