This is a very nice CB in a small package. It installed under the dash and did not get in the way. Do not be misled by the compact size and low price. The final output power of the Uniden Pro520xl is four watts, the maximum allowed by the FCC for CB radios. All CB radios are rated at a maximum four watts, including the larger more expensive models. With the larger more expensive radios you only get more features, such as analog meters and fancy lights that you cannot see while driving anyway. The trade off is that the larger radios are much more difficult to install in late model cars, SUVs and trucks.The pro 520xl features subdued modern styling and does not look like a left over from the 1970s. The controls are conviently located and easy to use while driving. A draw back, however, was the short microphone cord that took some getting used to. If you buy this or any other CB radio, do not use a "cel-phone" style glass mounted antenna. The glue on antennas look good but are very poor performers without exception. If you must use a glass mounted antenna, do not key up the microphone. The high SWR and electrical inefficiency may very well damage your new radio.The Uniden Pro520xl, hooked up to a properly installed three foot Firestick II antenna had a 1.5:1 SWR on channels 1, 20 and 40 right out of the box. If you want to find out just how useful a CB radio can be on vacation or during the morning commute, purchase the Pro520xl.

I have trusted various versions of the PRO 520 over the years, and the current radio is excellent. Stay AWAY from FM and get this. Use it's R F Gain instead of the squelch. The transmit and receive audio is excellent. Hint: It receives actual signals so if you pick up bad noise, it's a dimmer, touch lamp, power lines, or such. Fix the noise or put the RF Gain down. A long solid CB antenna makes an immense difference. Home or mobile, this 520 doesn't disappoint. Don't get the 510. The extra few bucks are worth it. Don't get an FM junky.

Quit working after four months of use.
