Since 700 and 800mhz are a much shorter wavelength than say the 42mhz frequincies they are much more line of sight which in turn makes them more affected by terrain.

I have a magmount antenna on a hunk of sheet metal in my home "shack", and I get about 30 miles on 700 and 20 miles on 800. In the truck, with the same kind of antenna on the roof, I get 60 miles depending on terrain on both bands.

That's pretty good. I think my best was 20 miles on 800 but then again it depends on terrain, hills and tower locations. I haven't monitored any police or fire depts. on trunking or digital trunking systems yet.
depending on the coax and condition of it, any splices, connectors, could affect the signal strength. and an antenna could be in a blind spot for the signal.
