Greets,

I've never quite understood radios, so I need your help. I need a few (4-?) to use indoors in a building that has a lot of walls. Right now the cheapo radios don't cut it.

Ideally something with enough puch to go through half a kilometer of walls.

Ideal budget 100-150 per.

Considering UHF Lintons, but would VHF be better?

Thanks!

EDIT: Relays not an option, needs to be self contained.
