The flexible pads are called base-isolators, whereas the structures protected by means of these devices are called base-isolated buildings. The main feature of the base isolation technology is that it introduces flexibility in the structure.
The greater the isola-. tion value, the less interference. from a signal on one port rela-. tive to an adjacent port. The. amount of isolation is directly. affected by the VSWR present-. ed at port 3 of the isolator.
