Across the country? Yes. OTA will be messy for a while. See:
... Are many stations doing this? Why is this necessary?
The temp shutoff is necessary to replace the DT channel 5 tower with a channel 7 tower. They can't do all of this work with the transmitters operating. And this interruption probably wouldn't have happened if KETS had kept their original UHF channel assignment on ch 47, and if the katv tower hadn't fallen.
DirecTV receives KETS with an OTA antenna, so their signal will be off the air, unless KETS provides a backup feed. Contact KETS/AETN for more info.
