RANDOM WIRE ANTENNA with 9:1 UnUn home made (part 1). Post 1764.

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.
