Browning 3-5/8 in NMO Mount Magnet Antenna - Rugged Mobile Mount

In this review the Browning 3-5/8 in NMO Mount Magnet is evaluated as a simple, durable mobile antenna mount for CB and two-way radio use. The bottom line: this mount is for anyone who needs a robust, no-fuss magnetic NMO mounting solution with a long, factory-terminated coax lead. It stands out because the solid brass construction and integrated rubber boot protect the base while the 7 ft RG-58 A/U cable with tinned copper braid and a PL-259 connector make installation straightforward and compatible with common radio setups.

Key Features

• Solid brass mount: Provides corrosion resistance and a sturdy connection point for antenna installations on metal surfaces.
• Rubber boot protection: The boot helps seal the mount base from moisture and reduces wear where the mount contacts the vehicle roof.
• 7 ft RG-58 A/U cable: A factory-attached 7 ft coax lead gives flexibility in routing to the radio without immediate need for additional cabling.
• Tinned copper braid 95%: High braid coverage improves shielding and reduces signal loss in typical CB and two-way radio frequencies.
• UHF Male PL-259 connector: The installed PL-259 with strain relief allows quick, reliable connection to many radios and mobile adapters.

Who It's For

The Browning NMO mount is aimed at mobile radio users who want a ready-to-install magnetic mount that pairs with standard PL-259 terminated equipment. It suits truckers, hobbyists, and field technicians who value simple setup, corrosion-resistant materials, and a pre-terminated 7 ft coax lead for quick installation behind dashboards.

Those who need a permanent, through-hole mount or specialized low-loss coax for very long runs should look elsewhere, since this product is a magnetic NMO mount with a fixed-length RG-58 cable intended for convenience and moderate runs rather than permanent rooftop installs or high-performance long feeder runs.

Pros & Cons

Pros

• Strong, corrosion-resistant solid brass construction for durability in outdoor and mobile use.
• Included rubber boot reduces water ingress and protects the contact surface during use.
• Factory-installed 7 ft RG-58 cable with tinned braid and PL-259 simplifies hookup to radios.

Cons

• RG-58 coax is adequate for short to moderate runs but is not the lowest-loss option for long-distance or high-power setups.

Our Verdict

The Browning 3-5/8 in NMO Mount Magnet is a practical, value-focused choice for anyone needing a quick, durable magnetic NMO mounting solution with a ready-made coax and PL-259 termination. Its solid brass build and rubber boot deliver long-term reliability for mobile CB and two-way radio use, while the 7 ft RG-58 lead makes installation fast; choose a different mount only if you require a permanent through-hole install or lower-loss coax for long runs.

Frequently Asked Questions

Will this mount work with common CB antennas?
Yes. The NMO-style mount and PL-259 terminated cable are compatible with most CB and two-way antenna setups that accept an NMO base and UHF connections.

Is the cable pre-terminated or will I need to attach a connector?
The unit ships with a factory-installed 7 ft RG-58 A/U cable and a UHF Male PL-259 connector with strain relief already fitted.

Is this suitable for permanent rooftop installation?
No. This is a magnetic mount designed for temporary or removable mobile use; choose a through-hole mount for a permanent rooftop installation.
