GPSD4503P

Antennas RF Overview

The GPSD4503P is a passive Global Positioning System (GPS) antenna manufactured by TE Connectivity. It operates within the L1 frequency band, specifically centered at 1575.42 MHz with a bandwidth of 1559 to 1596 MHz. The component provides a gain of 2.8 dBi and maintains a Voltage Standing Wave Ratio (VSWR) of 2.0 maximum. It features an N-type female connector for interfacing and utilizes a panel mount installation method. The physical dimensions include a height of 1.5 inches (38.1 mm) and a diameter of 1.5 inches (38.1 mm).

Antennas RF Feature Summary

• Passive design optimized for Global Positioning System (GPS) signal reception.
• Compact cylindrical form factor suitable for space-constrained installations.
• Integrated ground plane functionality inherent to the structural design.

Antennas RF Applications

• Vehicle tracking and fleet management systems.
• Maritime navigation equipment.
• Aviation avionics and navigation units.

Antennas RF Procurement Notes

Verify that the specific order matches the GPSD4503P designation to ensure correct L1 band operation. Confirm that the receiving equipment interface supports an N-type female connector. Ensure the installation environment allows for the required panel mounting clearance and does not obstruct the antenna's vertical radiation pattern.

Antennas RF Selection Notes

Select this model when a dedicated passive GPS solution is required rather than a combined GNSS unit. The N-type connector offers robust mechanical coupling compared to smaller RF interfaces. Consider the 2.8 dBi gain as sufficient for standard line-of-sight applications where high-gain active antennas are unnecessary.

Antennas RF Part Context

This component belongs to the TE Connectivity Laird Passive Antennas portfolio. It is designed specifically for reliable GPS signal acquisition in mobile platforms. The product complements other navigation antennas by providing a specialized single-band solution for the primary GPS L1 frequency.
