Description

This Lightning Arrestor is an inline gas discharge tube (GDT) surge protector for the antenna ports of Cisco Catalyst IR1800 Rugged Series routers. It is aimed at outdoor and remote deployments with externally mounted cellular or GNSS antennas, such as oil and gas sites, solar and wind farms and EV charging, where lightning-induced surges on the antenna cable are a risk to the router.

It is a straight SMA male to SMA female unit covering DC to 6 GHz, which spans cellular, Wi-Fi and GNSS bands. Because it passes DC, it can be used with active GNSS antennas that are powered through the cable. The gas tube design is a passive protection element, so no power, licence or subscription is needed.

Cisco lists this arrestor as an option for the SMA antenna ports of the IR1800 series. Other arrestors in the same Cisco lists use N-type or TNC connectors, or are high-pass filter types that do not pass DC and do not support GNSS, so this SMA GDT version is the one to choose when DC pass is required.

Enquire with XS Network Tech for new or used pricing and availability.
