Product Description

The RFI CD28-37-50 VHF Mopole™ Antenna is a ground-independent, broadband solution covering 138 – 163 MHz with a 3 dB gain advantage over standard ¼-wave whips. Supplied with an MBC right-angle SO-239 roof-mount base (cable not included), the antenna features a patented matching circuit housed in a virtually indestructible thermoplastic body and a flexible, tapered stainless-steel whip that shrugs off knocks and bends. Its versatile, no-ground-plane design allows reliable performance when mounted on gutters, mirrors, trunks, or other non-traditional locations.

Product Features:

  • The broadband coverage of 138 – 163 MHz delivers seamless VHF voice and data communications across multiple channels.
  • It is ground-independent Mopoleâ„¢ architecture enables dependable performance on unconventional mounting points such as mirrors or roof gutters.
  • Patented, end-fed matching circuit is sealed in a high-impact thermoplastic housing for long-lasting durability.
  • This antenna is flexible, tapered stainless-steel whip resists corrosion, vibration, and low-clearance impacts while maintaining signal integrity.
  • It provides a 3 dB gain improvement over a conventional ¼-wave whip, extending coverage range and signal clarity.
  • It includes an MBC right-angle SO-239 base for fast, secure installation (coaxial cable supplied separately).
  • This antenna is Australian designed, manufactured, and patented engineered for harsh local conditions.

Application Areas:

  • Fleet vehicles - trucks, vans, and service cars requiring broadband VHF communications without a full roof ground plane.
  • Public-safety and emergency-response units needing rugged antennas that can be mounted on mirrors or gutter brackets.
  • Mining, construction, and agricultural machinery operating in vibration-prone, abrasive environments.
  • Urban and rural installations where obstructions or limited roof space demand versatile mounting options.
  • Marine and recreational off-road vehicles that benefit from a flexible, impact-resistant whip and corrosion-resistant materials.
