The RFI CD28-41-53 VHF Mopole™ Antenna supplies a 3 dB gain across the full 148 – 175 MHz band in a ground-independent, no-tune design. Shipped with an MBC right-angle SO-239 roof-mount base and a factory-fitted 5 m low-loss coaxial cable (unterminated), the antenna installs easily on non-traditional mounting points such as gutters, mirrors, and trunk lips.
Product Features:
- The ground-independent Mopole™ architecture delivers a 3 dB improvement over a conventional ¼-wave whip, extending communication range.
- The broadband 148 – 175 MHz coverage supports multiple VHF channels without retuning.
- A patented end-fed matching circuit, sealed inside a high-impact thermoplastic housing, provides consistent 50 Ω impedance and exceptional durability.
- The tapered 17-7 PH stainless-steel whip features a tough black powder coating that resists corrosion, vibration, and low-clearance impacts.
- An MBC right-angle SO-239 base, pre-assembled to a 5 m low-loss coaxial cable, allows custom field termination to suit your radio system.
- This antenna uses a unique termination method that simplifies installation and re-cabling, reducing downtime during maintenance.
- This antenna is Australian designed, manufactured, and patented to ensure dependable operation in harsh climates.
Application Areas:
- This antenna is ideal for fleet trucks, service vans, and logistics vehicles that lack a full roof ground plane but require strong VHF coverage.
- It is suitable for public-safety, fire, and EMS units that need rugged antennas for mounting on mirrors, roof gutters, or trunk lips.
- It performs reliably on mining, construction, and agricultural machinery operating in high-vibration, impact-prone environments.
- It benefits urban delivery and rural logistics vehicles where flexible mounting options overcome space or clearance constraints.
- It is well-suited for marine and recreational off-road vehicles that benefit from corrosion-resistant, impact-tolerant whips.
In the Box:
