SPE-12-8-072/A/SS | page 2 of 9 The AP.25J active GPS patch antenna is the highest gain GPS high performance antenna currently available in the world. A 25mm GPS 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. 1.
