I. 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 3V DC (MA-19)/ 5V DC (MA-25/66/67) & 25oC/

50% R.H.

II. 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 3V DC or 5V

DC antenna power, provides excellent signal amplification and

out-band filtering & rejection.

IV. 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.
