Simple two capacitor isolator
This circuit is a simple isolator for TV and Radio antenna connection. This circuit passes radio frequency signals nicely, but does not pass significantly 50 Hz signals, so the ground loop is eliminated. The circuit can be easily built into antenna connector or to a small box. I would recommend to use small metal box, where you connect one of the antenna connectors to the metal box and isolate other connector from box. Metal box allows mechanically strong construction and provides good shielding against radio interference. The capacitors in the circuit should be rated at least
250VAC (400V DC) to make sure that the adapter with stands situation when antenna network ot television/radio is floating at mains live potential. Antenna isolator circuit diagramDakle, sto mi tocno treba za sloziti ovo?
