What is the best way to power a 12-volt radio for 30 - 60 minutes
before requiring a re-charge? (solution must be re-chargeable via auto
adapter)
We are wanting to use an actual CPE radio with a 19dBi panel
antenna, connected to an iPAQ/Axim so we are needing a re-chargeable
power source for the
We use the 18V DeWalt Flashlights and take the head off. Put a Cat5
plug on it where the flashlight head was, and you can inject power into
the devices. Be sure to use a volt meter because on the one I had, Red
was negative, and Black was positive.
If you make a Cisco Reverse PoE cable, you can
So 18vdc *should not* damage a 12vdc radio?
Any idea on how long an 18vdc DeWalt battery pack will
power a 12vdc radio?

1 hr??? We use them for a site-survey and are done... I know they last
more than 20 minutes.
Don't know what kind of devices you are using, but Tranzeos, CB3s, and
Mikrotik (all what we use for clients) support 12-22VDC. Then the
Motorola is supposed to be 24V, but 18V still powers it.

We use 18volt Bosch batteries from our cordless drills to temporarily power
cpe's for sight surveys. Not sure how long they would last under continuous
use. We use them because they are part of our tool supply and are always
charged.

Mac,
We believe this is truly an outside offender in 2.4 GHz. I have
personally seen a carrier that is several times more power than anything
I have ever seen. I only saw it for a brief instant though. This
interference just does not last long enough to be caught. The
I use a 100 watt inverter that plugs right into the cigarette lighter power
port. May not power the laptop (haven't tested) but the CPE will stay on
for much longer for an hour.
