31182 27 dBi GPS Antenna with 3 V Magnetic Mount and SMA Connector

Overview

The 31182 is a magnetic mount GPS patch antenna. It is typically used where GPS reception is readily available and concern is low for snow buildup completely covering the antenna. The 31182 is also commonly used in cost-sensitive applications or applications that require a small-sized, low-profile antenna. This antenna connects to a GPS receiver with SMA connector, such as that found in the AL200, LS300G, and TX320. The antenna package is waterproof and corrosion resistant. The 31182 conveniently mounts to any magnetic surface, which includes the 30626 and CM235 mounts offered by Campbell Scientific.
