A 127mm (5in.) long x 9.525mm (0· 375in.) diameter ferrite rod onto which a medium wave and long wave coil are wound. Coils may be moved on rod for best performance (then fixed with a suitable adhesive). Inductance of medium wave coil: 370╡H; long wave coil: 4· 1mH. |
Medium wave - 550 to 1550kHz (193m to 545m). |
Long wave - 150 to 280kHz (1070 to 2000m). |
