I've been using one here with a perimeter of 333 feet for several years now for receiving purposes in the range 160 to 530 kHz. A binocular core with a 1:2 turns ratio at one of the bottom corners provides the step-up to the RG-6U coax to the receiver. I've no problems with static charges or arcs (so far), but I have thought of putting some high value resistors from the loop ends to ground. 73, J.B., VE3EAR - VE3WZL Solar and wind powered Lowfer " EAR" 188.830 EN93dr http://www.hurontel.on.ca/~weazle
