Overview
The Desite B4BE Series is a rugged, broadband omnidirectional antenna engineered for reliable RF performance in industrial M2M and IoT connectivity applications. Designed around a coaxial dipole-based radiating structure with optimized ground-plane coupling, the antenna operates across a continuous frequency range of 600–6000 MHz—fully covering all major 2G (GSM 900/1800), 3G (UMTS 2100), 4G (LTE Bands 1–40, including Band 7, 20, 28, 38, 41), and sub-6 GHz 5G NR (n1, n3, n7, n28, n41, n78) cellular bands. Its radiation pattern exhibits near-isotropic azimuthal distribution (±2.5 dB variation) and a vertical beamwidth of approximately 70°, enabling consistent link budget performance regardless of device orientation or mounting asymmetry. The antenna’s impedance is matched to 50 Ω over its entire operational bandwidth, minimizing VSWR (<2.0:1 typical) and ensuring efficient power transfer from standard LTE modems and cellular gateways.
Key Features
- Wideband operation from 600 MHz to 6000 MHz—single-antenna support for legacy and next-generation cellular standards
- Moderate gain profile: 3.5–5.2 dBi across operating bands, optimized for balanced coverage and penetration in mixed indoor/outdoor deployments
- IP66-rated enclosure constructed from UV-stabilized polycarbonate and stainless-steel hardware, certified for continuous outdoor exposure under rain, dust, and temperature cycling (-40 °C to +85 °C)
- Low-profile mechanical design (height ≤ 280 mm, base diameter ≤ 85 mm) minimizes wind loading and visual impact while maintaining structural rigidity
- Mounting flexibility: includes universal U-bolt mast clamp (Ø30–60 mm) and wall-mount bracket with adjustable tilt (±15°), compatible with DIN-rail adapters for industrial enclosures
- Integrated 50 Ω N-type female connector with PTFE dielectric and gold-plated contacts, rated for ≥500 mating cycles
Sample Compatibility & Compliance
The B4BE Series is validated for interoperability with major LTE Cat-1, Cat-4, Cat-6, and 5G NR sub-6 GHz modules—including Quectel EC25/EC21, Telit LE910, Sierra Wireless HL78xx, and u-blox LARA-R6/LISA-U2 families. It complies with IEC 60529 (IP66), EN 60950-1 (safety), EN 55032 Class B (EMC emissions), and EN 55035 (immunity). While not a measurement-grade antenna per IEEE 149 or ANSI C63.5, it meets functional requirements for field-deployed telemetry systems under ITU-R SM.328 and ETSI EN 301 908-1/-2 compliance testing environments. Its passive design ensures zero electromagnetic interference generation—critical for co-location with sensitive RF test equipment in antenna characterization labs.
Software & Data Management
As a passive RF component, the B4BE requires no embedded firmware or driver software. However, its performance integration is fully supported within standard RF system validation workflows: antenna gain and VSWR data are provided in S1P Touchstone format for import into Keysight PathWave ADS, CST Studio Suite, or MATLAB Antenna Toolbox. Field deployment diagnostics—including RSSI, RSRP, SINR, and handover latency—are monitored via modem AT-command interfaces or vendor-specific SDKs (e.g., Quectel QNavigator, Telit DeviceWise). For traceability in regulated utility or smart metering deployments, installation logs (mounting location, azimuth/elevation, cable loss compensation) can be recorded in CMMS platforms compliant with ISO 55001 asset management frameworks.
Applications
- Smart utility infrastructure: AMI (Advanced Metering Infrastructure) endpoints for electricity, water, and gas metering networks requiring long-range, low-duty-cycle LTE-M/NB-IoT uplinks
- Remote industrial monitoring: SCADA telemetry from pump stations, substations, and environmental sensor arrays where mast-mounted antennas improve path margin over foliage or building obstructions
- Transportation telematics: Fleet tracking units, onboard diagnostics (OBD-II) gateways, and rail-side IoT nodes deployed in high-vibration, wide-temperature environments
- Public safety communications: Backup LTE links for emergency response radios and portable command centers operating in fringe coverage zones
- Research-grade RF propagation studies: Reference antenna for comparative path-loss modeling in urban canyon or semi-rural test corridors
FAQ
Is the B4BE Series suitable for anechoic chamber calibration or SAR measurements?
No—it is a commercial-grade connectivity antenna, not a calibrated reference standard. For EMC or SAR testing, use NIST-traceable, fully characterized antennas such as Schwarzbeck UBBVxx or ETS-Lindgren 3142 series.
Can this antenna be used with 5G mmWave (24–39 GHz) devices?
No. The B4BE operates exclusively below 6 GHz. mmWave 5G requires separate phased-array or lens-coupled antennas with waveguide interfaces.
What is the maximum recommended cable length between the antenna and modem?
For optimal SNR at 3500 MHz, use ≤10 m of LMR-400 or equivalent low-loss coaxial cable; longer runs require active amplification or site survey-based link budget analysis.
Does the antenna support MIMO configurations?
The B4BE is a single-input single-output (SISO) antenna. For 2×2 or 4×4 MIMO, deploy multiple B4BE units with ≥λ/2 spatial separation and orthogonal polarization alignment.
Is RoHS and REACH documentation available for export compliance?
Yes—material declarations and substance compliance certificates are provided upon request for EU, UKCA, and APAC market registrations.
