What's the best way to listen?

[MountainGirl]

Seeking advice and product recommendations for a radio set-up.

We do not want or need to transmit, only listen to the mayhem post SHTF, on as many frequencies as might be out there.

There is a good high spot 100' from the cabin, with an unlimited view for 270-degrees (there's higher mountains behind us) to set up an antenna(s).

All thoughts welcome and very much appreciated.
