MA.303.A.L101131.B101111 SPECIFICATION Part No. : MA303.A.LB.002 Product Name : MA303 SAUCER Magnetic Mount GPS/GLONASS and Cellular 2G/3G 2in1 Combination Antenna Features : IP65 – Water Resistant - GPS/GLONASS - High gain LNA up to 31dB - Cellular 2G/3G - 850/900/1800/1900/2100 MHz GSM/GPRS/CDMA/PCS/DCS/UMTS/HSPA Low Profile, Robust and Stylish Design Magnetic Mounted 58.15mm x 56.2mm x 16.8mm 1 meter RG174 SMA(M) RoHS Compliant
MA.303.A.L101131.B101111 1. Introduction The MA303 SAUCER antenna is a combination small form factor high performance GPS/GLONASS and 2G/3G Cellular 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) connectors 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 Taoglas sales office for more details.
