Topband: Oak Rodge Radio Vactrols

[AMDX]

  I ordered some several months ago, it took awhile but I did get them. 
At the time the sender was out of town.

  I just got up a rotatable Flag with a vactrol termination. It works 
great!!  I'm using it for the AM broadcast band. Adjustment of the vactrol
often eliminates the audio from stations on the back side. Early tests show
the null is skewed 10 to 30 degrees, some of this could be a chain link
fence near the antenna or another fixed Flag about 70 feet away.
  I'm very pleased with the operation of the Flag antenna. I put up a
fixed flag earlier and thought it worked but couldn't really tell 
because I couldn't compare front to back.

  P.S. If you plan to make a rotatable flag, do it right the first time ;-0
PVC doesn't cut it. Make sure you have a good way to lift the monster
into place. I used a tight rope between two trees with a pulley to lift=
the antenna. The second attempt I realigned and tightened the rope (after
replacing the bent mast) :-)
