An external 4:1 balun is typically less lossy than the built in 4:1 baluns. Better still, use the W5YR idea, a bead ferrite choke on the coax output, then connect there with a coax to binding post adapter for balanced line, and you eliminate questions about your balun.
An alternate is to use a coax cable choke on a plastic Coke bottle, (liter bottle) for form. -Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
