More Information

DC to 6 GHz Operation

The SP6-230-BFF surge protectors from Laird Technologies are an integral part of any antenna installation involving the protection of sensitive equipment from surges caused by lightning. The ultra fast discharge design gives quick response to power surges and dumps the excess power safely to ground.

Grounding is accomplished via a ground lug terminal or N bulkhead connector. The units have the ability to withstand multiple lightning strikes. The SP6 passes DC voltage so it is also suitable for those systems which pass DC power through the coax such as remote amplifiers. Construction is all plated brass to resist corrosion.


  • Ultra fast gas discharge < 1KV / usec
  • 0.2 dB @ 2.4 GHz,
  • .4 dB @ 5 GHz max insertion loss
