Vehicle-Mounted GNSS Antennas
Vehicle-mounted GNSS antennas for fleet navigation and vehicle integration. Compare mounting, receiver interfaces and satellite communication requirements.
Application Overview
Why Vehicle Antennas Are Their Own Category
Vehicles are a hostile GNSS environment: the car body blocks low-elevation satellites, the engine bay emits broadband RFI, other onboard radios (cellular, V2X, radar) create in-band interference, and installation must be quick, repeatable, and survivable to the next wash cycle. Vehicle-mounted antennas balance aerodynamics, EMC hardening, mechanical attachment, and multi-constellation reception all at once — and GNSource's vehicle line is designed for each of those trade-offs.
Select a CZ-series antenna by the required signals, receiver interface and roof installation. Include your vehicle layout, cable route and receiver model when requesting a quote.
CZBLS models combine navigation reception and BeiDou short-message functions. Select the antenna together with the terminal, required service area and receive/transmit power requirements.
Key Specifications to Consider
Mounting
Magnetic is standard; screw, shoulder-clip, and roof-mount variants available.
Band Coverage
Match the exact signal coverage to the receiver.
Tx Capability
One-line CZBLS variants add L-band Tx for BDS short message.
Configuration
Specify mounting, connector and installation requirements.
Operating Voltage Range
Plan receiver and transmitter power separately for the selected configuration.

FAQ
Vehicle-Mounted FAQs
Procurement and integration questions for vehicle GNSS antennas.
How should I choose an antenna for vehicle integration?
Start with the receiver’s required GNSS signals, antenna-port supply, connector and mounting location. Share the receiver model, cable route and installation drawing to compare suitable configurations.
Magnetic mount or screw mount?
CZ-series car ceiling antennas ship with magnetic mount as standard. One-line CZBLS variants (CZBLS4001, 4002, 4006) support both magnetic and screw mounting — selectable per order. The CZBLS3005 is specifically a shoulder-clip variant for wearable or portable applications.
What should I include in a vehicle antenna inquiry?
Include the vehicle and receiver model, required GNSS signals, mounting location, cable and connector, installation environment and quantity.
Can one antenna cover navigation plus BDS short-message for fleet tracking?
Yes. TDXL-CZBLS3001, 3002, and 3003 integrate BDS navigation, L-band short-message transmit, and S-band receive with PA + LNA in a single dome antenna — reducing cabling, weight, and installation time on commercial fleets and emergency-response vehicles.
How should I plan power for navigation and short-message functions?
Plan receive and transmit power separately. CZBLS4002 lists +6 V to +36 V for the LNA and +9 V to +36 V for the PA. Agree the selected wiring, operating modes and power budget before installation.
