GPS Passive L1 Antenna, +1.5 dBic Gain, Integrated Sealed RF Coaxial Gooseneck Assembly
Product Overview
Southwest Antennas Part # 1027-014 is a high-performance, ruggedized GPS Passive L1 Antenna designed for GPS receivers, manpack, hand-held, and small form factor radio systems. This antenna features an integrated RF coaxial gooseneck assembly that allows for flexible antenna positioning, ensuring the antenna can be pointed skyward for optimal GPS reception when the radio is body-worn or otherwise mounted in a non-vertical position. The gooseneck is sealed with Polyolefin heat shrink providing a waterproof seal to 20 meters / 65.6 ft.
Key product features include a quadrifilar helical antenna design, excellent axial ratio, compact size, and light weight. These features make the antenna capable of receiving a clear GPS signal even in very congested and noisy RF environments
