Description:The Surge Protector is a lightning arrester of coaxial construction. The device is designed to absorb the surge of lightning strikes on an antenna at the top of a building and ground it, thus providing full lightning protection for transceivers, receivers, etc.Features:Designed with a stress on high safety, this device has a built-in gas-charging surge arrestor element which discharges and grounds the surge at the moment the surge voltage exceeds a specified level.This device makes the actions of surge discharge and restoration as repeatedly as necessary. No replacement is practically needed .Should the surge arrestor element be damaged, it can easily be replaced with a new element.The coaxial construction of this device assures excellent high frequency characteristics, wide bandwidth and low loss and VSWR.1/4 wavelength short circuit principle for good lightning protection effect. Simple structure, strong, easy installation.Specifications:Material: IronColor: BlackModel: CA-35RSConnector: UHF/UHFFrequency range: 0-2500MHzVoltage standing wave ratio: 1.1Peak power: 400wVoltage: DC 230ACurrent: 500AImpedance: 50 ohmsSize: 78 x 41 x 20mm / 3.1 x 1.6 x 0.8inPackage weight: 105gPackage List:1 x Coaxial Lightning Surge ProtectorNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
