Bias Tees
A bias tee lets you power an active GPS/GNSS antenna or inline LNA through the same coax cable that carries your RF signal; no separate power wire needed. This is essential for GPS/GNSS receivers, SDR setups, and any application using an antenna with a built-in amplifier.
Choosing the right bias tee depends on your frequency range and voltage requirements: wideband bias tees work across 10 MHz–7000 MHz for general RF/SDR use, while GNSS-filtered bias tees add integrated filtering specifically tuned to GPS L1-L5, GLONASS, BeiDou, and NavIC bands for cleaner reception in RF-noisy environments.
