Technical Data

DC Stop is used in dual- or multi-band antenna systemswhere one or more antenna systems require a DC supplyfor an installed mast head amplifier. The DC Stop preventsDC voltage from being shorted within the non-biasedantenna system(s) and isolates the corresponding basestation output(s) from DC voltage.

• Low RF signal insertion loss• High DC signal isolation from port 1 to port 2 and vice versa• Suitable for indoor or outdoor applications
