I bought a DT502 for the smart antenna feature, and finally got an RCA ANT2000 to pair it with. The RCA ANT2000 performs quite well for an indoor antenna (better than my decades-old attic antenna with a rotor that no longer works). The DT502's overscan issues really don't do the smart antenna feature any justice. I'm currently trying to figure out if any smart antenna boxes are any better, so if you have any experience with them (RCA, Goodmind, Alpha Digital, Tivax) please chime in. The DT502 also has other flaws...it does lock up and require a reboot, and the GUI and audio and video quality are inferior to the LG boxes (Zenith, Insignia). Also, the remote's range is TOTAL RUBBISH! So I couldn't recommend it, especially when compared to the Zenith box I have. If only LG would introduce a smart antenna model!
