PREFACE

This text specifies the basic operational characteristics of the active GPS antenna modules MA-19/MA-25/MA-66/MA-67 under a standard test condition of 3 V DC (MA-19) / 5 V DC (MA-25/66/67) & 25oC/ 50% R.H.

INTRODUCTION

MA-19 / MA-25 / MA-66 / MA-67 is the integration of a high performance GPS patch antenna and a state-of-the-art low noise amplifier into a very low profile/ extremely compact/ fully waterproof enclosure which, when connected to a GPS receiver with 3 V DC or 5 V DC antenna power, provides excellent signal amplification and out-band filtering & rejection.

INSTALLATION

1. Secure your MA-19 / MA-25 / MA-66 / MA-67 antenna to the top of your vehicle and carry its cable into the vehicle.
2. Link the cable connector to your GPS receiver.
3. Start with your navigation.
