GNSS Active Antenna RHEA3

Description

RHEA3 is a precision GNSS antenna built for modern dual-band navigation systems. Its 
low-profile double stack design combines two 2 mm ceramic patches in a tightly 
coupled configuration, creating a total height of only 6.8 mm.  
This compact form factor is ideal for space-critical applications while preserving 
superior performance. An integrated 28 dB low-noise amplifier ensures strong signal 
reception and a low noise figure across the L1 (1575 MHz) and L5 (1176 MHz) bands, 
delivering exceptional accuracy even in challenging RF environments.
