INTRODUCING THE CD40 MULTIBAND ANTENNA SERIES 

One Antenna. No Compromises. In critical communications, vehicle roof space is a premium commodity. The CD40 series is RFI’s most innovative multiband antenna solution yet. Designed to eliminate the "antenna farm" on your roof, it delivers high-gain performance across VHF, UHF, and 700/800/900 MHz in a single, ruggedized profile.

Whether you are upgrading a fleet to multiband antenna capabilities or managing a public safety network, the CD40 provides a solution that stays connected where others fail.

Key Features:

• Ingenious Design: our engineers were able to design a unique UHF antenna that allowed for unparalleled UHF frequency coverage. The true ingenuity came in the design’s ability to minimise interference between the VHF and UHF bands, allowing the CD40 to retain pattern performance generally reserved for single-band antennas. 
  
  
• VHF (136-174 MHz) Optimized: Uses a traditional whip design to deliver best-in-class pattern performance for reliable communication. 
  
  
• Advanced UHF (378-520 MHz & 696-960 MHz) Design:
  Features a sleeved monopole design for industry-leading VSWR performance and minimized signal nulls at the horizon.
  
  
• Engineered for Next-Gen Radios: Specifically designed for modern multiband radio requirements, ensuring a perfect match and optimal performance.

CD40 Multiband VHF/UHF Antenna

Engineering the Horizon: The Concentric Advantage

Traditional multiband antennas often struggle with pattern distortion, losing signal strength where it matters most. The CD40 overcomes this through an innovative concentric radiator design.

By physically phasing and shaping the radiation patterns within the antenna structure, we’ve achieved:

• Maximum Gain at the Horizon: Keeping your signal strong at the furthest reaches of the network
• Exceptional VSWR Response: Ensuring high-efficiency power transfer across the entire spectrum
• Solid Pattern Integrity: Remains stable whether you are on a low-band LMR link or using 700MHz

SELECTING THE RIGHT CD40 FOR YOUR FLEET

The CD40 Series is available in two frequency configurations to suit your network requirements.

Each is available as a standalone replacement whip or a complete installation kit.

Built for the Modern Australian Fleet

The CD40 doesn't just sit on the vehicle; it integrates with your mission. It is specifically optimized to maximize the performance of high-tier multiband radios. 

Ruggedised by Design 

With a focus on physical durability and a reduction in moving parts, the CD40 is built to withstand the vibration and environmental extremes of Australian field use.

 A robust antenna that provides space-saving over installing multiple conventional antennas to cover the full band.
