Regenerative receiver schematic. The feedback was applied to the input (grid) of the tube with a "tickler coil" winding on the tuning inductor.

A good design will usually have low-impedance taps on the inductor for connections to the antenna and diode as shown in the schematic.

The antenna is a telescopic antenna that extends to two or three feet, the length is not critical.
