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) & 25
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.
