LDG Electronics Baluns, UNUNs and Chokes
LDG Electronics RU-9:1 Unun
LDG Electronics RU-9:1 Unun was designed to allow easy interface of random length vertical and end fed antennas to the LDG line of Automatic Antenna Tuners. This 200 watt Unun also operates as a standalone, meaning that it does not necessarily require a tuner for use on a certain antenna. It may be used with many of your antenna projects where a 4:1 Unun is typically recommended. This model is small and easy to weatherproof for use in the elements. LDG RU-9:1 Unun specs: * Ratio: 9:1 * Frequency coverage: 1.8 to 30 MHz. * Power range: Up to 200 watts PEP * Enclosure dimensions (WHD): 2.5 x 5 x 1.25 in. * Weight: 6 oz.

LDG Electronics QRP Pixie Balun Set
The LDG Electronics QRP Pixie Balun Set was developed for QRP Enthusiasts and is a compact solution for matching and experimenting with a variety of antenna systems. Designed for up to 10 watts, this set includes two professionally built transformers: • Transformer 1: Balanced/Unbalanced, Converts from BNC to parallel wire (~500 Ohms) • Transformer 2: Balanced/Balanced, Converts from 500-Ohm parallel to 5000-Ohm parallel Made from thick, high-quality materials, both boards are ideal for portable use and field experimentation. Whether you're setting up a dipole antenna directly behind the first 10:1 balun or feeding a more distant antenna via twin-lead and the second 10:1 Bal/Bal transformer, this kit offers flexibility. Helpful construction tips and suggested wire lengths are printed on the back of each board—making them a perfect companion for weekend projects or lightweight SOTA/POTA operations.
