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". ---------- For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://w...

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.

This is post #1054 in a continuing series of Simple Ham Radio Antennas. Here's a handy device that will increase your enjoyment of amateur radio while protecting your HF transceiver from excessive SWR.  SWR protection is particularly important with end-fed half wavelength wire antennas and random length wires used during portable and emergency operations. Kevin Loughin (KIB9RLW) shows us how to design, build, and use a simple, inexpensive L network antenna transmatch (i.e. "tuner") that will enable you to use a variety of random length wire antennas without worrying about excessive SWR or RF feedback in the shack.  The video is well-produced and explains in simple terms how to build this valuable accessory to your ham shack.
