Ham Radio - Build your own L network antenna tuner. Post #1152.

If you can't view the video, please enter this title URL into your browser search box:

Here's a simple, easy to build, and low cost L network antenna "tuner" that will maximize the performance of a random wire antenna.  Kevin Loughin (KB9RLW) shows us how to use locally available materials to design, build, and use this useful tool for antenna designers.  Kevin's instructions are clear and easy to understand.  Add to this "tuner" a ground radial or counterpoise system and you will have a high performing portable multiband HF antenna.  You may want to enclose this "tuner" in a small metal box to protect it from the weather and to reduce RFI to a minimum.
