Unun on 13m (43′) vertical
Multi band antennas are compromises more so than most mono-band antennas, and part of that compromise is lower efficiency. Often the lower efficiency aspect is accepted without understanding. Last update: 21st February, 2016, 5:16 PM
An inexpensive medium power tuner current balun for HF using Jaycar parts
This is a project to design and build a Guanella 1:1 (current) balun suited for up to 100W on HF with wire antennas and an ATU. For use with a tuner, the most important design criteria are: high voltage withstand; high common mode impedance; power handling. Last update: 11th March, 2024, 7:03 AM
