[Motorola] Practical Range for CM200/CP200 Radios

[Steve Ponder - N5WBI]

We recently purchased a Motorola system that consists
of 1 CM200 mobile radio (146-174 MHz, 25-45 Watts,
4-channels) and 6 CP200 hand-held radios (146-174 MHz,
1-5 Watts, 4-channels).

The CM200 came with a mag-mount 1/4-Wave VHF antenna.
Each of the CP200's came with a VHF Heliflex NAD6502_R
antenna.

The primary channel on which we will be operating is
151.625 MHz.

What average range should we expect for:

[1]  Mobile to hand-held transmissions?
[2]  Hand-held to hand-held transmissions?

What would be a "better" antenna to use for the
CM200 mobile radio?

Thanks for your help!
