Polyphaser's SX series of surge arrestors use a patentedspiral inductor design. The almost instantaneous response to alightning surge minimizes energy let-through and protects criticalwireless equipment. Models available with ultra-low PIM and DC Pass(AISG) capability,used in 4G and 5G applications.

• Frequency Ranges from DC to 11GHz
• 4.3-10, 7/16" DIN, N-Type, TNC, and SMA
• Available with low PIM
• Repeatable RF performance after surge
• Weatherproof when installed

The IS-B50 Series of DC block surge arrestors are designed toprotect against lightning events and are ideal for HF, UHF and VHFradios. The IS-B50 family of RF protectors can be used for generalradio use with frequency ranges between 1.5 MHz to 1000 MHz.

• Broad frequency ranges from 1.5 MHz to 1000 MHz
• Connectors: N-Type and UHF
• High power versions capable to 3kW
• Industry leading surge rating of 20kA
• Nuclear EMP versions available with N-Type connectors
• Flexible bulkhead and bracket mounting options
