摘要： A conducting housing (to be closed by a lid) for a coaxial cable distribution network has a common port and one of an aerial or pedestal port. A motherboard carries an RF circuit and a transfer switch. In one setting of the transfer switch the RF circuit connects a coaxial pin at the common port with a coaxial pin at the pedestal port. In the other setting the common port pin is connected to the aerial port pin. When the aerial port is used on a rectangular housing, a transmission line forms part of the RF circuit between the motherboard and the aerial port. The transmission is preferably a central conductor spaced over most of its length by air from an outer conductor in the form of an inverted U enclosing the central conductor on three sides. Preferably a ground plane on the back of the motherboard connects to the transmission line outer conductor to provide a path entry in the housing at both ends for ground currents generated by signals in the RF path.

摘要： A housing for a CATV circuit board has exterior cable pores and stations for connection to a circuit board. Flexible coaxial leads allow any port to be connected to selected one of a number of stations. The stations may be composed of a horizontal flexible lead and a vertical terminal for the circuit board. The position of the station may vary within a preset tolerance to facilitate connection to the circuit board. End sections may be provided at the ports and provided with means for separating or combining the RF and AC signals. A tray for seating in the housing and for receiving the circuit board may be shaped to ground the outer conductor from a station and forms also the ground for the circuit board.
