Full -Protection:The Surge Protector is a -arrester of coaxial construction. The device is designed to the surge of -strikes on an antenna at the top of a and ground it, thus providing full -protection for transceivers, receivers, etc.When the thunder wave comes, you can back and High Performance and Multifunctional:The coaxial construction of this device assures high frequency characteristics, wide bandwidth and low loss and VSWR.1/4 wavelength short circuit principle for good -protection effect. Simple structure, strong, easy installation High Safety:Designed with a stress on high safety, this device has a built-in -charging surge arrestor which discharges and grounds the surge at the moment the surge voltage exceeds a specified level.These arresters are vailable with several coaxial connection schemes and with multiple RF power ratings Repeated Surge Discharge and :This device makes the actions of surge discharge and restoration as repeatedly as necessary. No replacement is practically needed .Should the surge arrestor be damaged, it can be replaced with a new Specifications: Model: CA-35RS Connector: UHF/UHF Frequency range: 0-3000MHz Voltage standing wave : 1.1 power: 400w Voltage: DC 230A Current: 500A Impedance: 50 ohms Size: 78 x 41 x 20mm / 3.1 x 1.6 x 0.8in Colour: as shown Material: Metal Size: 4.33 x 3.15 x 1.18 inches Package Contents: 1 x -Arrester Only the above package content, other products are not included.
