This device prevents HF signal currents from flowing down the inner or outer of the co-axial cable. L1 has a low reactance to HF or VHF signals, thereby bypassing the interfering current, whereas C1 and C2 have high reactance to HF and VHF, effectively locking signals to the receiver. L2 provides a further short-circuit (to HF and VHF signals) across the connections on the receiver side of the filter. Continue reading…
