- HF Home made Balun
- A balun is a device that is used at the feedpoint of a balanced antenna when an unbalanced feedline is desired to feed the antenna. Balun is a contraction for BALanced to UNbalanced.

- When and Where to Use Baluns
- Baluns are usually used by Hams to feed dipole antennas with 50 ohm coax and to transpose from ladder line feeding a multi-band antenna to the unbalanced input of an antenna tuner.

- 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.
