I hadn't read that. All the info I have on the digital phones just says
"200 mWatt."

When I had bag phone customers report ba reception with the phone on the
seat, I told them to just move it to the dashboard. That seemed to solve
the problems. I've also found that the little magnetic antennas that
fasten to the portable phone's antenna help considerably, but they only
work on skinny metal antennas like on Nokia's or some Panasonics, but
not on the plastic coated ones like Motorola's.

That's fine if your mobile communication needs are for a car phone. Most
of my customers use their cell phones while they're out of their cars at
least a third of the time, often more. One solution I push is the 3 watt
"docking port" for the Motorola phones. Just place any standard Motorola
portable into it, and it's a hands-free kit, battery charger, and 3 watt
booster. While your phone is in the car, you have a full-power car
phone with a "real" antenna. But when you get to where you're going, you
can remove the portable and still communicate.
In the past year, I've had dozens of bag and car phone users approach me
about trading their equipment in for a portable, but no portable user
has ever wanted to switch to a bag or built-in.
One other point around this part of the country. The "weaker" 3 dB
antennas work a lot better than the more "powerful" 5 dB units. The 5's
send the signal out in a very flat pattern, which usually just drives
the signals into the sides of the nearby hills. The 3's radiate in more
of a spherical pattern, which is better for coping with all of our
hills.
SC> -GE> to is it's 3 watts of power. With digital, that advantage
SC> -GE> is moot.
SC> Can you clarify that last statement? I don't quite understand what you're
SC> trying to tell me.
I was told by the BANM techies that digital towers were set up for
dealing with nothing but portables with 200 mWatts of power. If any
vendor ever builds a digital car phone, it will still be a 200 mWatt
phone. I suppose there would be an advantage to a 200 mwatt digital / 3
Watt analog hybrid phone, but on one is building one that I know of.
