I found a table of radio frequencies (UK-based) including the amateur range around 50MHz and Air/Civil bands above 110MHz. Only for temporary DX'ing. Recently bought an old book "Art of Electronics" with hundreds of AM/SSB etc. receiver circuits (want to construct some). Aviation enthusiast so 135MHz is also our "air" band.
Here are some things to consider:
If receiving only through an antenna, resonance is not required. I would build a dipole, or a
ground-plane antenna for the lowest frequency, and then just use it as-is at a frequency up to 3X higher...
Antenna polarization is much more important than resonance. In the US, most of the signals on six meters (50MHz) will be horizontally polarized (horizontal antenna elements), while the aircraft band (118 to 137 MHz) and the ham and commercial FM radio signals above 144 MHz will be vertically polarized (vertical antennas). Dipoles work best for horizontal polarization. Sounds like two antennas in your future...
For transmitting at two or more frequencies, you can build two dipoles, one resonant at say 120MHZ, another resonant at say 150Mhz, connect their feed points in parallel, put the two dipoles in divergent orientations ( a few degrees apart in space), and the two antennas will not interact much.
(fan dipole). This saves running two coax feedlines.
The best all-around vertically-polarized broad-band VHF antenna is a
Discone. I am using one here as a test antenna. It can be used for transmitting or receiving with a VSWR less than 1.5:1 over the range of 100MHz to 1.5GHz.
