"Reg Edwards" wrote in message ... Lee, Using the loop indoors, at ground-floor level, at 20MHz, on a groundwave path, is not inconsistent with what you get. Get it high-up, outdoors, and it will make a big difference. Next, after testing 2` above ground....... The capacitor is made from a length of coax. I wonder how long it is and how it is located relative to the loop? Wherever it is, being unbalanced coax it will unbalance the loop. Isn`t a variable butterfly vane capacitor unbalanced also as is the co-axial trimpot and the compression piston cap?..they are all used on magloops Reg. But what worries me, the very thin coaxial inner conductor is in series with the main loop conductor. It may have a loss resistance several times greater than the large diameter main loop. You could be losing a lot of decibels. I`m listening Lee....G6ZSG..... |
