Surge Protectors: The Best Option to Protect Your Wireless Network

by Stuart Berry September 04, 2017

A single bolt of lightning carrying up to 100 million volts of electricity has the power to rip through roofs, explode brick walls and destroy electronic networking/communications equipment! but what if you never receive direct strikes? Indirect lightning strikes on telephone and power lines can be just as destructive. Protect your valuable communications equipment with L-com's HyperLink® brand coaxial surge protectors.

One of the first things you may be wondering is, "Where is the best place to put coax surge protectors in my wireless network?" The typical examples below outline some  of the recommended areas to place coax surge protectors to protect your valuable communications equipment.

  • At the base of your wireless antennas (for integral connector models)
  • At the connector end of the antenna pigtail (for pigtail antennas)
  • At the ingress of a NEMA Enclosure
  • Between any cable end connected to active equipment such as access points and RF amplifiers

*Important Note: Always remember to ground the protector to EARTH ground via 8 or 10 gauge copper wire*

L-com's HyperLink® coaxial lightning arrestor and surge protector products come in two types, Quarter Wave and Gas Discharge models.

Quarter Wave coaxial surge protectors are designed to pass the desired frequency while suppressing lightning surges, very like a signal filter. Lightning strike electrical surges which operate at low frequencies are diverted through the protector's short-circuit to the ground.


Diagram of a Gas Discharge Lightning Protector

Gas Discharge coaxial protectors are a type of lightning arrestor which utilises a replaceable gas discharge tube, which is a component containing a small amount of gas. The gas tube dumps very high amounts of surge energy directly to the ground of the protector. HyperLink® coaxial lightning arrestors are available for 0-3 GHz operation or 0-6 GHz operation.
