Setting Antenna SWR: Part One

Your antenna system's standing wave ratio (SWR) is one of the most critical parts to pay attention to for your radio system as it measures how efficient your antenna radiates the available power from the radio. In this series, we will explain how to set up your SWR system for maximum efficiency.  

To start off, you will need: a properly installed antenna system including the mount, coax, and antenna; a radio, a SWR meter, and a jumper cable with PL-259 connectors. Make sure your vehicle is in an open area with all doors closed. For the actual set up, first make sure to disconnect the coaxial cable from the radio if it is connected. Then connect that cable to the SWR meter in the part marked “Antenna”.  

Now take the jumper cable and connect one end to the radio and the other end to the SWR meter’s “Transmitter” or “Xmit”. Your SWR meter should now be in line with the radio and antenna, make sure your system is in AM mode and tune your system into the lowest channel available to your system.
