An active GPS antenna is powered by supplying it with DC voltage through the same coaxial cable that carries the RF signal to the GPS receiver. The receiver typically provides the necessary voltage, usually between 3 to 5 volts, to the antenna via the cable. This setup allows the integrated low-noise amplifier in the active antenna to boost the GPS signals for improved reception.
