This winter I have been working on the design and construction of a
compact loop for 80 meters. The loop will be constructed from 72 ft of 3/4
in copper pipe and will be in the shape of an octagon. The plane of the
loop will be vertical, and the loop will be remotely tuned by a vacuum
variable capacitor coupled to a geared stepper motor.

I have just finished constructing and testing the driver for the stepper
motor. See
http://tinyurl.com/bwobb for pictures and some information about the
system. Constructive comments will be appreciated.

John, how high above ground is the antenna?
