Tram Browning Magnet Mount NMO Antenna Kit UHF 450-465 MHz

Our review of the Tram Browning Magnet Mount NMO Antenna Kit finds it best for mobile radio users who need a compact, pre-tuned UHF solution for Motorola and similar mobile radios. The single biggest reason to consider this antenna is its factory pre-tuning to the 450-465 MHz band combined with a low profile NMO mount and 17 ft of coax, which makes installation straightforward and performance predictable for in-vehicle use. Reviewers who value a ready-to-install kit that covers common UHF mobile frequencies will appreciate the balance of build quality and usable output power.

Key Features

• Pre-tuned 450-465 MHz: Ensures the antenna is optimized for common UHF channels so users spend less time trimming or tuning on site.
• Up to 100W power handling: Allows compatibility with higher-power mobile transceivers without immediate thermal or power limits for typical mobile use.
• 3 1/4' magnet NMO mount: Provides a secure, low-profile magnetic base that sits flat on vehicle roofs and is easy to remove when needed.
• 17 ft RG-58 coax: Extra cable length simplifies routing to mobile radios installed under dashboards or in trunks without needing an extension.
• mini-UHF connector: Matches many Motorola mobile radios and makes a direct, low-loss connection when the radio supports that connector type.

Who It's For

This kit is tailored to amateur radio operators, fleet installers, and mobile radio users who operate around 450-465 MHz and want a neat, low-profile magnet mount solution that is ready to fit to many Motorola mobiles. The included 17 ft RG-58 cable means installers can place the radio unit out of sight while keeping signal loss modest for typical mobile distances.

Users who need a specialized antenna outside 450-465 MHz, a permanently roof-mounted hardmount, or a coax type other than RG-58 should look elsewhere. Also confirm your radio's connector compatibility before buying because not all mobile radios share the mini-UHF interface.

Pros & Cons

Pros

• Pre-tuned factory frequency band saves time and ensures consistent performance on UHF channels.
• Robust construction with a copper coated brass NMO base and gold contact pin for reliable electrical contact.
• Generous 17 ft cable and a magnet NMO mount make installation flexible and non-permanent.
• Handles up to 100W, suitable for many mobile transceivers without immediate power concerns.

Cons

• Magnet mount is not a permanent roof installation and may not suit long-term exposed use in severe weather or high-speed environments.
• mini-UHF connector requires checking radio compatibility as not all mobiles use this connector type.

Frequently Asked Questions

Will this antenna work with my Motorola mobile radio?
It will work if your radio accepts a mini-UHF connector; check the radio manual for connector compatibility before purchasing.

Can the magnet mount stay on the vehicle permanently?
The magnet NMO mount is convenient for non-permanent installation but is not a sealed permanent roof mount; prolonged exposure or high-speed use may require a hardmount.

Does the kit include the coax and connector?
Yes, the kit includes 17 ft of RG-58 coax with a mini-UHF connector attached for direct connection to compatible mobile radios.
