Ham Radio - Build your own L network antenna tuner. Post 2134.

Thanks to Kevin Loughnin (KB9RLW) for this remarkably simple, inexpensive L network antenna "tuner" for long wire and random length HF antennas. Coupled with a good ground radial / couterpoise system, this easily made "tuner" will allow multiband HF performance from a single end-fed wire antenna.

Here are some observations from Kevin:

"They're really very simple to build. I over-built this one to make it clear for the video, but you could make it smaller, put it in a nice box with labels and paint. ;-) I did just that in a newer video. https://www.youtube.com/watch?v=9-fuQ... The antenna I had connected for the demo is an external 98 foot (29.87 meters) end fed wire".
