[Lowfer] vertical

NOT. My 45' vertical has the ends of the 72' flattop about 25 or 30' off the
ground. It is buried in the trees and still makes an occasional 1,304-mile
trip.

Now if that dang horizontal loop would have worked...

Bill,

If drooping top hat radials reduce the antenna's effective height NC has
been running a 25 foot antenna all season.  Think I should remove the 6
drooping wires and go for a full 15 meter antenna?
