Active L-Band Patch Antenna

The Taoglas ALPDF254 is an active L-Band patch antenna for use on the L-Band spectrum required for positioning correction services. The antenna exhibits excellent gain and good radiation pattern stability leading to a reliable performance, enabling a high precision GNSS receiver to reach accuracies down to centimeter level. The satellite L-band communication system allows GNSS correction service providers to broadcast a variety of services on specific channels, satellites and beams, and the ALPDF254 has been expertly designed to be used in conjunction with L-Band receivers.

Typical applications include:
– UAVs and Robotics
– Autonomous Vehicles
– Precision Agriculture

The ALPDF254 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 receiver from nearby transmissions. The ALPDF254 has 1 cable feed as the two pin feeds are combined with a hybrid coupler to get the best possible axial ratio for L-Band applications.

The cable and connector are fully customizable, subject to NRE and MOQ. For further information please contact your regional Taoglas customer support team.
