- JA7KPI Windom antenna for 40-80
- The total length of this antenna is 41m, height is about 11m, and diameter of element is 2mm.
JA7KPI modified this antenna originally used as Inverted-V type of 80m band Dipole.
Works on 40 - 80 meters band with acceptable swr.

- 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
dipoles.

- The EZ-Tuner
- The "EZ-Tuner" is a homebrew automatic legal-limit antenna tuner that covers all amateur HF bands from 160-10 meters. Using a T-network design and controlled by a BASIC Stamp BS2sx microcontroller, the EZ-Tuner will match at least a 16:1 VSWR for either unbalanced or balanced transmission lines.

- Windom Antenna with 4:1 balun
- The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
