Here's another classic HF antenna worth trying.  In this video, Stan Gibilisco (W1GV) introduces us to the Windom Antenna and explains the theory, design, and operation of this "oldie but goodie" from the early 20th century.  Modern versions of this antenna can be fed with balanced feed line and used with an antenna transmatch (i.e. "tuner") to gain multiband HF operation.

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.

Here's another classic amateur radio antenna you may want to try if you're in an experimental frame of mind.  This antenna is patterned after the HF antennas used on Zeppelin airships during the 1920s and 1930s. Stan Gibilisco (W1GV) does an excellent job of explaining the theory, design, construction, and use of this legacy multiband HF antenna.
