LDG RU-4:1 Unun


The RU-4:1 Unun was designed to allow the easy interface of vertical and end-fed antennas to the LDG line of Automatic Antenna Tuners. The 200-watt Unun also operates “stand-alone”, and thus does not require an LDG Tuner for resonant verticals. It may also be used with many of your antenna projects where a 4:1 Unun is needed.
