If you have 60 ohms then you have a good impedance, and that's about 
what I would expect from your configuration.  I don't know how you did 
the wiring to the PL259.  Did you mean an SO239?  Regardless, it sounds 
like it may be an insulation problem, getting water or bird poop on the 
connections then arcing over.  When that starts the thing will burn up.  
The other possibility is a poor solder job on a PL259 or getting water 
into the PL259.

I don't think a wire from top of the tower to ground will make any 
difference.
