Transmitter leakage

特許 係属中 All equipment using RF electronics should be inside a screened conductive box and all connections in or out of the box should be filtered to avoid the passage of radio signals. A common and effective method of doing so for wires carrying DC supplies, 50/60 Hz AC connections, audio and control signals is to use a feedthrough capacitor, whose job is to short circuit any RF on the wire to ground. The use of ferrite beads is also common.
