- Sleeve balun
s are normally used at VHF and higher. As a general rule, they are not practical at HF.

Baluns on Log Periodic Antennas
- Some antenna manufacturers place balun
s at the incorrect location in LPDA arrays, or tell you to route the cable incorrectly. This can cause substantial RFI and all sorts of weird problems like RF into house wiring.
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
