Good morning. I would like to experiment with making a high Q coil for creating
a tuned radial counterpoise. Reg's program predicts a coil of about 70 uH will
create a match. One way to create such a coil would be to wind coax and use the
shield as the conductor. Besides the obvious loss of physical stability due to
lack of a form what are the limitations or drawbacks from using the shield?
