A similar antenna, but one step closer to multiband operation
would be a simple dipole for one band (40m) fed with a multiple
of 1/2 wavelengths of ladder-line. At the resonant frequency,
it is hard to tell from a coax-fed dipole and an antenna
tuner will allow coverage of the entire band. The bonus is
that such an antenna can be made to work well on all ham
frequencies above the design frequency. If one is willing
to vary the length of the ladder-line, one can get by
without a conventional antenna tuner. Info at:
