The RFI CD28-37-70 VHF Mopole™ Antenna is a ground-independent, broadband solution covering 138 – 163 MHz with a 3 dB gain boost over a conventional ¼-wave whip. Supplied with a low-profile stud mount (cable not included), the antenna uses a patented end-fed matching circuit sealed in a tough thermoplastic housing, while its flexible, tapered stainless-steel whip shrugs off knocks and bends. Ideal for fleet, public-safety, and industrial vehicles, it performs reliably even when installed on mirrors, gutters, or other non-traditional locations where a ground plane is absent.
Product Features:
- Wideband 138 – 163 MHz coverage provides seamless VHF voice and data communications across multiple channels.
- The ground-independent Mopoleâ„¢ design maintains full performance when mounted on gutters, mirrors, trunks, or other unconventional mounting points.
- The patented matching circuit is encapsulated in a high-impact thermoplastic body, which delivers virtually indestructible durability and consistent 50 Ω impedance.
- The flexible, black powder-coated stainless-steel whip resists corrosion, vibration, and low-clearance impacts while preserving signal integrity.
- The included stud-mount hardware enables quick, secure installation, and the coaxial cable and connector can be selected to suit your radio system.

Application Areas:
- It is ideal for fleet vehicles trucks, vans, and service cars that require dependable broadband VHF coverage without a full roof ground plane.
- This antenna is suitable for public-safety, fire, and EMS units that require a rugged solution capable of mounting on mirrors, roof gutters, or trunk lips.
- It performs reliably on mining, construction, and agricultural machinery operating in high-vibration, impact-prone environments.
- This antenna benefits urban delivery and rural logistics operations 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.
