This filter also works on the 110 V grid. The capacitors are 100nF ceramic with voltages of at least 400 V. The coils are formed by 50 turns of wire 24 in a ferrite rod and C5 and C6 are trimmers (optional) that allow an eventual tuning of the signal that is causing problems. The circuit is indicated for the reception of analog TV in VHF and UHF.
