AT190 Helix Antenna
AT190 Helix Antenna
Description
The compact-sized AT190 helix antenna is designed with high
stability and repeatability at phase center, and its high gain ensures
a superior performance even at low elevation angle. Available from
single frequency to triple frequency, AT-series Helix antennas are
optimal for Unmanned Aerial Vehicle, GIS, RTK and related mobile
devices where need high accuracy GNSS positioning.
Features
