Benet
is solution provides a low height, high current
solution to exposed set-top box applications.
Objective
is solution is designed to oer surge
protection to the RF input port from a
set-top box to a satellite dish. Lightning
strikes or near strikes to the building can
damage the delicate RF port and the power
supply which is fed to the dish.
