Probably 2.5GHz. 2.5MHz should/would go hundreds (if not thousands) of miles at 100 watts.
A local 145.12MHz amateur repeater that uses 50 watts and a omni reaches ~100 miles away (to a 1/4 wave car mounted antenna), and probably further with a directional on the client/mobile/station. And there are HF QRP people that use low power (10W or lower) and still makes long distant contacts.
