I would like to get my antenna mounted and CB mounted and powered up. Do you HVAE to test SWR before you can use your CB?

Thanks.

Hell, no, it's yours, do whatever you want. Is it a good idea, of course. It's interesting to see how far it's off with the meter when you first install it, but it still works. Unless you're trying to order a pizza from Sicily with it, it will likely be fine. It'll usually reach a mile just fine without ant tweeking.

Do you like burning out your CB? Yes, use a SWR meter. That's why adjustable antenna are popular for CB's, like Firestik, etc.

The efficiency will be considerably lower, you may have horrible howling feedback on your transmitted signal, you may have no discernible transmitted signal.

Tune the antenna/feedline to the radio/setup.

don't forget to use the magic length cable that's been blessed by Kyle.

Best length is one that reaches the main unit. Firestik wants to sell you an 18', but it took a full 20' to reach mine, which is routed from the front bumper (passenger side corner) to under the driver's seat.

And to address the original question: Yes, an SWR meter is needed. Try broadcasting for a while with an out of whack SWR and see how toasty your CB gets. Ain't pretty. The SWR meters from Radio Shack come with some pretty good instructions.

So true! I had all kinds of transmission/recieving issues when mine came up 18" short...
