Response to Re: Digital TV

 

Yes, it was well known that low-band VHF (2-6) was a no-go for digital but most engineers thought high-band V (7-13) would be ok- but a combination of impulse noise (which digital decoders hate), phase-shifting (also a problem with digital) and late-night tropospheric ducting- which brings in distant stations to interfere has been problematic for high-band-Vs. So UHF is the place to be- especially in metro areas. Ironic since broadcasters use to hate UHF- but times change. VHF's longer range is still advantageous for stations in rural areas where noise and reflection (which causes phase shift) are less of a problem.
