This is High Power four way RF switch. It is designed to be placed either indoors or outdoors in an additional protective box. The IND-I versions include a fan with a dust filter to improve cooling when installed indoors. This is a good idea when using higher power and digital operations. The fan can be disconnected (not recommended) or set to one of two speeds. The factory setting is slow speed. Switch is controlled by positive voltage.
It can handle up to 8 kW.
