[Motorola] Practical Range for CM200/CP200 Radios

[don israel]

That's true. It will look like a shortened, base-loaded 1/4 wave on 6 
meters.  However, you may want to re-check it on 6 meters because the 
frequency to which it is tuned on 2 meters may not necessarily result in 
it's being a sufficiently low SWR on 6 meters.  Just my .02 worth.

Gents:

      FWIW:  The Larson 5/8 WL 2M Koolrod antenna also works quite well on 
6M without mods.  I have one on my car from which I operate both bands from 
one antenna.  I use a duplexer from COMET to mix the HF/6M and 2M 
connectors' outputs from the rig into the one antenna.  Not a bad solution 
if you are operating a Mitrek _1 and _3 in the same vehicle.

I would find a 5/8 wave antenna.  Larson makes good ones.  Cut the whip to
the recommended length and check SWR.  Also, Is the radio 25 watts?  Or 45?
Makes a big difference.

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!
