    The UC-1574-431R 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 (+10 dBm IIP3, In -5 dBm/Out +18 dBm P1dB), +22 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-1574-431R 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.

    This antenna has been reported to work exceptionally well as a GPS Microcell Antenna, or GPS Femtocell Antenna for local (free) 3G connectivity. The UC-1574-431R has been successfully used on Microcells operating in RF noisy environments and concrete building basements. AT&T Microcell models require an MCX Male connector (-MCXM), Verizon Microcell models use an SMB Female connector (-SMBF).

    LNA power is provided by your GPS receiver through the coaxial cable. No external power supplies are necessary. The UC-1574-431R 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.
