Default a tuned counterpoise system question

Thanks,

The input to Reg's program is:
F 4 MHz
H 1 M
L 3.3 M
D 25 mm
A 98
B 70
R .7
G 40

This yields 3.2 Ohms input impedance. The coil can be made from PVC and
12 gage wire, the rod, wire, can be 1 inch copper tubing.

Reg's c_poise
program predicts a reasonable set of parameters, a 10 foot 'wire tube',
one meter up, and a coil in the range of 50 uH. The program predicts a
'ground' in the range of 5 Ohms.

How oversimplified is this?


Hi Dan,

You don't include enough information to say. Certainly you can
provide us with the cogent details entered into Reggie's program,
couldn't you?
