1. Introduction
The AP.25J active GPS/GALILEO patch antenna is the highest gain GPS/GALILEO high
performance antenna currently available in the world. A 25mm GPS/GALILEO patch
antenna with three stage LNA delivers 40dB of gain. This product is suited for applications
such as timing applications for base stations or out-building installations which need long
cable lengths to the receiver, typically over lengths exceeding 5M at RG174 and over 30M
using low loss cable as CFD200 or LMR200.
