LRTA

Long Range Tracking Antenna System

For customers that require extremely long line-of-sight (LOS) connectivity, we are offering the Long Range Tracking Antenna (LRTA). The LRTA consists of two parabolic dish antennas, tracking gimbal, Silvus 4400 Streamcaster radio, cables, tripod mount and hard cases. The LRTA tracks the position of the Vector air vehicle in space and locks the antenna mainbeam onto the vehicle. Utilizing the appropriate set of airborne antennas, the LRTA can provide radio link range out to 160km (100 miles). We are currently offering the LRTA in S-Band dual S and C-Band operation coming soon.
