Random Length Wire Antennas can be a lot of fun to use if you have a sturdy balun and decent ground radial or counterpoise system to control SWR and stray RF in your shack. In this video, Paul (OM0ET) shows us how to design and build a 9:1 UnUn for this versatile antenna. The balun uses a T 130-26 toroid from an old PC Power Supply. The original design comes from VK6YSF (https://vk6ysf.com/unun_9-1_v2.htm).
In part 2, Paul will test the final antenna design and balun on his Xiegu X5105 transceiver running only 5 watts output.
