Samsung TX-P3075WH, mystery part?, OTA signal strength meter

Hi Guys, I recently purchased this Sammy and had a couple questions. First can anyone tell me what this mystery part is that came in the baggy with my remote and manuals?(see pic) It appears to be a magnet of some sort, the hole through the center is about the diameter of a AA battery. The part says TDK on it.
Second I am using a CM 4228 with a 7775 Pre-Amp and live about 34 miles from my transmitters. When I check the signal strength meter I am getting 4 out of 10 bars for most channles and 5 out of 10 at best. All the channels are fine, no drops or anything like that. I am just curious as to what others with a similar setup are getting on the signal meter.
Here's a pic of the mystery part:

I'd say it was a toroid of ferrite (an iron oxide) meant to prevent interference radiating from an electronic device. I'd say it was the same diameter as some cable you got, meant to be clamped around it... Similar to the 'lump' found on VGA cables, meant to keep EMI inside your computer - otherwise the whole cable can become a transmitter antenna.

thanks for the info....but the TV didn't come with any cables.

Ferrite absorbs magnetism & associated electromagnetic energy... it's on the surface of the Stealth planes to suck up radar... I'd say if you get fine grained interference on your DVI or HDMI input, try clamping this on near the output of the source device.

The manual includes information on these devices, known as "Ferrite Cores".

From page 18:

"The ferrite core is used to attenuate undesired signals. When connecting cables, attach the ferrite core to the cable near the connector."

Right. The ferrite cores are to be used with any cables you need to use them with. If the TV came with cables which needed ferrite cores, they probably would have been manufactured with the cores included with the cable, like most computer monitor cables.

Unfortuately, Samsung does not provide any more information on just what type of inputs might benefit from using the ferrite cores.
