Fixed GNSS installation
Screw mounting with an active GPS/GLONASS signal path
GL-DY225 combines GPS at 1575.42 ± 3 MHz with GLONASS at 1602–1610 MHz in a screw mount housing. The original source explicitly names GL-DY225 inside the PDF, despite its archive filename ending in D.
The antenna is RHCP and includes an LNA with 40 dB typical gain. The source specifies a 2.7–10 V DC supply, less than 25 mA current and a TNC connector; the receiving equipment must provide the appropriate active-antenna bias.
Its mechanical section lists screw mounting, an ABS radome and IP67 ingress protection. Confirm the TNC mating interface, installation seal and supply budget for the intended assembly.
