How To Repair Cb Antenna Cable
Shorts in your coax cable will prevent your CB installation from working properly. While they aren't likewise common, it's important to make sure your coax isn't defective when troubleshooting. To test your coax for shorts, you lot need to be familiar with testing electrical resistance. If you're not, please refer to our guide on Understanding Electrical Resistance before reading further.
Footstep 1
Examination the ground portion (the outside butt) of the coax for resistance, every bit seen in Paradigm 1. Make sure to touch both probes firmly to the metal butt. At that place should exist no or little resistance, indicating continuity of the cable. Make sure to test both your primary coax cablevision also equally the jumper cablevision used to hook upwards your SWR meter when tuning your antenna. If y'all measure complete resistance, there is a curt in the cable, and you'll demand to replace it.

Step 2
Examination the inside portion (the middle pin) of the coax for resistance, as seen in Image 2. Make sure to touch both probes firmly against the heart pin. There should be no or little resistance, indicating continuity of the cable. Make sure to test both your master coax cablevision as well as the jumper cablevision used to hook upwards your SWR meter when tuning your antenna. If you lot mensurate complete resistance, in that location is a curt in the cable, and you'll need to supercede information technology.

Step 3
Test for consummate resistance beyond the ground and hot lines. To exercise this, touch i probe to the "hot" eye pin on one side of the coax and bear upon the other probe to the "ground" barrel connector on the other side of the coax. There should exist complete resistance, indicating that in that location is no continuity betwixt the hot and basis lines. Make certain to do this for both your primary coax and the SWR meter'south jumper cable. If yous discover continuity between the hot and ground lines of the coax, at that place is a short in the cable, and yous'll need to supplant it.
