Ldg ru-4:1 unun balun frequency coverage: 1.8 to 30 mhz, power range: to 200 watts,


The RU-4:1 Unun was designed to allow the easy interface of LDG S9 vertical antennas to the LDG line of Automatic Antenna Tuners. The 200 watt Unun also operates "stand-alone", 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.

Weight: 6 oz (with enclosure),
Configuration: 4:1 Unun,
Frequency Coverage: 1.8 to 30 MHz,
Power Range: to 200 watts,
Easy to weatherproof.
Enclosure size: 5 x 2.5 x 1.25 (measured in inches).
