Antennas : 17M
- Extended Double Zepp Antenna for 17 m
- 17 meters band version of an extended double zepp antenna.
The Zepp, short for Zeppelin is any resonant antenna end-fed by ladder line. A Double Zepp means a center-fed antenna. This extended version provides 3 db gain over a dipole. The double Zepp consists of two collinear 0.64 wave length elements fed in phase

- Build your own 20m vertical
pop
- Build your own 50ohm coax fed 20m vertical antenna, so easy a 9 year old can do it, or at least help! And the budget? You may already have the materials on hand, or worse case spend $15 by Andrew Daniel - KI4QFY

- 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-fed dipole.
This article will introduce the Half-Extended Double Zepp (HEDZ) which has characteristics that a lot of amateur radio operators should find quite interesting

- 50MHz J-Pole Antenna
pop
- Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

- 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.

- There are many incorrect ideas and claims surrounding end-fed vertical antennas (like the I-Max 2000), end fed horizontal antennas, Zepp, and J-pole antennas. This article describes it.
[Hits: 6581 | Votes: 3 | Rate: 8.67] - End-Fed Halfwave Antenna
pop
- 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
