Description
Description
The Kerlink KLK02900 (CITEL PRC822S-NMF) is an RF lightning & surge arrestor — a critical infrastructure component for any outdoor LoRaWAN installation. Using "Quarter Wave" technology, this coaxial protector provides a robust path to ground for the high-energy surges caused by lightning strikes, isolating and protecting the sensitive RF circuitry of your gateway.
Optimised for the 800–2200 MHz range, it delivers maximum safety without compromising signal integrity or coverage. With an N-Male to N-Female inline design and an IP65 weatherproof body, it's built to sit on the antenna feed of tower- and rooftop-mounted gateways.

Frequently Asked Questions
What does the KLK02900 protect against?
High-energy surges from direct or nearby lightning strikes. Using "Quarter Wave" technology, it routes the surge safely to ground and isolates your gateway's sensitive RF circuitry.
Where is it installed?
Inline on the coaxial run between the antenna and the gateway, bonded to the mast or earth bar for an effective ground.
Will it weaken my signal?
Minimally — it offers Return Loss >20 dB, VSWR <1.2:1, and insertion loss <0.2 dB across 800–2200 MHz, preserving signal integrity and coverage.
What connectors does it use?
N-Male to N-Female, so it fits directly into standard N-type coaxial antenna feeds.
Is it suitable for outdoor use?
Yes — it has an IP65-rated weatherproof body built for permanent tower and rooftop installation.
Does it require maintenance?
No. The bi-directional "Quarter Wave" design has no consumable parts to replace — it's a fit-and-forget, maintenance-free protector.
