TDD20K20#-T

 MAIN FEATURE:

  • Large discharge current;
  • Low residual voltage
  • Low insertion loss and voltage standing wave rate (VSWR),
  • quick respondence ;
  • Stabile capability;
  • Installation simple and maintenance free.
TDD20K20#-T (1/4 wavelength) series antenna lightning protectors designed for antenna coaxial device and receive/transmit system avoid destruction result from lightning over-voltage, induced over-voltage and static discharge.

 INSTALLATION

 

1.   Connect the protectors in series to the antenna circuit, and the protector should be closed to the equipment as much as possible.

2.   Make connection lead as short as possible (lead section area not more then 2.5mm²), and another port connect protector with grounding bar reliably.

3.   Using outdoors must avoid rainwater immerging into the protector to erode the inner components.

4.   No special maintenance needed. When malfunction occurs in operating system, remove protector, and check the system. If system recovers, it means the protector has been damaged and must be replaced.
