Alpha Delta Antenna Hardware Kits
Alpha Delta Antenna Hardware Kits contain one DELTA-C Center Insulator, antenna connection hardware, one model SEP arc-plug static electricity protector that is installed on the back of the DELTA-C, and two model DELTA-CIN End Insulators. These kits are a great way to build wire antennas! The antenna hardware is constructed using Alpha Delta's exclusive Model Delta-C Center Insulators and model CIN End Insulators. They're molded from Deltalloy, an extremely tough and durable plastic specifically blended to withstand sunlight and extreme weather conditions. An SO-239 connector is provided for a direct connection to the PL-259 on your coaxial cable. Or, a ladder-line balanced feedline may be connected directly to the dipole wire ends. If a balanced feedline is used with an antenna tuner in non-resonant applications, the SEP arc-plug must be removed to prevent the "false triggering" of the gas tube. The ALP-SEP arc-plug static electricity protector is a special gas tube component designed to bleed off slow-rising static electricity buildup generated by thunderstorms, high-wind driven snow, sand, or even a harmless looking cloudy day. These static charges have been measured to several thousand volts and can damage or destroy sensitive components in receivers' or transceivers' front-end circuitry. Note: When the "Documentation" tab is available, please look at the associated files for additional product information.

Alpha Delta Model LT Coaxial Surge Protectors
Alpha Delta Model LT Coaxial Surge Protectors provide lightning surge protection for transceivers on frequencies from DC up to 30 megahertz. Each unit features SO-239 UHF female connectors on both input and output. Every spring and summer, many pieces of amateur radio equipment are damaged beyond repair by lightning-induced voltage surges. An inexpensive investment in these Alpha Delta Model LT Coaxial Surge Protectors may be your best insurance to protect expensive HF equipment from destructive surge voltages! Don't sit by and allow surge damage. Order Alpha Delta Model LT Coaxial Surge Protectors from DX Engineering to put a damper on those surges!

Alpha Delta Coaxial Switch Replacement Arc-Plugs®
Alpha Delta Coaxial Switch Replacement Arc-Plugs® are designed to reduce the hazards of lightning-induced or other high-voltage induced surges. When hit with a surge, they will short to ground, protecting your equipment, and will remain shorted and must be removed or replaced in order to continue operation. As with all lightning protection; these surge plugs will not prevent fire or damage caused by a direct lightning strike to an antenna, power lines, or other structure. Alpha Delta D4 Coaxial Switch Replacement Arc-Plugs® are direct replacements for Alpha Delta Coaxial Switch model Delta-2 and Delta-4 series switches. As when used in Alpha Delta Coaxial Switches, D4 Replacement Arc-Plugs® are rated at 1,500 watts CW and SSB PEP, ICAS, at an SWR under 2:1. Lightning surges do lots of damage annually. Don't let your sensitive Amateur Radio gear go unprotected. Order Alpha Delta Coaxial Switch Replacement Arc-Plugs® from DX Engineering!
