The LDG Electronics RU-49:1 200 Watt Unun makes it easy to connect vertical and end-fed antennas to the LDG line of Automatic Antenna Tuners and other antenna projects where a 49:1 Unun is required. This 200 Watt Unun may not require the use of a tuner for some resonant antenna wire lengths.
Learn how to build a 49:1 un-un transformer for matching 50 ohm input to 2500 ohm end fed antenna. Follow the step-by-step instructions, parts list, photos and tips for this project by Gordon Gibby.
The RU-49:1 Unun was designed to allow easy interface of end-fed or long-wire 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 lenghts of wire.

LDG RU-49:1 Unun Designed For Long-wire And End-fed Antennas, The RU-49:1 Unun was designed to allow easy interface of long-wire 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 loads.
LDG RU 49:1 Ideal for making your own multiband End Fed Half Wave (EFHW) antenna. Just add wire! 49:1 UNUN 200W. Configuration: 49:1 Unun; Frequency Coverage: 1.8 to 30 MHz. Power Range: to 200 watts PEP; Easy to weatherproof; Enclosure size: 5 x 2.5 x 1.25 (measured in inches) Weight: 6 oz (with enclosure).
An impedance transformer (49:1) to feed a high impedance, end fed (unbalanced) random wire which is likely to be a few hundred ohms, and transform it into something closer to a 50Ω (unbalanced) coaxial input.
