## Overview

YASP1G-NFF protects sensitive radio equipment from lightning-induced surges across HF, VHF and UHF applications. Its DC-blocked circuit isolates the protected equipment side while maintaining low insertion loss and excellent impedance matching from 20 MHz through 1 GHz.

The solid-brass protector supports repeat surge events and mounts through a bulkhead or by its universal grounding bracket. Outdoor installations require appropriate connector and enclosure weatherization. Contact Satel USA for help confirming power handling, grounding and installation requirements for your radio system.
