Simple Ham Radio Antennas--QRO Balun 9:1 Unun for Sloper Antenna Long Wire. Post #981.


If you're having trouble viewing this video, please insert this title link into your browser searchbox: https://www.youtube.com/watch?v=OYhhm2cIHiM. Here's little device that will make your HF long wire or sloper antenna work much better, while saving the finals in your rig from excessively high SWR.  In this short, concise, well-made video, Victory Ivanoff demonstrates how one of his 9:1 Ununs can help you maximize the performance of a long wire or sloper antenna. You'll also need an antenna transmatch (i.e. "tuner") and a good radial or counterpoise system to keep efficiency high and protect your rig from damaging rf currents in the shack.
