Comparison of three indoor active antennas
 

I have a SONY An-Lp1 antenna that I occasionally use in conjunction
with a Sony ICF-SW77 receiver. This combination works pretty well, but
I'm wondering how big an improvement I'd see by using either (1) a
Kiwa pocket loop or (2) an AOR WL-500 window loop. Can anyone compare
one or both of these antennas to the AN-LP1 (or to each other)? I
don't want to plunk down another two hundred or so bucks for an
antenna unless I know it's going to be a significant improvement.

Thanks for your help!
