PolyPhaser B50 DC Block RF Protection

For most HF, UHF, VHF radios operating in the frequency range of 1.5 - 1000MHz, including Base Mobile Radio, the B50 series is best suited for low cost applications. The IS-B50 is a dc blocked 50 Ohm bulkhead mounted protector and should be connected directly to a single point ground.
