UC-1574-429R, GPS L1 antenna, RHCP, +8 dB LNA

The UC-1574-429R is a Quadrifilar Helix Antenna (4 cm/1.5" OD x 11 cm/4.5" H) designed for use with GPS L1, 1.5754 GHz receivers and systems.

It features a built-in, robust (+21 dBm IIP3, In +6 dBm/ Out +15 dBm P1dB), +8 dB Low Noise Amplifier, preceded by a GPS filter, and followed by another GPS filter (2 filters). This combination of a small QFHA, a tough LNA and 2 filters, makes the UC-1574-429R an ideal antenna for very harsh electromagnetic environments, or in applications where GPS performance is affected by out-of-band interference from other devices, such as a radio transmitter.

LNA power is provided by your GPS receiver through the coaxial cable. No external power supplies are necessary. The UC-1574-429R is very tolerant of wide voltage variations and voltage range. Minimum supply voltage for nominal operation is +3.5 VDC. Operation at lower voltages gracefully derates performance of the LNA.
