Helps prevent potential mismatch issues that could damage the antenna. 09130 OPTIONAL Advanced Lightning Protection (ALP) Module for SDA 100 electronic controller: Each driver chip has a relay in front of it that protects against lightning, nearby lightning incident and dead shorts. Module will only work if the antenna is not in the process of adjusting when the event occurs. 09132 OPTIONAL Remote Driver Board for SDA 100 electronic controller: The remote driver board is mounted near the tower base. 12 conductor control cable is run from antenna to the remote driver board, and then CAT5e cable can be used to connect from remote driver board to hamshack, up to 2000 feet away. Requires a power source. Advanced lightning protection (ALP) module is included with this option. Remote driver board comes with an aluminum mounting plate but does not come with an enclosure. stock photo 03122 Control Cable: 4 wire 22 AWG shielded control cable, outdoor rated, NON-buriable.
