Why We Picked These Four Products
- The President Walker IV FCC is the newest generation of the legendary Walker line and the direct successor to the Walker III truck CB standard. AM/FM on all 40 channels, President's industry-leading 0.5 µV AM / 0.3 µV FM receiver sensitivity, NOAA weather with weather alert, plus modern additions: Glow Mode, Noise Reduction Circuit, Automatic Squelch Control, VOX, front USB-C charging, and SWR protection. Same classic OEM truck form factor that fits factory cutouts.
- The Stryker SR-A10 antenna is modeled after the U.S. Air Force's Thunderbolt II — 6-gauge solid copper coated in 100% silver plate, capable of handling 10,000 watts. Overbuilt for the Walker IV's 12W AM / 4W FM output, which means it runs cool, efficient, and delivers years of clean signal. Reduces static interference and comes with a 2-year warranty.
- The DRX-3402 mirror mount is built from .250″ aircraft-quality extruded aluminum with a 2.50″ wide double-slotted design. The SR-A10 is a big, heavy antenna — this is the mount that won't flex or fatigue holding it up over a million highway miles. Stainless-steel Square-Lock hardware means one-wrench install and no lost washers.
- The DRX-1518 18-foot M213 coax is ultra-low-loss double-shielded cable that delivers RG213-grade performance in a mobile-friendly diameter. 96% tinned copper braid plus 100% aluminum foil shield means your transmit signal gets from the radio to the antenna, not radiated into your cab wiring.
Buying these four separately, you'd have to match antenna power handling to radio output, verify the coax connector types, confirm the mount slot spacing fits the antenna stud, and figure out cable length for your truck's cab-to-mirror run. We've done that work. This combo drops in as a clean CB install.

DRX-3402 Heavy-Duty Antenna Mirror Mount
The DRX-3402 is a Driver Extreme heavy-duty mount purpose-built for large mobile antennas like the SR-A10. Extra-large 2.50″ wide mount from .250″ aircraft-quality extruded aluminum, with Driver Extreme's exclusive Square-Lock hardware for one-wrench installation. The double-slotted design gives you fitment flexibility across west-coast, standard, and heavy-duty pickup mirror brackets.

DRX-1518 18-Foot M213 Premium Coax Cable
The DRX-1518 is 18 feet of Driver Extreme M213 Quantum-Flex coax — RG213-grade performance in a mobile-install cable diameter. Ultra-low-loss double shielding means the transmit signal your Walker IV makes actually gets to the antenna instead of getting lost as heat in the cable or radiated as noise into your truck's electronics.
Key features: 18-foot length · 50-ohm impedance · Tinned copper braided shield (96% coverage) · Free-floating aluminum foil shield (100% coverage) · Ultra-low signal loss · M213 Quantum-Flex double-shielded construction · Mobile-friendly diameter.
Installation Overview
A typical mobile install on a semi truck runs like this:
- Mount the DRX-3402 to the driver-side or passenger-side mirror bracket using the double-slotted alignment.
- Attach the SR-A10 antenna to the DX239 stud on the mount. Torque per manufacturer spec.
- Route the DRX-1518 coax from the mount, down through the cab body, and into your radio location. Avoid running parallel to power wiring — cross at 90° where possible.
- Connect the coax's PL-259 connector to the Walker IV FCC's SO-239 antenna jack.
- Use the Walker IV's built-in SWR meter to check the install. Adjust the SR-A10's whip length up or down as needed to bring SWR under 1.5:1 on your primary channel (Channel 19 is a good starting point for truckers).
The Walker IV's built-in SWR meter means you don't need a separate meter or bench visit to dial the antenna in — you can tune the install yourself in a truck stop parking lot in about 10 minutes. The Walker IV's SWR protection circuit also safeguards the finals against damage while you're tuning.
Frequently Asked Questions
What's included in this President Walker IV FCC install combo?
This combo includes four products: the President Walker IV FCC 40-channel AM/FM CB radio, the Stryker SR-A10 silver-plated mobile antenna, the DRX-3402 heavy-duty mirror mount, and the DRX-1518 18-foot M213 Quantum-Flex coax cable. Everything you need to complete a mobile antenna install, minus the microphone and external speaker.
How is the Walker IV different from the Walker III?
The Walker IV keeps the classic Walker sound, layout, and OEM truck form factor drivers know, and adds AM/FM operation on all 40 channels, Glow Mode adjustable backlighting, a Noise Reduction Circuit for voice audio, dedicated P-Channels for one-touch access, SWR protection, Automatic Squelch Control, VOX hands-free operation, a front USB-C charging port, and NOAA weather channels with weather alert. Same fit, more capability.
Is the Stryker SR-A10 a good antenna for the Walker IV FCC?
Yes — the SR-A10 is our top recommendation for the Walker IV. It's rated for 10,000 watts, so at CB output levels the antenna is barely working — it stays cool, efficient, and delivers years of reliable transmission. The silver-plated 6-gauge copper coil is one of the most conductive antenna designs available, and the low static profile matters when you're trying to pull in a distant station on Channel 19.
Will the DRX-3402 mount fit my truck's mirror bracket?
The DRX-3402's double-slotted 2.50″ wide design fits the majority of west-coast and standard mirror brackets on Peterbilt, Kenworth, Freightliner, Volvo, Mack, and International trucks. It's also suitable for heavy-duty pickup mirror brackets. If you have a custom or non-standard bracket, contact us with your make/model and we'll confirm fitment.
Why is the DRX-1518 coax 18 feet — is that long enough?
For most truck cab installs, 18 feet is the sweet spot — long enough to route from a mirror-mounted antenna down through the cab body and to a radio mounted in the dash or overhead console, with enough service loop for door movement. If you're running a sleeper cab install with the radio in the bunk area, you may need a longer cable. Contact us if you need a custom length.
What SWR should I expect after installing this combo?
After proper installation and adjustment, you should see SWR of 1.5:1 or better across your primary operating range on the CB band. The SR-A10's whip is adjustable — trim it slightly for higher-frequency operation or lengthen it for lower. The Walker IV's built-in SWR meter lets you tune the install without a separate meter, and its SWR protection circuit safeguards the finals during tuning.
Can I add a microphone and speaker to this combo?
Yes. Many truckers pair this install combo with our DRX-6560 noise-cancelling dynamic microphone and DRX-9010 external speaker for a complete cab audio upgrade. If you want everything in one package instead, see our Walker IV FCC combo with speaker and mic.
Does the Walker IV FCC work on 10-meter frequencies?
No. The Walker IV FCC is a 40-channel CB radio designed for the 27 MHz Citizens Band, not the 10-meter amateur band. For a 10-meter radio, see our Stryker SR-955HPC+ or Stryker SR-655HPC+.
Do I need any additional parts to complete the install?
This combo includes the radio, antenna, mount, and coax. The Walker IV FCC ships with a stock 4-pin dynamic microphone, power cord, mounting bracket, and mic clip — so you can transmit right out of the box. Depending on your specific install, you may also want an upgraded microphone (the DRX-6560 is our recommendation for cab noise) and an external speaker (the DRX-9010 is our top pick for trucks).
Can I use this combo as a base station setup?
The Walker IV FCC and DRX-1518 coax work fine in a base station configuration. However, the SR-A10 and DRX-3402 mirror mount are designed for mobile use. For a base install, you'd want a CB vertical antenna or dipole cut for 27 MHz instead. Contact us if you want to build a base station combo and we'll recommend the right antenna and mount for your location.
