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.
