The key to effective performance in a long wire or random length end fed wire antenna is the proper matching of the high impedance of the antenna to the low impedance of your HF rig. In this video from "Signal Search", we learn how the Palomar Engineers Multi-Ratio Cube Unun makes the impedance match possible. This unun, joined with with an external antenna "tuner" and a decent ground radial or counterpoise system, allows you to use a single wire as a multiband HF antenna. "Signal Search" shows us how the unun helps maximize antenna performance, while reducing RFI and SWR issues.
