CB Radio Switch

Hey all. So I'm going to be installing a CB in my JK, but I really only plan on using it offroad. Because of this I plan to totally remove it when I'm using my Jeep on road (prevents theft too). So I'm planning in installing a quick disconnect at the radio to be able to unplug it easily. But I was thinking it's not a great idea to have power flowing to the disconnect terminals when nothing is connected to it. So, I thought I should maybe switch the power leading to it. That way I can run power right from the battery to the switch then to the CB power.

My question is do I really need to switch that power to prevent problems? And if so, do I need a relay for that or can I just add an inline switch to the hot line.

Thanks all.

First, power does not flow if there is no electrical connection between the source and load. Sure, the potential is there when disconnected, but no current flow. You could just cover the disconnect when your CB is not in use.

Or, install one of these as I did:
Quadratec JK-APT2011 - 12 Volt Power Adapter for 99-16 Jeep® Wrangler TJ, JK , TJ Unlimited & Wrangler Unlimited JK - Quadratec

Works like a champ.

Use a two conductor trailer connector to make the power connection. Connect the + side of the Jeep power to the female side of the plug that will remain in the Jeep and you won't have to worry about covering it. They only cost $2-3 and they're bulletproof. Any trailer supply store will carry them, I've even seen them for sale in Lowes and Home Depot.

In the below photo, the left-half would connect into the Jeep, the right-half would be connected to the CB. That way nothing has to be covered and there's no danger of anything touching the hot side of the plug connected to the Jeep when it's disconnected.

Thanks @RuDawg7890 , understood on the power flow, but I think I want to connect directly to the battery.

@Jerry Bransford , that's exactly what I was planning to use but I still thougth there could be exposure to the hot connection even if using the left side connector in your pic on the power (Jeep) side. That's why I was thinking switch. Maybe I'm overreacting. As I said above, I want to go directly to battery so there is exposure even when the Jeep is not running.

I've been an electrical/electronic guy since the 60's, there's no need for a switch. Don't overthink this, it's a simple thing you're doing.

You convinced me. One more question? If I go right to battery with the power, are there wires I can buy that have a fuse built in (power side) and the ring termial already attached? Or am I stuck with having to build my own splicing in the fuse and ring terminal connector.

Thanks for your help.

I use these for quick-disconnect connections in the Jeep ....

Waterproof Electrical Connector Plug

Haven't had any issues with these so far (about 2 years)

Pretty much any store like Fry's Electronics, Radio Shack, any CB or ham radio store, and usually even Lowe's and Home Depot will have prewired in-line fuses for sale.

Like this


Or this

Yeah I was think you would have to crimp on a terminal, but splice in the quick connects you choose.
There are ones like this for specific radio's connection types:
Heavy Duty Fused Battery Cable Power Cord Kit for High Output Radios

But you'll spend a lot less DIY.

This is what I have in mine. ^^^

Much appreciated all. I don't think I'll be spending $89 on that HD cable, so I'll build my own. I'm not bad with electrical connections, I just don't understand the whole wattage/amperage stuff. I just have to find a local place to get supplies like a Radio Shack or even an auto parts store.

I used a 2-pin MOLEX connector I picked up at the local electrical supply store for a few bucks. It works the same as the trailer connector described in previous posts and has a positive locking feature. I added the ferrite core behind it for noise suppression - my radio is really old and needs all the help it can get!

I had an unused switch on my sPod so I connected my CB and PA speaker on that switch. I can turn the power on when then Jeep is not running too. Just throwing it out there.

Using the Quadratec CB quick disconnect mount I am able to unscrew 2 butterfly bolts and disconnect all the wiring for easy removal, takes less then 1 minute to have the CB in you hand.

Why do you have a second on-off switch for your CB?

I know this isn't exactly what you are looking for but why don't you just use a cigarette lighter plug since you want this to be removable anyway. Then it's fused through the outlet.

It is poor installation practice to power any 2-way radio like a CB from a cigarette lighter receptacle. It's always recommended to power them directly from the battery (via the Power Distribution Center's input power lug at its rear) due to that being the most noise-free source of power in the Jeep. Other sources can pick up alternator or fuel pump whine, static, etc.

I completely agree in most cases. But he wants to communicate to a group of off roaders that are 30 feet away from him on the trail and isn't planning on making it a permanent install. It would most likely work just fine. If he was dropping in a Yaesu and trying to maintain contact with weak stations half way across the world that would be a different thing.

Don't have plans for that switch so figured I'd put it to use rather then having a dead switch

I don't make recommendations for what will just 'get by'. Claiming someone is only going to be communicating 30' and thus doesn't need good power still wouldn't make me recommend anything but clean power for the CB. No one wants to have to listen to someone talking on their CB with static or whining noises in the background.

I installed my first 2-way radio nearly 50 years ago and have a pretty good idea by now what works well and what doesn't work well. My philosophy is if it's worth installing, it's worth installing correctly. He was given a good recommendation for wiring it properly that met his need that it be quickly removable, no further shortcuts needed.

Well ok then. Thank you for correcting me. I didn't realize that Nikola Tesla was a member here. Still a little sore about that whole Marconi thing?
