The RFI CD28-41-50 VHF Mopole Antenna delivers a 3 dB gain across the entire 148 - 174 MHz band in a ground-independent, no-tune design. Supplied with an MBC right-angle SO-239 roof-mount base (cable not included), the antenna pairs a patented matching circuit sealed in a virtually indestructible thermoplastic body with a flexible, black powder-coated stainless-steel whip that shrugs off knocks and bends.

Product Features:

• Broadband coverage of 148 - 174 MHz provides seamless VHF voice and data communications across multiple channels.
• The ground-independent Mopole architecture maintains full performance when mounted on gutters, mirrors, trunks, or other unconventional locations.
• A patented end-fed matching circuit encapsulated in a high-impact thermoplastic housing delivers consistent 50 Ω impedance and long-lasting durability.
• The flexible, tapered stainless-steel whip with a tough black powder coating resists corrosion, vibration, and low-clearance impacts.
• This antenna provides a 3 dB gain improvement over a conventional ¼-wave whip, extending coverage range and improving signal clarity.
• An MBC right-angle SO-239 base is included for quick, secure roof-mount installation (coaxial cable supplied separately).
• Designed, manufactured, and patented in Australia for dependable performance in harsh local conditions.

Application Areas:

• Fleet trucks, service vans, and logistics vehicles require broadband VHF communications without a full roof ground plane.
• Public-safety, fire, and EMS units need rugged antennas that can mount on mirrors, roof gutters, or trunk lips.
• Mining, construction, and agricultural machinery operate in high-vibration, impact-prone environments and benefit from this antenna's robust design.
• Urban delivery and rural logistics vehicles benefit from flexible mounting options that overcome space or clearance constraints.
• Marine and recreational off-road vehicles require corrosion-resistant, impact-tolerant whips for reliable communications.

In the Box:

• 1 x RFICD28-41-50 VHF Mopole Antenna Whip (148 - 174 MHz, 3 dB gain).
• MBC right-angle SO-239 roof-mount base pre-assembled to the whip.
