Our review of the Tram 1121+1247MUHF trunk mount VHF antenna kit finds it best suited for installers and mobile radio users who need a compact, pre tuned antenna solution for Motorola mobile radios. The bottom line: this kit pairs a 17in chrome quarter wave VHF antenna with a trunk mount and MUHF connector, delivering straightforward installation and reliable on-vehicle performance across 150-162 MHz without the need for additional tuning. For anyone running compatible Motorola mobiles, the kit removes guesswork and minimizes on-roof clutter while keeping coax length options flexible.

Key Features

• Pre tuned 14 wave NMO quarter wave: Provides a ready-to-fit VHF element that is tuned for 150-162 MHz so users avoid manual tuning at installation.
• 17in chrome antenna: Offers a low-profile, rust-resistant finish that balances reception performance with a tidy visual profile on the vehicle roof.
• 1247 trunk mount included: Supplies a trunk mount option for clean installation without drilling through the roof, useful for many vehicles.
• 17 ft of RG-58 coax: Gives ample cable length for routing to the radio mounting location in most cars or trucks without needing extra cable.
• MUHF connector: Ensures direct compatibility with Motorola mobile radios that accept MUHF terminations, simplifying hookup.

Who It's For

This kit is aimed at fleet technicians, amateur installers and end users who operate Motorola mobile radios such as CM300, CDM and Maxtrac style units and want a plug-and-play VHF antenna solution. The included MUHF connector and pre tuned element make it a good fit for on-vehicle work where avoidance of additional tuning and easy connectivity are priorities.

Those who need a heavy-duty magnetic mount, a multi-band or UHF antenna, or a custom length coax should look elsewhere, because this kit is focused on mobile VHF service with a trunk mount and RG-58 cable as supplied.

Pros & Cons

Pros

• Compact 17in element delivers respectable VHF coverage while remaining unobtrusive on the vehicle roof.

• Includes 17 ft of RG-58 coax and a trunk mount, so the kit is ready for most typical mobile installations.
