The best, all round, antenna is undoubtably an approx quarter-wave
vertical antenna, or an Inverted-L, on the lowest frequency of
interest, with a modest set of a few buried ground radials. An
antenna tuner is needed for higher frequencies..

The next best. almost as good, is an approx half-wave dipole at the
lowest frequency of interest, fed with openwire line, where no ground
system is needed. An antenna tuner is still needed for higher
frequencies.
