Description:
CB radio antenna suitable for both cars and trucks, compatible with any CB
radio. Very easy to install with the cable and mount in the package.
Installation:
• Connect the CB antenna and the mount with the butterfly screw.
• Attach the antenna-mount assembly to a fixed bracket (eg PNI L1, PNI
SPA110, PNI SPA100, etc.) previously mounted on the car.
• Connect the cable from the package to the mount.
• Connect the PL259 plug from the package to the cable.
• Connect the PL259 plug to a CB radio.
• Test the SWR in an open area using a reflectometer. In some cases it may
be necessary to raise or shorten the wire to get an optimal SWR value.
For maximum performance it is recommended that this procedure, called
calibration, be performed by authorized personnel with special equipment.
