CB/ General Electronics Help

I just installed a CB radio in my TJ. I mounted to the top of the dashboard in the middle. The placement is sturdy and I hid the wires nicely, but the sun is constantly on it. Is there something I can use to absorb the heat so the radio doesn't overheat or do I even need to be worried about it?

sun visor in the windshield is a cheap solution

In my Escape, I had my CB mounted on the dash, didn't have it covered and mever had a problem...that was in Washington, but I wouldn't expect problems, they're made to withstand it.

I am a ham operator, as far as I can think, as long as you are getting air through the heat sink then everything should be fine. If your really worried about the direct sun maybe knocking out your freq. meter or something, just throw a ball cap or something over it to shade it when not in use.
Hope this helps.

Some of them have wax filled something (capacitor?) in them. At least I think that's what it was. It hit 100 here in Washington and the radio I had mounted in the center of the dash on a Chevy truck left a puddle of wax on the dash. Hard to get off the dash and didn't do the CB a bit of good either. I use one of those sunshade things now.

Check the operating temp. some will survive better than others.

I would GUESS you'll be fine, and if not it should have a heat overload protection circuit before it lets the smoke out.

I would not permanently cover it with anything that will restrict it's ability to dissipate heat while in use. I also wouldn't boost it, but nobody does that anyway, right?
