said by Anonymous_: does nasty things to the reception of the DTV broadcasts
I have no problem with our Access Point, or separate router, or any other electronic gear for that matter, interfering with Over the Air TV.
Given that OTA uses much lower frequencies (VHF 55 - 211 MHz & UHF 471 - 693MHz) the problem is probably not due to Wi-Fi radio but radiated or conducted noise from the box itself.
At far as the pros and cons of DTV vs analog and different types of DTV modulation, we live in a rural area with a roof mounted antenna, have good reception of both NH and Boston station and due to sub channels many more TV channels then before. We were also lucky that the NH stations are on VHF and the Boston on UHF. That means by using separate VHF/UHF antennas we no longer need to use a rotor.
