AS-303U - 3 kW CW / 5 kW PEP Coaxial Lightning Arrestor, SO-239 connectors, 1 to 70 MHz.
AS-300 Series arrestors are known for their reliability and performance. They feature easy mounting to plates, ground rods with our stacking bracket and also a convenient screw lug. The stacking bracket can be used on plates as well to save precious room in arrestor enclosures.
· Available in SO-239, Type-N, and 7/16 DIN connectors
· DC blocked, DC pass is available as a custom option
· Unique static bleed system with a UL approved Gas Discharge Tube, also ITU K 12 tested.
· This system usually prevents the GDT from ever firing unless a direct hit is taken.
· Saves your radio from static build up on large antennas.
· Models available for 3 kW, 5 kW, 10 kW and higher, details on website. Lower power available.
· FM low power broadcast model AS-303D FM
· Model AS-309H high-power single wire or ladder line arrestor, also DC block with static bleed
· Control line Arrestors for 8, 12, and 16 wires – 65V sparkover.
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) 300 Series coaxial arrestors, these arrestors have been improved in performance, packaging, and mounting 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 with simple tools. Due to the static bleed inductor 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 enclosures are machined aluminum small blocks which have convenient removable bracket to screw the device to a plate. We have also developed a mounting bracket system which can be purchased as an accessory to mount directly to ground rods, or plates inside enclosures, or a wall plate located at a coaxial cable entrance.
