The dual band (L1/L5) GPS active antenna KA-7005 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 phase synchronization. The antenna is designed
with an in-built LNA to be able to be installed long distance from the BTS and with high
selectivity 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 longer and cost effective 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.
