Howdy Mike:
I think you have the best solution already. We did the same thing in our
nuclear power plant when we added them to our trunked 800 Mhz system.
Andrew's Radiax throughout the plant's corridors linked via yagis to the
nearest site. Provides good coverage inside the plant, even the lead lined
Containment bldg; although we installed some mobile antennas in the rafters
there and a little bit of radiax below. It's the only thing I've ever h
eard of that really works! You will need active amps here and there as
required by coverage.
