The back side of board is devoid of interesting silicon, but we can't help but notice the strange silver jumper wire clinging to it. Hey wait a minute, this thing actually looks kinda familiar.

What's it for? You're welcome to inspect where it's routed and try to guess!

We think it may be a shielded diversity antenna of some kind, with a grounded exterior to insulate RF to and from the interior signal lead. The accompanying sticker NEW SAM could be labelling the wire as a Surface Antenna Mount.

That said, NEW SAM could be anything: Super Activity Monitor; Silver Aerobic Master; Slippery Agile Meerkat; Solidified Aerodynamic Meter ... The possibilities are endless. Leave your NEW SAM guesses in the comments below.
