K7MEM Center-Fed Half-Wave Dipole ( 3-30 MHz)
- A Center-Fed Half-Wave Dipole is probably the simplest of antennas to construct and use. It is usually suspended between two supports, from it's end insulators, and has the feedline hanging from the center.
Feeding an End-Fed Antennapop
- 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.

- Connecting centre fed antennas, dipoles, yagis, rhombics, loops to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation resulting in power loss and the radiation characteristics changes
Eliminating TX RF Feedback Problems
- Malfunction of transceivers due to stray RF pickup is a common problem, especially when using end-fed antennas, high-impedance feedlines, or a poor ground counterpoise
