Abstract
The circuit of a portable, two-way radio is selectively connected to an antenna mounted on the radio or to an external antenna by a stripline switch. The switch has a metallic ground plate mounted on the radio, an insulating strip mounted on the ground plate, and a movable metallic plate mounted on the insulating strip. The movable plate is permanently connected to the mounted antenna, and is moved by an insulating plunger. The movable plate movably engages a pin terminal which is connected to the radio circuit and which passes through the housing of the radio for connection to an external antenna connector. When the external antenna is to be connected to the radio circuit, a plug with an external antenna contact is attached to the housing. The plug antenna contact engages the pin terminal connected to the radio circuit. A projection on the plug moves the insulating plunger which in turn moves the movable plate away from the pin terminal to disconnect the mounted antenna from the radio circuit.
