GPS and BeiDou Dual Frequency Active Antenna Car DVD Navigation Antenna SMA-Male Length=1.5M

Description

Description

The GPS and BeiDou Dual Frequency Active Antenna is a high-performance, externally mounted GNSS antenna specifically designed for automotive navigation systems, in-dash DVD players, head units, and other vehicle-based positioning applications. Supporting both GPS L1 (1575.42 MHz) and BeiDou B1 (1561 MHz) frequencies, this antenna enables multi-constellation reception for faster Time-To-First-Fix (TTFF), improved positional accuracy, and more reliable navigation in urban canyons, tree cover, and other challenging environments.

This is an active antenna, meaning it features a built-in Low Noise Amplifier (LNA) that boosts weak satellite signals before transmitting them down the cable to your navigation receiver. The integrated LNA compensates for signal loss inherent in the 1.5-meter cable, ensuring that your GPS/BeiDou receiver receives a clean, strong signal even when the antenna is mounted remotely from the main unit.

The antenna is housed in a durable, low-profile, weather-resistant black casing with a magnetic base (or adhesive backing, depending on variant) for easy installation on metal surfaces. The 1.5-meter coaxial cable is terminated with a standard SMA male connector, which is compatible with the vast majority of car DVD navigation units, aftermarket head units, and GNSS receiver modules featuring an SMA female antenna port.

Key internal components include a high-gain ceramic patch antenna element and a high-quality LNA with low noise figure (≤1.5dB) and high gain (28dB typical), ensuring excellent signal reception even in weak signal conditions. The antenna draws its operating power (3V–5V DC) directly from the navigation receiver through the same coaxial cable, requiring no external power source.

Whether you are installing an aftermarket car DVD player, replacing a damaged GPS antenna, building a vehicle tracking system, or upgrading the navigation capability of a marine or RV head unit, this GPS/BeiDou dual-frequency active antenna delivers reliable, multi-constellation performance in a rugged, easy-to-install package.

Key Features

• Dual GNSS Band Support – Tuned for both GPS L1 (1575.42 MHz) and BeiDou B1 (1561 MHz) for multi-constellation navigation

• Active Amplification (LNA) – Built-in Low Noise Amplifier boosts weak satellite signals, improving sensitivity and reducing TTFF

• High Gain (28dB typical) – Provides strong signal output to overcome cable losses in 1.5-meter cable runs

• Low Noise Figure (1.5dB typical) – Minimizes signal degradation introduced by the amplifier

• SMA Male Connector – Standard connector compatible with most car DVD navigation units, head units, and GNSS receivers

• 1.5 Meter Cable Length – Sufficient length for routing through dashboards, A-pillars, and headliners to optimal mounting locations

• Magnetic Base Mount – Easy, tool-free installation on any ferrous metal surface (roof, trunk lid, dashboard metal frame)

• Weather-Resistant Housing – Durable black ABS casing suitable for outdoor and vehicle roof mounting

• Low Profile Design – Compact, discreet appearance when mounted on windshield, dashboard, or vehicle exterior

• Wide Operating Temperature – -40°C to +85°C, suitable for extreme automotive environments

• Right-Hand Circular Polarization (RHCP) – Matches GNSS satellite signal polarization for maximum signal transfer

• Plug-and-Play Installation – No external power required; antenna receives power directly from the receiver via coaxial cable
