Product Description

The RFI CD28-41-73 VHF Mopole™ Antenna is a ground-independent, broadband solution that delivers a genuine 3 dB gain across the full 148 – 175 MHz band. Supplied with a low-profile threaded stud mount and a factory-installed 5 m low-loss coaxial cable (unterminated), it can be fitted quickly on mirrors, gutters, trunk lips, or any other tight mounting location. A patented end-fed matching circuit sealed in a virtually indestructible thermoplastic housing, together with a flexible, black powder-coated stainless-steel whip, ensures dependable performance for fleet, public-safety, and industrial vehicles in the harshest environments.

Product Features:

  • The Mopoleâ„¢ architecture is ground-plane independent and offers a 3 dB improvement in signal levels over a conventional quarter-wave whip.
  • Broadband coverage of 148 – 175 MHz with 4 MHz bandwidth at 1.5 : 1 VSWR (8 MHz at 2.0 : 1), field-tuneable with the supplied chart for optimal match.
  • A patented end-fed matching circuit is encapsulated in a high-impact thermoplastic body, delivering a stable 50 Ω impedance and outstanding durability.
  • The tapered 17-7 PH stainless-steel whip is finished with a tough black powder-coat, giving excellent resistance to corrosion, vibration, and low-clearance impacts.
  • A threaded stud mount is pre-assembled to a 5 m low-loss coaxial cable (connector not included), allowing fast, custom termination during installation.
  • Designed, manufactured, and patented in Australia (AU #596830 & #656793) for reliable service in extreme operating conditions.

Application Areas:

  • It is ideal for fleet trucks, service vans, and logistics vehicles that need broadband VHF coverage but lack a large roof ground plane.
  • It is suitable for public-safety, fire, and EMS units requiring a rugged antenna that can mount securely on mirrors, roof gutters, or trunk lips.
  • It performs reliably on mining, construction, and agricultural machinery operating in environments with heavy vibration, dust, and physical impacts.
  • It benefits urban delivery and rural logistics vehicles where overhead obstacles limit antenna height and ground-plane availability.
  • It is perfect for marine and recreational off-road vehicles that require a corrosion-resistant, impact-tolerant whip and ground-independent performance.

In the Box:

  • 1 × RFI CD28-41-73 VHF Mopoleâ„¢ Antenna Whip (148 – 175 MHz, 3 dB gain, factory-tuned centre).
  • Threaded stud mount pre-assembled to the whip.
  • 5 m low-loss coaxial cable (unterminated, connector not included).
