The RFI CD28-37-53 VHF Mopole™ Antenna delivers a 3 dB gain across the full 138 – 163 MHz band in a ground-independent, no-tune design. Supplied complete with an MBC right-angle SO-239 roof-mount base and a pre-installed 5 m low-loss coaxial cable (unterminated), it installs quickly on non-traditional mounting points such as gutters, mirrors, or trunk lips. A patented matching circuit sealed in a tough thermoplastic housing and a flexible, black powder-coated stainless-steel whip ensure long-lasting performance in demanding fleet, public-safety, and industrial environments.

Product Features:

• It provides broadband coverage of 138 – 163 MHz and a 3 dB gain advantage over a standard ¼-wave whip, delivering stronger, clearer VHF communications.
• This antenna’s ground-independent Mopoleâ„¢ architecture maintains full performance when mounted on gutters, mirrors, or other non-ground-plane positions.
• It incorporates a patented end-fed matching circuit encapsulated in a high-impact thermoplastic body, delivering virtually indestructible durability.
• The flexible, tapered stainless-steel whip resists corrosion, vibration, and low-clearance impacts while maintaining signal integrity.
• This antenna includes an MBC right-angle SO-239 base pre-assembled to a 5 m low-loss coaxial cable (connector not fitted), allowing for easy custom termination in the field.
• It is Australian designed, manufactured, and patented to withstand harsh local operating conditions.

Application Areas:

• It is ideal for fleet vehicles such as trucks, vans, and service cars that require dependable VHF coverage without a full roof ground plane.
• This antenna is suitable for public-safety and emergency-response units that require a rugged solution capable of mounting on mirrors, roof gutters, or trunk lips.
• It performs reliably on mining, construction, and agricultural equipment operating in high-vibration, impact-prone environments.
• This antenna benefits urban delivery and rural logistics applications by providing flexible mounting options that overcome space or clearance constraints.
• This antenna is well-suited for marine and recreational off-road vehicles that benefit from its corrosion-resistant, impact-tolerant whip design.

In the Box:

• 1 × RFI CD28-37-53 VHF Mopoleâ„¢ Antenna Whip (138 – 163 MHz, 3 dB gain).
• MBC right-angle SO-239 roof-mount base pre-assembled to the whip.
• 5 m low-loss coaxial cable (unterminated, connector not included).
