Antenna Balun and UnunBalun Construction. Baluns are devices to balance unbalanced systems.
- Simple HF Baluns for 50/75 ohm coax
- Show diagrams, winding methods and tables of some 1:1 and 4:1 baluns for 1.8 - 30 MHz suitable for use up to 200W (400W peak) on systems using 50 or 75 ohm coaxial cable input where SWR should not exceed 1.6:1.

- Sleeve Baluns
- Sleeve baluns are normally used at VHF and higher. As a general rule, they are not practical at HF.
The balun can be inverted and used as a skirt to form part of the antenna element

- Transmitting Baluns
- One of the most popular Ham-lore rumors is a balun's performance can be tested or evaluated by grabbing the coax and watching for an SWR change. This is probably one of the worse test-rumors circulating

- Tuner Baluns on Input
- There is a common perception that placing a balun on the input of a tuner causes the balun to work better. The thought is the balun operates with a matched impedance and that reduces balun losses. It also is thought that moving the balun improves balance.
