"What Reasonable Results to Expect from
both with a variety of AM/MW Radios."

I think what Jay Allen communicates is that which some smaller
Radios with very small Ferrite Rod Antennas the Results form
using an External Loop Antenna can be . . . A W E S O M E !

Then - When other people use the same External Loop Antenna
with some larger Radios with very large Ferrite Rod Antennas
find that the Results are often only 'slight' : But never the less
there is some improvement in Signal and in Reception.
