The RFI CD28-37-73 VHF Mopole Antenna delivers a 3 dB gain across the entire 138 - 163 MHz band in a ground-independent, no-tune design. Supplied with a low-profile stud mount and a pre-installed 5 m low-loss coaxial cable (unterminated), this antenna installs easily on non-traditional mounting points such as gutters, mirrors, or trunk lips. A patented matching circuit sealed inside a virtually indestructible thermoplastic body and a flexible, black powder-coated stainless-steel whip.
Product Features:
- This antenna provides wideband 138 - 163 MHz coverage, which ensures seamless VHF voice and data communications across multiple channels.
- This antenna's ground-independent Mopole architecture maintains full performance when mounted on gutters, mirrors, or other unconventional positions.
- This antenna incorporates a patented end-fed matching circuit encapsulated in a high-impact thermoplastic housing, delivering long-lasting durability and consistent 50 Ω impedance.
- The flexible, tapered stainless-steel whip is coated in a tough black powder finish to resist corrosion, vibration, and low-clearance impacts.
- This antenna includes a stud mount pre-assembled to a 5 m low-loss coaxial cable (connector not fitted), which simplifies installation and allows for custom termination.
- This antenna is designed, manufactured, and patented in Australia to withstand harsh local operating conditions.
Application Areas:
- It is ideal for fleet vehicles trucks, vans, and service cars that require reliable broadband VHF coverage without relying on a full roof ground plane.
- It is suitable for public-safety, fire, and EMS units that need a rugged antenna capable of mounting on mirrors, roof gutters, or trunk lips.
- This antenna performs reliably in mining, construction, and agricultural machinery operating in high-vibration, impact-prone environments.
- It offers flexible mounting options for urban delivery and rural logistics vehicles, overcoming space or clearance constraints.
- It is well-suited for marine and recreational off-road vehicles that benefit from its corrosion-resistant, impact-tolerant whip design.
In the Box:
- 1 x RFICD28-37-73 VHF Mopole Antenna Whip (138 - 163 MHz, 3 dB gain).
- Stud mount pre-assembled to the whip.
- 5 m low-loss coaxial cable (unterminated, connector not included).
