I recall that hams have a band around 1.2GHz.
Though I've been a ham licensee continuously since high school (never mind what year that was)...
propagation losses at 1.2GHz would be a bit onerous, for a low cost/small system. Just a bit more than at 868 (EU) and 902-928MHz (US) and 918-928MHz (AUS), unlicensed.
