This circuit was found in a documentation from the 90's. Power is included, and the regulating integrated circuit must be equipped with a heat sink. L1 has 3 turns of wire 22 in the form of 10 mm with ferrite core; L2 has 2 to 3 turns of wire 22 over L1; L3 has 3 turns of wire 22 with 10 mm diameter without core; L4 has 5 turns of wire 20 with 8 mm diameter without core and L5 has 4 turns of wire 20 with 5 mm without core. To adjust, connect two 150 ohms x 5 W resistors as the antenna load.
