SPE-24-8-298-A 

The compact Magma AA.185 is an adhesive/magnetic mount antenna is ideal for covert installations where durability and small size is paramount. This low-profile antenna is tuned for stable operation over GPS, GLONASS, Galileo and BeiDou L1/E1/B1 frequency bands and is used in a wide range of applications where GNSS services are required. At only 35mm square and 15mm in height, it is one of the most compact high accuracy antenna in the market for L1 operation. The robust ASA IP67 rated enclosure allows the Magma X to be used either internally or externally in challenging environments. 

Typical Applications include: 

- Advanced Telematics, Navigation and Fleet Management 

- M2M applications, Construction and Agriculture 

- High accuracy timing and positioning systems 

The use of a dual-pin patch design improves the axial ratio at the centre of the band, delivering right hand circular polarization. The helps increase location accuracy and improve the speed of time to first fix for GNSS systems used in challenging environments. A front-end SAW reduces out-of-band interference from any nearby wireless transmitters, helping prevent LNA compression and burnout. 

3m of RG-174 cable is used as standard with and an SMA(M) connector, both are customizable upon request. An alternate version with a dual stage LNA design is also available, see the AA.186. For further information, contact your regional Taoglas customer support team.
