AD-80/L1L2 — Mobile GPS Active Receiving Antenna

Overview

The AD-80/L1L2 is an active receiving GPS antenna designed for mobile and portable receivers. Covering both L1 and L2 bands, it features an integrated Low Noise Amplifier (LNA) within a durable ABS radome, ensuring reliable signal acquisition for mobile platforms.

Technical Summary

• Operating Frequencies: GPS L1 (1575 MHz) and L2 (1227 MHz)
• Polarization: Right Hand Circular (RHCP)
• Amplification: Integrated 30 dB LNA
• Power Handling: Receive-only
• Mounting: M10 threaded stainless steel adapter
• Cable/Connector: 5-meter RG-316 with SMA male

Operational Use Cases

Engineered for positioning applications, providing enhanced satellite signal reception for mobile and portable GPS receivers in the field.

Deployment Environments

Designed for ground vehicles and portable handheld setups, utilizing a rugged ABS enclosure and stainless steel hardware to endure mobile field conditions.

Performance Metrics

• Frequency Support: 1227 MHz and 1575 MHz (L-Band)
• LNA Gain: 30 dB
• Total Gain Rating: 16 to 32 dB

Setup & Portability

Features a stainless steel mounting adapter with an M10 thread, washers, and nut for straightforward installation. The unit includes a pre-attached 5-meter RG-316 coaxial cable, avoiding the need for field termination.

Compatibility

Compatible with standard mobile and portable GPS receivers utilizing an SMA male connector. It can function as a standalone antenna or mount directly onto standard VHF/UHF broadband mobile antenna bases (such as Trival AD-18/D, AD-27, or AD-18/E) by substituting an existing M10 mounting screw.

FAQs

• Can this antenna be used for transmitting signals? No, it is designated as an active receive-only antenna. Transmitting power through receive-only antennas can cause permanent damage to system components.
• What does the RHCP specification signify? Right Hand Circular Polarization (RHCP) describes the orientation of the antenna's electric field. This matches the polarization broadcast by GPS satellites to minimize polarization mismatch loss during reception.
• How does the antenna connect to the GPS receiver? The unit features an integrated 5-meter RG-316 coaxial cable terminated with an SMA male connector. Verify this connector matches your receiver's input port prior to installation.
• Problems we solve: where do we start with incomplete requirements? An incomplete specification can make product selection difficult. Start by sharing the task, operating environment and known constraints with Cyntony so the team can help define what to verify and which options are worth discussing (Our process).
• Outcomes we deliver: what comes from working through the requirements? The practical outcome is a requirements-led set of product options to evaluate with Cyntony. Confirm performance, compatibility and any service scope for your configuration before selection (Our process).
