This product description details a complete, ready-to-deploy GPS antenna assembly optimized for reliable satellite navigation and positioning. The combination of a high-gain active element, a flexible RG174 cable, and the ubiquitous SMA Male connector makes it an ideal choice for mobile and fixed asset tracking, telematics, and timing applications.
Optimized GPS Signal Performance
The antenna is specifically engineered for the fundamental GPS L1 signal, ensuring maximum efficiency and signal integrity.
Tuned Frequency: Precisely centered at 1575.42 MHz, the frequency of the GPS L1 band. This singular focus ensures minimal noise and maximum reception of the crucial navigation signal.
High Gain and Active LNA: This is an active antenna, meaning it includes a built-in Low Noise Amplifier (LNA). The LNA is critical for boosting the faint satellite signals immediately upon reception, often providing a typical gain of 26 dB to 30 dB (LNA gain, not antenna gain). This high amplification compensates for cable losses and significantly improves the receiver's overall sensitivity, leading to faster Time-To-First-Fix (TTFF) and better performance in challenging signal environments (e.g., inside vehicles or near buildings).
Right-Hand Circular Polarization (RHCP): The antenna is designed for RHCP reception, matching the polarization of the satellite-transmitted signals. This polarization matching is crucial for minimizing the effects of multipath interference (signals bouncing off surfaces) and ensuring stable signal lock.
Antenna Element Gain: The inherent gain of the patch or ceramic element is typically around 4-5 dBi, contributing to overall signal strength before LNA amplification.
Flexible and Reliable Cable Assembly
The integrated cable provides the necessary connectivity while maintaining installation flexibility in confined spaces.
RG174 Coaxial Cable: The assembly utilizes RG174 coaxial cable. This cable is known for its:
High Flexibility: The small diameter (approx. 2.8mm / 0.11 inches) and stranded conductor make the cable highly flexible and easy to route through tight enclosures and around corners, which is essential for mobile installations.
Low Profile: The thin cable minimizes bulk and weight, making it aesthetically pleasing and easy to conceal.
Length: Cable lengths are typically customizable, commonly ranging from 1 meter to 5 meters.
SMA Male Connector: The cable terminates with a standard SMA Male connector. The SMA connector is selected for its:
Secure Connection: The threaded coupling mechanism provides a secure, vibration-resistant, and reliable mechanical and electrical connection, ideal for automotive and mobile environments.
Wide Compatibility: It ensures direct, plug-and-play compatibility with a vast majority of commercial and industrial GPS receivers, modems, and tracking devices.
Rugged Construction and Versatile Mounting
Designed for permanent outdoor or vehicular use, the antenna's physical structure ensures maximum durability.
Weatherproof Housing: The LNA and antenna element are protected by a rugged, sealed, UV-stabilized casing, often rated to IP65 or IP67 standards. This ensures resistance to dust, moisture, and extreme temperatures.
Mounting Options: The design typically includes integrated mounting options for diverse installations:
Magnetic Base: Ideal for quick, temporary, or semi-permanent mounting on ferrous metal surfaces (e.g., vehicle rooftops).
Screw/Bolt Mount: Provides a permanent, secure, and tamper-resistant attachment to industrial enclosures or fixed assets.
