40-80 Half-Extended Double Zepp Antenna
- A dual-bander for 80M and 40m. An Extended Double Zepp (EDZ) is a 5/4 wavelength center-feddipole.
This article will introduce the Half-Extended Double Zepp (HEDZ) which has characteristics that a lot of amateur radio operators should find quite interesting
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.
An improved 40-80 double extended zepp
- Article originally published in ARRL compendium by N6LF revisits the classic double extended Zepp to improve pattern and SWR bandwidth.
The DEZepp is essentially two end-fed collinear

- This type of antenna has same performance as a dipole, but requires only one single mounting point
End-Fed Halfwave Antenna
- The end-fed halfwave antenna is a resonant half wavelength long antenna like a dipole antenna except for it is fed at its end rather then in the center. This antenna is as old as radio and is probably best known as the Zepp Antenna
- 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
Ni4L ANTENNAS & ELECTRONICS
