A loop aerial/antenna can work fine with a regen BUT not as part of the detector tuned circuit. Use it as the source for a simple RF stage and then couple that quite lightly to the detector.

.....a loop as the inductor of a regen (especially one oscillating for CW reception) is really a recipe for dissatisfaction with the receiver. ?eceive frequency will be unstable in more than way!

A regen receiver relies on being on the edge of oscillation. Any extra tuned circuits coupled to the transistor will pull that off frequency, and likely cause it to shift between the resonant frequencies of the two tuned circuits.

A regular antenna is only a very broadly resonant thing, or a random piece of wire. A loop antenna is generally tuned with a very tight resonance.
