Check the listing for details. PolyPhaser 099-0105T-B Coaxial RF Surge Protector - Lightning Arrestor -Heliax. Condition: Used. Listed at 30.00 USD. I don't know much about these and I couldn't find much online. They were installed in a local ham radio shack, in line with Heliax cable to a UHF antenna. Searching the Delta 9226-000-A911 part number on the coax connector, this is showing as a 7/16 50 ohm connector.
