Go-Video DPT100 Tv Tuner for DP8440/DP7040
Better have a strong signal.
The antenna and the rf to mini jack adapter aren't worth anything at all.  Plugging in rabbit ears or even attaching to a large roof top antenna still left me with a poor picture, even though this line has been plenty to get a nice picture on other sets.   Ultimately I had to run a powered inline signal amplifer to get a couple of channels to come in good, and a couple that are still barely acceptable.   I think if you are not planning on hooking this thing to cable or satellite, save your money.
