Would it be possible to have a system of antennas like this?:

  • Antenna 1 is built for Band 1 and has a filter with a passband that includes Band 1's frequencies.
  • Antenna 2 is built for Band 2 and has a filter with a passband that includes Band 2's frequencies.

It'd be kind of like a trap on the feedline. 🤔

There are many variations of this. If you have separate feedlines, this would be what most contest and mult-operator stations use. There are also e.g. triplexers that allow you to use three radios (10/15/20m) on a common triband antenna. See e.g. https://va6am.com/ for some examples.

You should use a diplexer instead, containing a high and a low pass filter.
