>>> <It's a simple matter to provide converter boxes for legacy TV's. Digital signal in, old NTSC signal out, much like an expanded-channel TV converter. Under $100.> >> Or like the old UHF converter boxes for VHF-only TV sets (remember those?) But the "acid test" is this: Can digital TV signals be properly received using the old stacked-beam antennas with folded dipole driven elements that use the flat 300 ohm twin-lead "ribbon wire"? >>>
I wouldn't see why not. Once it's modulated with an RF carrier, it makes little difference whether its digital or analogue encoding. Unless it's some ultra-wideband time domain technique. >>> There are many such antennas still giving good service and their owners may be loathe to spend the money to replace them. (I think a 300 ohm:75 ohm balun installed at the TV set to adapt the twin-lead to 75 ohm coax would be sufficient. I prefer twin-lead over coax because it has lower signal loss, especially in long transmission line runs.) >>> Don't get me started! <g> I could go on an on talking about transmission lines, baluns, signal losses, etc. We'll have to have a chat off-list!
