With a low axial ratio and excellent out-of-band rejection, this antenna delivers superior signal quality and robust performance even in areas with high RF interference. Typical applications include: - UAVs and Robotics - Autonomous Vehicles - High Accuracy Positioning - Public Safety Systems - Precision Agriculture - • Navigation The AA.205 includes LNAs and front-end SAW filters to reduce out of band noise, such as from nearby cellular transceivers. It offers better protection from nearby radiated power surges and greatly reduces the probability of damaging your GNSS receiver from nearby transmissions. The AA.205 has 1 cable feed as the L1, L2 and L5 feeds are combined with a hybrid coupler and the antenna performance results are shown in the below sections. The cable and connector are fully customizable, subject to NRE and MOQ.
