Let's take a look at the End Fed Random Wire antenna. Specifically the X-Tenna version. Similar to a End Fed Half Wave but intentionally NOT resonant on any amateur radio band, it requires an antenna matching unit to use. Through the antenna matching unit, the EFRW can be used on all HF amateur radio bands but practically, for the lower bands, you do need a longer radiating element.
Best lengths for an End Fed Random Wire antenna:
26, 29, 41,52 ,58, 71,& 119 feet
7.92, 8.83, 12.49, 15.84, 17.67, 21.64, & 36.27 meters
