1. Comprehensive Protection: Absorbs and grounds surges from antennas on top of buildings, providing complete protection for transceivers, receivers, etc.2. Safety Guarantee: Designed with high safety in mind, the built in inflatable arrester elements discharges and grounds the surge when the surge voltage exceeds a specified level.3. Convenient and Practical: Surge discharge and recovery action can be repeated as needed. If the arrester components are damaged, they can be easily replaced with new components.4. Superior Performance: The coaxial structure of the surge protector ensures excellent high frequency characteristics, wide bandwidth, low loss and VSWR.5. Easy Installation: The coaxial surge arrester adopts 1/4 wavelength short circuit principle, good protection. Simple structure, sturdy and easy to install.Item Type: Coaxial ArrestorModel: -3000Connector: N male to N FemaleFrequency Range: DC~1000MHzVoltage VSWR: less than equal 1.1 : 400WImpedance: 50 OhColour:As shownMaterial:Stainless steelPackage Contents:1 x -3000 N male to N female ArrestorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
