Product Description
antenna feeder transient voltage surge suppressor surge protector for radio transmission
Introduction
DK-f Antenna Feeder series signal surge protective device (SPD) is designed according to IEC standard. It is suitable for lightning protection of satellite antenna and microwave signal transmission, etc. With features of integration metal structural design, high discharge capacity and fast response, it can effectively ensure the equipment to work properly.

Working Principle
DK-f n Antenna Feeder SPD adopts band-pass filtering theory to design and manufacture elaborately. High quality filter network and with standing 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
1) Antenna feeder of mobile base station.
2) Satellite receiving antenna.
3) Short wave (SW) or ultra-short wave antenna feeder.
4) CATV amplifier.
5) Microwave antenna feeder.
6) Radio transmission and receiving equipment.
Ordering Instruction
a. Before placing an order, please must be clear the working frequency of electronic equipment, connector of antenna feeder and equipment..
b. Any special requirements(e.g. connector, working frequency), please contact with us, so that we can produce the customized product according to your requirements.
c. Any problems, please feel free to contact us. We will serve you wholeheartedly.
