[Antennas] Antenna Vibration

My long wire (which is attached to the house by an eye bolt screwed into the
woodwork around the 2nd floor window) used to vibrate HORRIBLY any time the
temp dropped below 50 and there was a slight breeze.  Then I changed the way
it was held up at the other end and the problem (thankfully) went away.  The
noise often got so loud it drowned out the tv!
