Antenna
Source high-quality automotive antennas in bulk from vetted manufacturers and suppliers. Designed for importers, wholesalers, distributors, and aftermarket brands, this catalog offers reliable OEM and ODM production for radio, GPS, and multi-band antennas. Secure competitive pricing and consistent quality for your supply chain.
Sourcing automotive antennas at volume requires balancing aesthetic design with strict radio frequency (RF) performance standards. Whether you are stocking universal replacement masts or developing custom multi-band shark fin antennas for modern vehicle roofs, signal integrity, environmental durability, and vehicle contour matching are non-negotiable. Success depends on partnering with factories that possess both advanced injection molding capabilities and proper RF testing environments.
Critical Specifications for Automotive Antennas
When communicating your requirements to an antenna manufacturer, vague specifications lead to poor reception and high return rates. Modern automotive antennas often combine AM/FM, GPS, and cellular (4G/LTE/5G) into a single housing. You must specify the precise performance metrics required for each band.
| Specification | Standard AM/FM Mast | Active Multi-Band (Shark Fin) |
|---|---|---|
| Frequency Range | AM: 520-1710 kHz / FM: 87.5-108 MHz | Adds 1575.42 MHz (GPS), 700-2700 MHz (LTE) |
| VSWR (Voltage Standing Wave Ratio) | Under 2.0 | Under 1.5 (critical for GPS/LTE) |
| Impedance | 75 ohms (typical for radio) | 50 ohms (standard for active data/GPS) |
| Amplifier Gain | Passive (0 dB) | Active: 15 dB to 28 dB (requires 12V power) |

Talk to our teamManufacturing Tolerances and Quality Control
The primary failure points for exterior automotive accessories are water ingress and UV degradation. A factory's ability to produce a reliable antenna relies heavily on their tooling precision and assembly processes. Relying on visual checks is insufficient; rigorous Quality Control & Inspection must be implemented during production.
Key QC Checkpoints for Automotive Antennas
- Waterproofing: Verify IP67 or IP68 ratings, focusing on the EPDM rubber base gasket and cable entry points.
- UV Resistance: Ensure the housing is molded from UV-stabilized ABS or Polycarbonate to prevent fading and brittleness.
- PCB Assembly: Inspect solder joints on the internal amplifier board, particularly where the copper element connects to the PCB.
- Cable Quality: Confirm the use of low-loss coaxial cables (like RG174) with secure, crimped Fakra or DIN connectors.
- RF Chamber Testing: Require sample testing in an anechoic chamber to verify VSWR and gain meet your specified parameters.
Customization and OEM/ODM Production
If you are developing a proprietary design or a multi-band antenna tailored to a specific vehicle model's roof curvature, you will need robust OEM/ODM Services.
Developing a new shark fin or low-profile antenna involves two distinct engineering tracks: mechanical (the housing and gasket) and electrical (the PCB and antenna element). The housing must be aerodynamically stable and perfectly contoured, while the internal volume must be sufficient to house the active components without causing interference. Before investing in tooling, conducting thorough Factory Audits ensures the manufacturer has in-house engineering support and does not outsource critical PCB design to unverified third parties.
Pricing, MOQs, and Lead Times
Automotive antenna pricing is driven by the complexity of the internal electronics (passive vs. active) and the quality of the raw materials (copper elements vs. cheaper alloys).
Prices for basic universal replacement masts typically range from $0.50 to $2.00 per unit. Active, multi-band shark fin antennas with integrated GPS and amplifiers generally range from $3.00 to $8.00 per unit, depending on the gain specifications and connector types (e.g., dual Fakra cables).
