The device is similar to an ipod (no phone).

I used a passive RF sniffer around the case and found a sweet spot that
has significant RF output.

What I want to experiment with is a coupling loop over the case sweet
spot going to a coax and then a directional antenna.

It would be acceptable to simply scotch tape the loop on the case.

Any suggestions on the antenna would be appreciated.

You could maybe try one of those very large metal salad bowls from
WalMart as sort of a dish reflector.. It helped me considerably in one
situation. Good luck.

I used a reflector from a work lite and it seemed to help. I was able
to pick up the signal from a restaurant across the street maybe 200 feet
away. One of these. I think it was under $10. Knowing how cheap I am,
it may have only been $5.
