Spider weave coils or basket weave coils are very high Q that's why the crystal set radio builders use them .Combine a high Q tuning cap (ceramic insulators) and this loop has very sharp tuning ,enough so that even at BFO setting like in LW you get a very crisp tune .
Also the basket weave coils have very little distributed capacitance ,some thing that has been talked about a lot when the first FSL builders were tweaking their designs.
Used inside most houses this loop suffers from noise as any very sensitive antenna does ,as far as i know nothing can be done about that ATM.
