These devices are used for the protection of Radio Equipment attached to antennas.  Designed by RF engineers as military-grade as well as the commercial broadcast industry, perfect for your Ham Radio station too.

They will protect from sand, rain, and snow static buildup on antennas and feed lines which can damage sensitive radio equipment. They will also protect against damage from nearby and overhead lightning strikes and can mitigate damage to radios and other equipment from occurring inside buildings, enclosures, and homes.

Based on the design by Industrial Communications Engineers (ICE) 309H  coaxial arrestors, these arrestors have been improved in performance, packaging, and  hardware. These arrestors are DC blocked and include static and DC discharge capabilities just like the famous ICE arrestors. They also include rated Gas Discharge Tubes (GDT) which can be replaced (NOTE: Recommended GDT voltage rating: 2700 V) with simple tools. Due to the static bleed components inside the arrestors not only does it help to keep the tube from firing extending the life of the GDT, but by virtue of bleeding off static that is charging the coaxial cable it eliminates cable discharge noise from the sensitive receiver which can lower the noise level heard.

It is designed for use with open single wire, or open twin-line transmission lines. They can handle Zo line impedances from 300 to 600+ ohms. They are meant to be mounted near the lightning grounding system, at ground level.

Installation Note:

When using a Remote Tuner at or near the Antenna please consider installing it between the antenna and the ATU as the DC control voltage for the tuner will not pass through this device.
