Usage

The PolyPhaser DGXZ+15NFNF-A is an inline coaxial RF surge protector designed to safeguard sensitive radio, cellular, and wireless communications equipment from lightning strikes, electromagnetic pulses (EMP), and power transients. Installed directly between your outdoor antenna coaxial feedline and indoor network hardware (such as 4G/5G routers, remote access points, or booster systems), it channels dangerous high-voltage surges away from your electronics to ground.

Featuring PolyPhaser's patented hybrid surge protection technology, this arrestor provides low let-through energy to ensure maximum equipment longevity. Its IP67 weather-sealed construction and included mounting hardware make it suitable for tower, mast, wall, or enclosure entry-panel installations across Australian telecommunications and industrial sites.
