Fire ground repeater ( at 854) has worked better than the 859 freq. My observation is that using the normal input frequency affects portable unit communication,. New Haven had a chance a long time ago to have a first class 800 MHz trunking system with 3 sites... East Rock, West Rock, and K of C building, but blew it. PD, FD, Public Works, would have portable coverage city and beyond that wide. And that means in building portable coverage. But as it stands, well, I am surprised the unions of the respective departments have not complained.
