A beam or wire antenna of half wave or less CAN build up a static charge 
enough to do real damage to a radio left connected without protection. 
You need to continually discharge the antenna across the gap in the 
dipole, by resistive bleeders to earth.  150 K ohms, (150,000) from each 
side, will look like an open circuit to RF going to a tuned dipole 
element, but will keep charge from accumulating upon the elements and 
discharging through the front end of the receiver.
Have seen this discharge using a neon bulb that fired at 65 volts, right 
across the end of my feeder.
