sp e - 14 - 8 - 079 / a /wy ma.303.a.l101131.b101111 1. introduction the ma 30 3 saucer antenna is a combination small form factor high performance gps /glonass and 2g/3g cellul ar gsm /gprs/cdma/ pcs/dcs/ wcdma/umts antenna to simplify remote monitoring and fleet management worldwide. it comes with magnet ic mount as standard. an internal o - ring meets ip - 65 waterproof standards. with th e strongest gps /glonass and cellular antenna design team in the industry and rigorous testing taoglas offers guaranteed performance with your system and your environment. a front end saw helps prevent lna compression and burn out from nearby high power wir eless transmissions. it also reduces radiated spurious emission failures in certification. an integrated strain resist helps prevent cable damage from accidental tension on the cable. the standard ma303 version comes with 1 metres rg174 cable and sma(m) c onnectors for both gps /glonass and cellular feeds. cables and connectors are customizable upon request. due to typical rf losses, 1 metre cabl e length is optimal, it is not recommended to use longer than 3 metre cables. contact your regional taogla s sales office for more details. features gps /glonass ? high lna gain up to 3 1 db ? antenn a gain 28 2 db ? miniaturized to 56. 2 x 1 6 . 8 mm ? low noise figure 2.8 db typ. for gps 3.2 db typ. for glonass ? ultra - low power consumption 7~10 ma typ .
