Phaseblocker RP-SMA Male to Female Surge Arrester - DC to 6 GHz


Key Features


  • Reverse Polarity SMA Male to Reverse Polarity SMA Female connectors

  • Designed for Wi-Fi/wireless equipment

  • For devices operating 0-40 W

  • Bi-directional protection

  • DC Pass

  • Removable L bracket for bulkhead panel mounting

  • Protect your radio hardware from dangerous electrical surges.




  • Gas tube lightning protection with excellent VSWR and superior RF performance characteristics for equipment operating DC to 6 GHz with up to 40 W RF power

  • Male to Female arresters are designed for installation in-line between an antenna and feeder cable

  • By installing at the tower-top position, this arrester helps protect the end user equipment and the cabling itself.

  • When feeder lengths exceed 20-30 m vertically, we recommend a second arrester at the equipment end of the cable, to protect against parasitic coupling

  • The arrester features a bulkhead RP-SMA Female connector to mount through an enclosure wall, or to tower mount with the included stainless steel bracket

  • Given the critical nature of remote communications, this high grade surge suppressor is  designed with safety as a priority

  • This device has a built-in multi-strike gas-charging surge arrester element, which discharges and grounds the surge the moment the surge voltage exceeds the pre-specified level

  • This device makes the actions of surge discharge and restoration repeatedly, with tube replacement rarely required.
