The answer that was proposed for one local hospital was to put the whole
mess on a middle floor, with 3dB stick just outside. But because another
cut-throat shop came in and bid a used flexar rptr, and said it would
work just fine on an existing antenna on the roof, they went that way.
Oh, while the rptr was UHF, the antenna they used was a VHF 4-bay. It
was resonant. Didn't work for beans in the hospital, worked good about
10-12 mi away though.
The antenna and rptr have since been replaced, but it still doesn't work
all that well.
