President Johnny III USA + Stryker SR-A10 Truck Install Combo
Pair the President Johnny III USA with a threaded Stryker SR-A10 antenna, Driver Extreme DRX-3402 mirror mount, and DRX-1518 M213 coax. This combo is for a suitable mirror-mounted CB installation, not a magnetic-base antenna setup.
The included Johnny III USA is a 40-channel AM CB radio for 12- or 24-volt vehicle systems. It features NOAA weather reception and alerts, manual squelch and ASC, RF gain, channel scan, VOX, and an orange, green, or blue display. It does not provide FM or SSB operation.

Check the vehicle installation
Verify that the mirror support can accommodate the DRX-3402 and carry the antenna assembly. The threaded SR-A10 uses a 3/8-24 antenna connection; this is not the SR-A10 magnetic-mount version.
The 49-inch measurement describes the whip, not the complete mounted antenna height. Allow for the antenna base and mounting position when checking overhead clearance, and provide an appropriate RF ground connection at the mounting location.
Route the coax without pinching or crushing it. Its 18-foot length provides cable routing length; it does not mean the antenna is already tuned for your vehicle.
External SWR check
The Johnny III USA does not have a built-in SWR meter. Use a separate external meter and suitable connection cable to check and adjust the installed CB antenna system before regular operation.
Don't forget to add the Pro tune and alignment option at checkout so that your radio is professionally bench-tuned for best performance per the manufacturer's service manual.

Frequently asked questions
Is this the magnetic-mount SR-A10?
No. The package contains the threaded SR-A10 antenna and a separate DRX-3402 mirror mount.
How much coax is included?
The DRX-1518 is an 18-foot M213 coax cable with PL-259 connectors.
Does the mount fit every truck?
No universal fit is promised. Check your mirror support's dimensions, mounting access, strength, and grounding arrangement.
Does the radio have a built-in SWR meter?
No. Use a separate external SWR meter to check the completed antenna installation. The radio's display includes an S-meter for signal strength.
Is the mounted antenna only 49 inches tall?
No. That figure is the whip length. The antenna base and mounting position add to the complete installed height.
Is a DIGIMIKE or BT MIKE included?
No. This truck package includes the radio's standard microphone. DIGIMIKE and BT MIKE are offered in their own separate combos.
