78210850V01 DC Isolator (DC Stop)

Appointments

DC Stop is used in dual or multi-band antenna systems where one or more antenna systems require DC power for the installed masthead amplifier. DC Stop prevents DC voltage short circuits in the omnidirectional antenna system(s) and isolates the corresponding base station output from DC voltage.
