• AS-309H - Twin Wire Line (Ladder line, Open Line) - Surge Supressor

AS-309H - Open Wire Line Arrestor - Twin Line Surge Supressor. Needs ground connection.


These devices are used for protection of Radio Equipment attached to antennas.  They will protect from sand, rain, snow static buildup on antennas and feed lines which can damage sensitive radio equipment. They also will protect against damage from nearby and overhead lightning strikes.  And can mitigate damage to radios or large damage to 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 capability 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.

The AS-309H is designed for use with open single wire, or open twin wire transmission lines. They can handle Zo line impedances from 300 to 600+ ohms. The are meant to be mounted at ground level near the lightning grounding system.

Features:

  • Easy Installation, due to the flange with holes to allow screwing it to a plate
  • 4 kW CW / 8 kW PEP
  • Weather and water tight heavy duty enclosures using Stainless steel hardware
  • Safety rated and tested GDT
  • Includes SS washers and nuts to attach your ladderline
  • Includes grounding lug to easily attach to your ground system
  • Suited to prevent to prevent galvanic corrosion
  • Components are easily replaced
