Hello,
Planning to remove the top (145 ft) Force 12 EF240X in the next
several weeks due to a problem that appeared right before
Christmas. The ant. suddenly shifted resonance from 7050 KHz to 7120
KHz. Also, the ant. doesn't seem to work as well even at the new
resonant freq. Nothing can be seen obviously wrong with the ant.
looking at it from the ground and at the top of the tower with
binoculars. Any ideas on what the problem could be?
73,
Mike, K4GMH
