put it anywhere near your TV or MythTV box.  The MythTV box is already
plugged into your network switch anyway.  Hide the HDhomerun in a closet or
the basement.

Though if you are planing on running your MythTV box on a wireless network
it probably wont work.  Personally I can't stand wireless.  It only takes
one weekend of hard work to run a cat5 cable into your TV room.  Heck there
is already a coax cable going there.  Just follow the same rout as the coax
wiring.  Thats what I did.  With awired network there is never any signal
drop outs or interference or reduced bandwidth or etc.
