RFI CD29-148174-50 – 148–174MHz Broadband Ground Independent Mopole
with MBC Base (Tapered Stainless Steel Radiator)
The RFI CD29-148174-50 is a high-performance VHF broadband ground independent Mopole antenna. It covers 148–174MHz and is designed for commercial, emergency services, and government communication applications.
Overview
The CD29-148174-50 is a broadband VHF Mopole antenna supplied with an MBC base. Its no-tune design eliminates the need to tune in the field, reducing installation costs and complexity while improving coverage across the whole band.
The tapered stainless steel radiator is highly flexible and resistant to knocks and bends, and the ground independent design means it doesn't rely on a large metal ground plane, useful for alternative mounting positions.
Need a different VHF sub-band? This antenna is also part of a wider CD29 series, see "Other Bands in This Series" below.
Key Features
- Broadband coverage across 148–174MHz means one antenna covers the whole band with no field tuning, for installers working through multiple vehicles on a schedule.
- 3dB gain Mopole design means stronger signal than a standard unity-gain whip, without needing a ground plane.
- Tapered stainless steel radiator means strength and durability, for vehicles working in rough conditions.
- Heavy-duty construction with flexible spring base means better durability in demanding environments.
- Optimised for rugged field conditions means dependable performance for fleets that don't get an easy ride.
Applications
- Commercial and government fleet vehicles
- Emergency service vehicles
- Utility and transport communications
- Alternative mounting positions where a full ground plane isn't available
