What JM says is quite true. However without a thorough understanding of basic antenna theory you will only be lucky once in a while. The term non-resonate or un-tuned is a misnomer. All antennas have to match the impedance of the XMTR at the operating frequency. If not cut to frequency, there are many devices to match the antenna, from a large "Tenna Tuner" which was in the 26-D's, to a bed spring from the old army bunks -- basically 600 ohms. I carried two store bought items in the field. A 100 foot roll of insulated single strand copper wire for my antenna and a small battery operated Field Strength/SWR meter which fit in my shirt pocket. I got them from Radio Shack when Radio Shack actually sold radio supplies.

Non_resonant antennas filled the dumps with hundreds of burned out KWM-2's.

BTW: I am speaking of the time when we still carried the AN/GRC-109 to the field. The 100 ft. wire was specific to the 109. My point remains, pay close attention when radio/antenna theory is taught (presuming it still is).
