MW LW Coils and Rod Ferrite Rod Aerial, Loopstick Antenna with MW and LW Coils, 120mm long 3/8" 9.5mm diameter.

This is a single item of new, modern type ferrite rod antenna with MW and LW coils.  It is suitable for all crystal radio and other radio projects which require a MW (AM) coil on a ferrite rod and here you also have the option of experimenting with the LW coil for listening to Radio 4. There are separate main and coupling windings on each coil which are terminated in cotton covered wire which is solder tinned at the ends.

The coils are on formers which are movable on the rod. This gives you another way of tuning your crystal radio or changing the amount of coupling between the main coil and a separate antenna coil coupling. The inductance of the medium wave coil is 370µH and the long wave coil is 4.1mH. The typical coverage is medium wave – 550 to 1550kHz (193m to 545m) and long wave – 150 to 280kHz (1070 to 2000m).

The exact number of turns is not important and can be effectively increased or decreased by moving the coils towards the middle or the ends of the rod respectively.

The rod is 3/8th inch 9.5 mm diameter with two flatted edges which are 9mm across.  The wires are colour coded according to the diagram below.
