DC Injector
DC injectors (bias tees) put DC power onto a coaxial feeder so tower-top amplifiers, masthead electronics and active antennas can be powered without separate cabling — while keeping DC out of the equipment that must not see it.
Check voltage, current rating and frequency range against your device, and note that DC-blocked surge protectors will not pass injector power — choose DC-pass protection on powered runs.
