how to build a high Q low loss counterpoise coil
All,
Reg's counterpoise program predicts the effective ground of a centerloaded
vertical on 75 meters can be improved by a tuned relatively short counterpoise
system. This is dependent on a large, high Q, low loss tuning coil.
After some playing with the numbers a starting point for the design of such a
coil is 200 mm diameter, 200 mm long, with 4 gage wire, and a pitch of about .7.
This is obviously quite large.
My questions a
1. Where is a good tutorial for large coils?
2. Are there coil forms for such coils?
3. What would the impact of a square or octagon be versus round?
4. How critical is spacing toward a high Q?
Thanks,
