UHF power - constant or switched? Your thoughts???
Hey all,
I got my new GME TX4500 yesterday and looking to install it today, what's your thoughts/advice on ignition power vs constant power?
I don't have dual batteries yet but if I go with constant power I'd switch it to the second battery afterwards.
I'm thinking ignition power makes sense but wondered if any of you guys have done it that way and regretted it?

I run mine off accessory power, means I can have the UHF on without having the ignition on. If I put it on constant power I would forget about it and flatten the battery.

SUCH IS LIFE
Same as Tony, wired mine of accessories power for peace of mind. I would have flattened my battery 100's of times by now.
You're always in the car or next to it when using the UHF so the key is most probably in anyways

I hooked mine up using constant power supply, and yep have left mine on over night a few times, but lucky 4 me haven't managed 2 flatten the batt yet.
If I was doing another install, I would just run it off ACC. No real benefit of having constant power 2 it

Mines hooked up to the accessory circuit, turn the keys off and the thing switches off.
You probably could hook it up to be constantly powered as long as your truck is used frequently(mine sits in the shed for a week at a time, so no good to me)at least then there would be more chance of not leaving it on long enough to drain your battery.
Better to wait for some advice from the auto sparkys here they will have a much better idea about current draw etc.

I am he, fear me
Wire it so it is switched thru Accessories.
You can "power" it from wherever you want if you put a relay in and energise the relay from the ACC .
Some will say wire it permanently but other than being able to turn the set on if you don't have the Car Keys I don't see the point

I like mine powered permanently, on the tracks its allways on even if the acc / car radio is off for what ever reason.
Doing a recovery its working even if Ive turned everything else off. Same at camp if waiting for a late arrival or whatever.
Its the way I prefer it.

My UHF currently only runs when the ignition is on, and is a pain in the ass. When I fitted my radios in the overhead roof console, I used the OE wiring which was already fitted (and powered) in the hood of the Patrol for the electric sunroof, the problem with this is that they are only powered when the ignition is on as I said. I'll probably change it to run on the accessories setting sometime down the track.

Thanks guys, yeah I meant ACC power.
Looks like that is the way to go, I've got a couple of handhelds for other times.

The most common installation would be to an accessory feed, but it really doesn't matter, it's totally up to you.
But the biggest killer of a cranking battery is continually running it flat.
