Product Description

Hot sale surge arrestor n type rf lightning surge protector for radio transmission

Introduction

DK-f n Antenna Feeder SPD adopts metal shell material. With the advantages of good sealing, anti-radiation, good shielding, easy installation, dust prevention and anti-corrosion, it is suitable for cable TV, SATV, repeater station and other equipment of antenna feeder system. It can protect the equipment of antenna feeder system from permanent damage or instantaneous interruption because of induced over-voltage, over-current and other instantaneous surge voltage produced by lightning stroke or industrial noise.

DK-f n Antenna Feeder SPD has the characteristics of wide working frequency, low insertion loss, low residual voltage, fast respond and long life, etc.

Model	Working Frequency (GHz)	Insertion loss(Db)	VSWR	In (8/20μs)	Imax (8/20μs)	Up (8/20μs)	Port type
DK-f n Type	0-2.5GHz	≤0.3	≤1.2	10kA	20kA	≤150V	F-J/K

Working Principle

DK-f n Antenna Feeder SPD adopts band-pass filtering theory to design and manufacture elaborately. High quality filter network and withstanding surge current discharge channel form the Antenna Feeder SPD with fine performance.

Installation Instruction and Precaution

a. DK-f n Antenna Feeder SPD is connected between antenna transmission system and protected equipment in series. b. According to the connector type of antenna feeder and protected equipment, please select the right connector, connect to the protected equipment, and make sure the connector is connected firmly.

c. The mark in bottom of the product is grounding screw. There is wiring port which is used for connecting the grounding wire and antenna feeder SPD. The grounding wire is better to use 4mm2 copper wire, or to use grounding bar. Ground wire should be thick and short as possible to reduce the ground resistance(better less than 10Ω). During using, please also check grounding system to avoid the grounding wire opening circuit or being over-length.

Maintenance

No need special maintenance. When failure, replace the internal gas discharge tube is OK.

Application Scope

Suitable for surge protection of cable TV, SATV, repeater station and other equipment of antenna feeder system.
