The Dual Band (L1/L5) GPS active antenna KA-7002 filters and amplifies RF signals received from global navigation satellite systems (GNSS) and feed them to a GNSS receiver in the BTS. The GNSS receiver recovers timing and positioning data which is used to provide timing reference for TDD synchronization. The antenna  is designed to work in (very) close proximation to BTSs, protecting the GNSS receiver from possible co-location interference.

The dual band(L1/L5) antenna and receiver improves the system security. A dual band system gives remarkably better jamming and spoofing protection compared to a single band system. The good axial ratio improves the position accuracy in urban canyons where a lot of reflected and distorted GNSS signals are present. 

The high gain, low noise figure and high out-of-band rejection provided by the antenna allows for using higher loss cables, making it very easy and flexible to install. 

The dual band (L1/L5) active antenna is a fully ruggedized weather-sealed outdoor unit compliant to IP67 standards and it is compatible with several existing mounting brackets. The antenna is DC fed though the RF cable and has built in lightning strike protection.
