Random length end-fed antennas are simple, effective HF antennas if you calculate the proper wire length, use a wide-ranging antenna transmatch (i.e. "tuner"), and employ a proper  counterpose system. Mike Markowski (AB3AP) does an excellent job of explaining both the theory and practice behind random length end-fed antennas.  If you're in an experimental mood, you may want to try the 1936 end-fed "zepp" antenna from H.
