"Sticking" a CB radio in your vehicle is a no brainer, BUT installing a communication device correctly is a Brainer! There are "rules" that need to be adhered to that'll insure your CB will operate at its best, and last a long time. One aspect of a CB radio "system" can be likened to stereo "systems", whereas very high quality speakers, and cables, will make a low end tuner sound much better then vice versa, hence a high quality Antenna/Coax combo, placed in an optimal location, will greatly enhance the performance of a mediocre radio. Check your area for a reputable CB Shop and discuss antenna choices and options, and get the Antenna and a high quality Coax from the shop that helps ya (the little extra $ you might pay can be viewed as current, and maybe future, "Consultation Fees". If can't find one on your area there's a very good Shop in Carlisle, 2588397,
dtbradio.com. (Check out his site and see what he's about) Dave doesn't do installations, but he can give ya suggestions on the best Antennas for your vehicle/purpose, and after you've installed your Antenna he can check it (hook up a device) to make sure it's good, and check the SWR when your radio is hooked up. Also, not all radios, especially low end, and used, radios, are exactly on frequency so you should have your radio checked, and "tuned" if necessary, so it operates at peck performance.
I know it sounds like a lot of hassle for something you'll most likely only use out on the trail, but why go through all the work and expense installing a CB just to have it perform poorly (i.e., sounding bad or not being heard farther then 200') or end up with a damaged radio that needs replaced?
This is MHO and, as always, your results may vary.
