A complete CB antenna system with all the parts needed to get you up and running. This kit consists of a fiberglass CB antenna, 4-bolt mirror mount, and 12 feet of coax cable. Just add a radio along with this kit and you'll have everything you need for a complete CB system

Tuning Procedure:
1. Check your SWR on channels 1 and 40.
2. If channel 40 is higher than 1, lower the antenna
3. To lower, remove the cap from the top of the antenna, and use a knife to trim back the insulation until you see the copper wire.
4. Pull out the copper wire (it will unwind from the antenna). Cut around 2" to start with with a pair of cutters.
5. Put the antenna cap back on, and re-check your SWR.

As long as channel 40 has a higher SWR reading than channel 1, keep removing copper wire.

When you're finished, channels 1 and 40 should have roughly the same SWR reading, and channel 20 should have your lowest reading.
