A "Random Wire" antenna is an end-fed antenna that is operated against ground or an artificial ground system - much like a vertical antenna. The "Random Wire" must normally be coupled to the transmitter by an ATU (except if it happens to be in resonance on some amateur band).
A popular length is 7m. This does not provide excessive impedances for the ATU to tune out for bands between 80 and 10m.
