I'm looking for an SMB wall plate so I can wall fish my sirius antenna down to the back of my home stereo system. Anyone seen something like this?

Did you ever find any information?

I tried this not too long ago.

The best solution I found was to use the keystone plates and get a blank plate and drill a small pilot hole in the center and then use a larger drill to widen it out to be the size of the plug. It didn't look as clean as if I just had a real connector on the wall but it was pretty easy and looked cleaner than having a wire just come out an empy keysone jack or some other deal. Also, even if you were to find a plate you'd then have to hunt down a cable to go from the back of your tuner to the plate (these connectors/plates/cables weren't easy to find at the time I was looking into it).

Anyway, the 'drill a hole through a keystone jack' worked well and looked alright.

TTS makes one that you can install in any Quickport / Keystone wall plate.
