I only had about an hour to play with it but in a word, I would say WOW! I
used my DE-1103 to obtain the results. I tuned from 520-1710 counting all
the stations I could understand. Here are my initial results:

Without the TG-33 I received 45 stations here in San Jose.
Using the TG-33 inductively coupled to the 1103 I received 96 different
stations. That is more than DOUBLE! I haven't done any other kind of
testing yet. I will do more tomorrow.

I have a Radio Shack passive loop that I thought worked pretty well but this
is MUCH better. With the appx. 15 ft. cable you can get the antenna high up
in the air. The only thing it lacks is a way to attach it to the radio. I
used a small stick-on Velcro fastener to accomplish this. Maybe Degen will
include this later. I don't know how much this unit will cost but I would
suspect that it would be comparable to their shortwave loop antenna but I'm
only guessing.
