Like the lower freqs. 42.000 have longer distance in range. Is the monitoring range less on these other trunking digital freqs?
Typical range for monitoring on 700 to 800 freqs?

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.

That's probaby why I can't monitor long range in those upper freqs. unlike the lower freqs which I enjoy more because of the distance.
Depends on lots of variables. Transmission height and power are two of the biggest factors.

The most distance on 800 I received was about 19 miles on Scant Antenna or ChannelMaster antenna.
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.

Isn't that kind of monitoring range considered exceptional? Or out of the norm?
I guess so, but as the cliché goes, your mileage may vary. Just telling you what I can get.

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.

coax
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.
