The patented and proprietary gas tube construction has an integral failshort mechanism for a power-cross condition that shunts both your cable’s center conductor and sheath for a common path to ground. The protection element resets af er each over-voltage incident. DXE-RLP-75FF Receive Feedline Surge Protector, 75 Ω, DC Pass, F Connectors .................................................$22.99 Utility Enclosure Package The Utility Enclosure Package is a high-impact thermoplastic enclosure ideal for outdoor mounting of all types of lightning protectors or other equipment. Its weathertight design protects the components from rain and direct water spray. It resists degradation from environmental contaminants, chemical fertilizers and insecticide sprays that can ruin metallic housings. The thermoplastic housing and wire entrance grommet material are fire retardant and UV stabilized. The enclosure can be painted with latex or oil base paints if needed to blend it in with its location. The kit includes an aluminum mounting plate for attaching your lightning protectors and ground strap. Mounting hardware, mounting plate and four weathertight large feed-through grommets for RG-213 and LMR-400 sized cable are included. Optional feed-through grommets for smaller cables are available.

The conversion makes them easier to mount inside DX Engineering’s UE-2P Utility Enclosure. Hardware is included. DXE-ATT3G-BRKT Flange Mounting Bracket, Straight ............................... $10.99 DXE-RCT-BRKT Flange Mounting Bracket, Right Angle ........................... $9.99 Transi-Trap Broadband Coaxial Surge Protectors These gas-tube surge arrestors protect sensitive equipment from excessive voltage and current caused by static buildup or a lightning strike. The 50 Ω DC voltage pass-through design is perfect if you’re using coaxial cable to carry both RF and DC voltage, like in an antenna switch. These protectors use a replaceable Arc-Plug™ cartridge that you can change in the field without tools. They feature a 1/4"-20 mounting stud for easy installation. The Defense Logistics Agency has assigned an NSN of 5920 01 5470278 to the model TT3G50 Coax Surge Protector and NSN 5325 01 5466841 to the 3G50 Arc-Plug cartridge for use in all U.S. Military and NATO applications worldwide.
