Shark Fin Car Antenna

Shenzhen Qianmu Communication Technology Co., LTD., legitimate China Shark Fin car antenna Manufacturer, Source Factory, global reliable Supplier, mainly automotive-grade multi-in-one vehicle antenna. All products are equipped with multi-band RF PCB arrays, and the measured signal stability far exceeds that of traditional pole antennas. Integrated AM/FM radio, GPS/Beidou positioning, 4G/5G cellular, 2.4G/5.8G WiFi multi-channel, supporting OEM for vehicle manufacturers and bulk supply for aftermarket modification.

Product Definition

The Shark Fin car antenna is a low-profile streamlined integrated vehicle-mounted radio frequency antenna that discards the split structure of the old-fashioned single-function rod-shaped antenna and integrates multi-band receiving elements, signal amplification modules, and shielding structures within a single waterproof housing, taking into account both aerodynamic appearance and multi-signal synchronous reception capability. It is currently the mainstream antenna category for passenger cars, logistics fleets, and special engineering vehicles. The housing is made of low-loss ABS/PC automotive-grade plastic and does not shield electromagnetic waves; The interior is lined with microstrip PCB antenna arrays corresponding to radio, satellite positioning, cellular network, and wireless local area network.

Product Core Features

1. Integrated Multi-Function Design

The shark fin car antenna adopts an all-in-one integrated design, allowing a single antenna to support multiple functions, including AM/FM radio, GPS, 4G/5G communication, and WiFi connectivity. This eliminates the need for multiple roof openings, reducing vehicle assembly costs and minimizing potential water leakage risks.

2. Automotive-Grade Weather Resistance

Designed with an IP67 waterproof and dustproof housing, the antenna provides excellent resistance against UV aging and harsh environmental conditions. It ensures stable operation from -40°C to +85°C, maintaining reliable performance without cracking or water penetration in heavy rain, snow, and coastal salt spray environments.

3. Streamlined Low-Drag Design

The aerodynamic shark fin structure effectively reduces wind resistance and minimizes driving noise. Compared with traditional vertical rod antennas, it can reduce high-speed wind noise by up to 60%. The streamlined design blends naturally with the vehicle body without increasing fuel consumption.

4. Enhanced Signal Reception Performance

The built-in signal amplification system improves reception stability in weak signal areas, including mountainous regions, elevated roads, and underground parking garages. Field tests show stable signal reception without noticeable noise, while maintaining uninterrupted GPS satellite positioning.

5. Factory Direct Customization Service

As a professional automotive antenna manufacturer and factory, we provide full customization options, including housing color, cable length, SMA/BNC/Fakra connector types, and frequency band combinations. Customer logos can also be printed to support OEM and branding requirements.

Technical Specifications

5. RV and Camping Vehicle Audio-Visual Systems

Providing stable radio reception and satellite navigation in remote outdoor camping areas, replacing the complicated layout of separate multi-antennas.

Easy Installation Guide1. Opening and Positioning:

Reserve installation holes on the vehicle roof and clean dust and oil around the installation area.

2. Cable Routing and Fixing:

Pass the built-in cable of the Shark Fin Car Antenna through the roof hole into the vehicle, align the antenna base, and press the waterproof gasket firmly into place.

3. Base Locking:

Tighten the matching nuts from inside the vehicle to secure the antenna base, ensuring the rubber ring is fully attached to the roof to prevent water leakage.

4. Wiring Harness Connection:

Connect the radio, GPS, 4G/WiFi cables to the corresponding interfaces of the infotainment system and T-BOX device.

5. Sealing Completion:

Wrap waterproof tape around the nuts, secure the wiring harness inside the vehicle, and complete the installation.

How to choose a suitable Shark Fin car antenna

Many purchasers tend to choose the wrong frequency band or specification. Here are three ways to quickly select the model:

1. By vehicle type for family cars: 3-in-1 (FM+GPS+4G) standard Shark Fin car antenna; Logistics fleet/special vehicles: 5-in-1/6-in-1 full-band model with high-power amplification module; Rv/Bus: Extended 8-meter cable Shark Fin car antenna;

2. For coastal areas with heavy rain and high salt fog: Choose an upgraded version with a thickened anti-corrosion shell; Northern regions with sub-zero temperatures: Custom versions of low-temperature weather-resistant cables;

3. According to the interface of the equipment to be connected, overseas vehicle manufacturer Fakra interface, foreign trade wholesale SMA male connector, domestic equipment BNC, inform the engineer to match the interface before placing the order.

FAQ

Q1: Does it leak when it rains?

A1: No. The base is equipped with a one-piece molded waterproof gasket. The whole machine is IP67 sealed and has undergone continuous spray waterproof tests before leaving the factory. It won't seep water even in rainy days and car washes all year round.

Q2: Can the color and LOGO of the shell be customized?

A2: Supported. As a source Factory, customizable black, white, and grey enclosures, silk-screened customer brand LOGO, and adjustable frequency bands and cable lengths.

Q3: Does the Shark Fin car antenna have to be installed with a hole in the roof? Are there any hole-free options?

A3: The standard model is a roof thread fixed (with the best sealing effect); A strong magnetic base antenna can be custom-made to fit the modification requirements if no drilling is needed.

Q4: Is the antenna signal gain falsely labeled? Can test reports be provided?

A4: All parameters are measured in the radio frequency anechoic chamber and there is no false labeling. The corresponding batch antenna test report can be provided simultaneously after placing the order, and the data can be verified.
