It supports GPS (L1, L2, L5), GLONASS (G1, G2, G3), COMPASS/BeiDou (B1, B2, B3), and Galileo (E1, E2, E5a, E5b, E6), covering the major signals for high-precision, multi-constellation operation.
This low phase center error is critical for surveying and RTK applications, as it minimizes position errors caused by antenna geometry, ensuring higher measurement accuracy. The exact value is guaranteed per datasheet.
The LNA operates on a wide voltage range of 3 to 16V DC, with a current consumption of ≤60mA. This flexibility allows compatibility with various survey receivers and power systems.
It uses a screw mounting method for a secure, fixed installation. The RF output is provided via a standard TNC female connector.
The antenna is rated IP67, offering protection against dust and temporary immersion. The note "excluding air vent in screw hole" indicates the IP rating is maintained when the vent in the mounting screw hole is not obstructed.
Yes, with its robust ASA radome, IP67 protection, wide operating temperature range, and low phase center stability, it is well-suited for permanent, unattended base station setups.
The antenna provides a full 360° horizontal coverage angle, ensuring signal reception from all directions.
