Hi everyone,
I'm looking for a little sanity check and/or advice here. I am a volunteer fire fighter in a small valley in British Columbia, Canada and am looking at building a VHF repeater system. The reason for this is that the valley is very long and narrow and for some mind-boggling reason has 4 separate fire departments. Since we have mutual-aid agreements in place, we often end up responding together for many incidents.
Our current dispatch systems are radio/call-out based, and I am putting together a proposal for local government to build a common dispatch in the form of a VHF repeater station patched into a phone line. The valley is lined by mountains, and there is a site that has off-grid power already that is available for use (run by local not-for-profit internet company). This site is about 4000ft above sea level and service areas are more or less between sea level and 300ft elevation. The furthest area for service is about 7.5 miles from the proposed station.
I've done a quick line-of-sight analysis from the proposed repeater station to the fire departments and their service areas, and produced a basic map to visualize it. My request is for confirmation that the distances on the map in the line-of-sight areas will be easy to communicate between repeater station and handheld radios without issue. I don't have any gear picked out, so just assume some pretty basic stuff (open to suggestions). Sorry, the map distances are in metric Map link below.

Thank you,
