Some Dealers swear by Lightning Arrestors, others don’t even think about them. Where do you stand on the debate?

On the back of widespread lightening storms being reported across Australia, Powertec staff have noticed an increase in products that have been ‘hit’ and have had to be replaced with the customers paying full price.

Dramatic bolts of lightning have been recorded across Australia during severe storms which have battered and damaged homes, leaving many of them without power and many electrical devices unable to work.

Lightning Arrestors provide reliable protection against dangerous surges on coaxial lines. 

The arrestors protect against resistive, magnetic field and electric field interference caused by lightning strikes, switching and other natural or man made electrical effects.


Whatever your requirement, Powertec offer 2 versions Lightening Arrestors suitable for connection to CEL-FI Smart Repeaters. 

  • Lightning Arrestor – SMA Female to SMA Female – RRP $60.50
  • SMA Male- SMA Male 75cm Cable – RRP $16.50 inc GST
