25 is a closed oscillating loop antenna of any desired length, which for greatest efficiency, is run parallel with transmission antenna 19 of Fig.1.
26 is the connecting lead between the antenna and step-down transformer 27 of which 27' is the secondary.
28 is the lead connecting the secondary winding 27' to ground 31 via variable capacitor 29 and lead 30.
32 is the primary winding of transformer 27.
33 is a variable capacitor.
34 and 35 are frequency transformer windings, supplying current through leads 36 and 37 to motor 38, or any other power devices.
