If you use a "long" or "random length" wire for your HF antenna, you'll probably need a simple antenna transmatch (i.e. "tuner") to reduce SWR and RFI caused by the mismatch between your antenna and your transceiver.
In this well-produced video, Kevin Loughin (KB9RLW) takes us step-by-step in the design, construction, and use of a simple L tuner for random length wire antennas. This basic impedance transformer can be used at home and for field operations. Views expressed in this video are those of KB9RLW.
