Tallysman Wireless Incorporated RF Antennas 33-3870-01-11

The Quarktwin Technology Ltd. RF Antenna, part number 33-3870-01-11, is designed for precision dual frequency positioning, supporting GPS L1/L2, GLONASS G1/G2, BeiDou B1, and Galileo E1 signals. It features a circular dual-feed, stacked patch architecture that enhances signal reception and minimizes multipath interference. The antenna provides a minimum gain of 3.8 dBic at L2 and 4.5 dBic at L1 when used with a recommended 100mm ground plane. With a low noise figure of 1.5 dB and a typical LNA gain of 35 dB, the antenna operates efficiently across a supply voltage range of +2.5 to 16VDC. It is housed in a weather-proof enclosure rated IP67, making it suitable for permanent outdoor installations. The antenna also includes ESD protection up to 15 kV and is compliant with RoHS and REACH standards. Its operating temperature range is from -40°C to +85°C, ensuring reliability in various environmental conditions. This antenna is ideal for applications requiring high accuracy, such as dual frequency RTK receivers, military and security operations, and network timing and synchronization.
