An SWR meter is an essential tool for installing a CB radio and antenna. It allows you to tune your antenna, which is adjusting the length of the antenna for optimum performance. This not only gives you the best range but it can also prevent damage to your radio.


In the event the Test Center does not perform to your expectations:


       1. Make Sure all cables are connected properly.

       2. If meter needle sticks or if you take your thumb and rub it accross the meter and the follows it, use a staticide spray on the meter face cover. (An anti-static spray from Amazon or local electronics store should work fine)
