Wide band repeater coil with two coaxial windings - connected in series with same winding sense to connection point forming induction coil output

摘要

The induction coil has a core (1) on which a first and second two-wire line or coaxial line (W1,W2,W3,W4) are wound. The two-wire or coaxial lines are connected to the same winding sense in series. For the first two-wire line or coaxial line (W1,W2) the first conductor (W1) is connected at one end (1,3) to the repeater coil input (E). The second conductor (W2) is connected at the other end (5,7) to the output (A). The unconnected free ends (3,2,4) are connected directly or via a reactance (C1) to a common base point (M). ADVANTAGE - Has bandwidth of more than 5 frequency decades.
