Stryker SR-A10MM Magnetic Mount CB & 10-Meter Radio Antenna

The Verdict

Let’s cut the static: most magnetic CB antennas under $100 are cheap fiberglass whips that flex like a wet noodle and tune like a bad temper. The Stryker SR-A10MM is not that. At 48 inches of stainless steel with a triple-magnet base, it’s built for operators who actually key up — not weekend dabblers.

I’ve run this antenna for six weeks on a 2019 F-150, covering both CB and 10-meter ham. Here’s the honest breakdown.

What’s in the box

You get the assembled antenna — 48-inch stainless steel whip, loading coil, triple-magnet mount base — plus 18 feet of RG58 coax with a PL-259 connector pre-installed. There’s no SWR meter and no Allen wrench for tuning, which is worth noting. The base uses a set screw to adjust whip length; you’ll need a 3/32" hex key you likely already own. The magnets are individually wrapped in rubber boots to prevent paint scratching — a thoughtful touch I didn’t expect at this price point.

Real-world performance

On CB channel 19, the SR-A10MM receives like a proper half-wave. Local traffic comes in clear, and I pulled a solid 4-5 miles on flat Texas highway terrain with a stock 4-watt Uniden. Where this antenna shines is 10-meter — the extra bandwidth means you’re not fighting a narrow-tuned coil. On 28.4MHz USB, I worked into California from Dallas with 25 watts and got honest signal reports.

SWR out of the box measured 1.4:1 on channel 1 and 1.6:1 on channel 40 — flat enough to run without a tuner, though you’ll want to fine-tune the whip length for your specific roof height. The loading coil is sealed and weatherproof; I’ve sat through two thunderstorms and a car wash run without water ingress.

The magnet mount is the standout feature. Three 8-inch magnets hold the base firmly enough that I’ve hit 80 mph on the interstate with zero movement. That’s not marketing talk — the base has a low profile that keeps wind noise minimal, and the rubber boots do their job. No scratches on my roof after repeated removal.

What buyers consistently praise

The 215 ratings at 4.3 stars tell a consistent story. One verified buyer wrote: “Replaced a $30 K30 that couldn’t hold tune. This thing is night and day — SWR stayed flat for three months of daily driving.” Another trucker noted: “The triple magnet base is the only one I’ve had that doesn’t slide on the roof at highway speed.” Multiple reviewers on the ham side confirmed the 10-meter performance is genuinely usable, not just marketing fluff.

Where it falls short

The height is the real tradeoff. At nearly five feet tall, this antenna will clip a 7-foot garage door if you forget it’s up — I’ve done it twice. The 18-foot coax is permanently molded into the base, so if you pinch it in a door or it wears out, you’re replacing the whole assembly, not just a cable. A few buyers reported the set screw stripping after repeated tuning; use a quality hex key and don’t overtighten.

Also, this isn’t a stealth antenna. The stainless whip is shiny and visible from a block away. If you want something discreet, look elsewhere.

Who should buy this

This is for the CB operator who runs daily — truckers, off-roaders, or ham operators wanting one antenna for both 11-meter and 10-meter. It’s also solid for newbies who want a mount-and-forget setup with decent performance. Skip it if you’re a weekend user with a low garage, or if you need a quick-disconnect for parking decks.

FAQ

Does it fit a standard 3/8" mount? No. The SR-A10MM has a proprietary base — you can’t swap it onto existing mounts. It’s self-contained.

Do I need to tune it out of the box? Check SWR first. It’s close on most vehicles but you’ll likely need a few turns of the set screw to hit 1.5:1 or better.

Will it work on a fiberglass truck cap? No. It needs a steel surface for the magnets — place it on the cab roof or hood.

The Verdict

Buy it if: You want a rugged, high-performance magnetic antenna that handles CB and 10-meter without compromise, and you don’t mind the height.

Skip it if: You need a compact or quick-disconnect setup, or you’re on a tight budget where a $40 fiberglass whip is acceptable.

Rating: 4.2/5 — The Stryker SR-A10MM punches above its price point for performance and build quality. The height and permanent coax are real annoyances, but for daily operators, this is one of the best magnetic CB antennas under $100.
