Tom,

That means that RF is coming down your coax lines from your antennas, 
and that you have a long ground wire which will radiate that Rf.  You 
also could be having a ground loop between your electrical and RF ground 
rod.

I would try a coax RF choke at each antenna and or connecting a second 
ground wire that is a few feet longer which should lower your RF ground 
reactance.
