• The Battle Creek Special Antenna - This antenna is often mentioned as secret weapon for LF bands (160, 80 & 40 m) operating at many DXpeditions. It is not commercially available but may be loaned to the expedition staff. It was brought to Ham Radio scene by George Guerin, K8GG, Charlie Dewey, W0CD and George Taft, W8UVZ

• Feeding an End-Fed Antenna - End-Fed antennas are NOT balanced systems; but neither are verticals, ground planes, discones, windoms, zepps, Marconis, half-slopers, et al. Additionally, the low-impedance antenna port of your transmitter/receiver is not balanced.

• Choke balun - Essentially, a choke balun is designed to 'divorce' your antenna from the feed line. if your feed line is coaxial cable then you don't want it to be part of your antenna. you want to be able to deliver all your power to the radiator itself, i.e. 'the antenna'. a choke balun does this admirably
