I assume the tubing is very well connected at the joints? Copper tube? Yes! What type of capacitor? How are the connections made? Variable airspaced 12-14kv rotary supplied as a kit by local radio company --£18.50p--- Turning the loop horizontal won't help unless you can get it up 1/4 to1/2 wave or more. I already said that! :-) Close to earth you are better off with vertical, and the mat will help efficiency although it is pretty deep for higher bands. !!!.... 73 Tom Thanks Tom. 73.

How do they keep current out of pressure contacts? Why did you only make it 3 feet diameter, because you wanted to use higher bands like ten meters? How are the connections made? You know of course even the physical size of the cap (if physically large) can greatly affect loop efficiency. It's nearly impossible to make a small loop work like most people predict. Lots of things can be problems. 73 Tom |
