I believe I’ve read (not sure) that uhf dhtv channels will eventually move to vhf? Can someone confirm this, and is there a source?
Thanks.
After analog gets cut off, some channels will likely move back to their analog allocations, including VHF, mostly the 7-13 range.
Some UHF antenna designs will work enough or VHF.
For a good DIY antenna look for a “Gray Hoverman DIY”
