Antenna Duplexer Circuit Diagram. But never say never , as Chris points out! Diplexers can be used in a variety of different ways Sometimes a very high Q resonant circuit may be used.

After the fm antenna amplifier circuit is constructed, the power supply should be connected to it. But never say never , as Chris points out! Fox Hunting Equipment: Fox Hunt Loop - UHF (PDF).
You must then test the DC voltage in the cable.
This circuit is subject to failure from electrostatic discharge.

Here will be used short circuit. A duplexer is a three port filtering device which allows transmitters and receivers operating at different frequencies to share the same antenna. The actual size of the antenna does not matter.
