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.

This meter does not include the jumper coax needed to attach it in-line between the radio and the antenna.   Check out the PP8XX coax as a jumper coax option.

To Calibrate and Check SWR:

1) Set radio on channel 1

2) Set meter to 10W FWD  

3) Set meter to SWR

4) Key microphone and turn dial until meter needle goes over to SET

5) Set meter to 100W REF

6) Record SWR reading

7) Repeat steps 2-6 on channel 40

Once you have your readings, you will make adjustments, as needed, based on those readings to optimize antenna performance and ensure that you won't possibly damage your radio.   Here are some links to our Help Center regarding tuning your antenna:
