I tested my system again today with better antennas.  Maybe 2 miles of reliable 
functionality.  I need 3 miles.  That is a half roll of fiber.  

I am starting to lean away from radio remote control.  I presume there are some 
cloud based switches that I could use?  Just drop my cell phone into a box with 
the hotspot turned on.  A local cloud based relay can then be controlled from 
another cell phone at the other end?  

Does any of the unifi stuff provide this functionality?

Chances are pushing won't have the coverage you want. I still on a passing 
system and we used to have hundreds of transmitters. Now we have maybe 10. 

Why don't you get a higher power mobile and file for an itinerant  license? 
Digital radios normally have some i/o capability built in as well.

I know they won't be as cheap as the $30  BF junk though. At least some of that 
gear isn't FCC certified. 

For a guy that likes to roll his own there are a lot of options.

  They used to make pagers with a relay in them.  Are pagers still a thing?

    Using Baofeng and Retevis VHF murs frequencies with DTMF control.
    Not terribly happy with the range.  It is only reliable for 2-3 miles at 
most.  
    Going to get some 5/8ths wave mag mount for the vehicle but not sure that 
is going to help all that much.

    Could try UHF but I doubt it will be much better.  

    Anyone know of a radio switch type of thing that works will cell phones?
