Hirschmann GPS 916 V FLEX Roof Mounted Antenna Module (602 337-001)
The Hirschmann GPS 916 V FLEX is a robust, low-profile roof/panel mounted antenna designed for active GPS navigation and vehicle telematics. Featuring an integrated active GPS amplifier within its compact base and a durable 50mm flexible whip, it provides accurate, high-gain satellite tracking for vehicle location, fleet management, and retrofitted navigation setups.
Alternative Uses for the Secondary (FME) Antenna Feed:
Although 2G and 3G cellular services are no longer operational, the secondary antenna feed (FME male connector) remains a fully functional passive radio frequency element. Because antennas are frequency-dependent rather than protocol-dependent, this multiband whip (850/900/1800/1900 MHz) can be repurposed for modern alternative applications using an inexpensive FME-to-SMA adapter:
- LoRaWAN & Sub-GHz ISM Networks (915 MHz / 868 MHz): Perfectly frequency-matched for long-range, low-power telemetry, LoRaWAN nodes, Meshtastic off-grid comms, and remote sensor monitoring.
- 4G LTE IoT & Telemetry (Cat-M1 / NB-IoT): Compatible with re-farmed low-band 4G networks, including Band 8 (900 MHz) and Band 3 (1800 MHz) for low-bandwidth cellular modems and gateways.
- SDR & Signal Scanning (800 MHz – 1900 MHz): Excellent external vehicle whip for Software Defined Radio (SDR) receivers tracking local commercial radio, utility smart meters (915 MHz AMR), or near-band ADS-B aircraft data (1090 MHz).
Key Benefits & Product Highlights:
- Active GPS Performance: Features an integrated low-noise amplifier (LNA) built directly into the antenna base to ensure strong satellite signal lock for automotive GPS units.
- Flexible Low-Profile Design: Equipped with a short, flexible 50mm rubber whip tilted at a 74° angle to prevent impact damage in low-clearance areas - note that it is highly recommended to remove the mast section for automated car washes.
- Weather-Proof & Durable: IP6K4 weather resistance rating (when properly mounted with the included seal), built to withstand harsh automotive operating environments.
- Direct Vehicle Mounting: Installs into standard square (15mm x 15mm) or round (Ø 19mm) vehicle panel mounting holes.
Important Cellular / GSM Compatibility Note:
Please note that while this legacy module includes
integrated GSM/3G cellular capability, 2G (GSM) and 3G networks have been decommissioned across Australia and many international
regions. This unit is primarily recommended as a brand-new OEM replacement for its active GPS system, specialised retrofits,
or hard-to-find legacy system repairs.
