The CR8894SXF+ from Calian is a 4-Element GNSS Controlled Reception Pattern Antenna (CRPA) that operates from 1189 to 1254 MHz (lower) and 1559 to 1591 MHz (upper). It is designed to null interference or jamming signals across multiple GNSS constellations – GPS, Galileo, GLONAS, and BeiDou. This antenna uses CRPA and eXtended Filtering (XF+) technologies to provide reliable communication by creating radiation pattern nulls in the direction of the jammer, and isolating lower and upper bands. It also integrates Tallysman Accutenna technology that enhances null-forming performance.
The CR8894SXF+ CRPA antenna also integrates an LNA that provides 28/35 dB of gain, along with a filter that provides up to 20-40 dB of out-of-band rejection. This integrated antenna can be controlled remotely using RS232 and RS422 interfaces. The LNA consumes 150 mA of current. This antenna is available in an IP67-rated rugged surface-mount package and has TNC (Female) & SMA connectors. It is ideal for critical timing, navigation in contested areas, law enforcement, and critical infrastructure applications.
