The RBA-4:1 Voltage Balun was designed to allow easy interface of ladder line antennas and long wires to the LDG line of Automatic Antenna Tuners. The Balun operates "stand alone", thus does not require an LDG Tuner. It may be used with any of your long, random, or ladder line antenna projects
4:1 Voltage Balun
This ratio transforms impedance by a factor of four. It is typically used for antennas that have a higher feed point impedance, around 200 ohms.
- Best for: Folded Dipoles, Off-Centre Fed Dipoles (OCFD), and certain Loop antennas (like a full-wave Delta Loop).
- Types: For most ham applications, a 4:1 Current balun is preferred for its superior balance (the LDG RBA-4 is a Voltage Balun)
