Yes, they are all over the place, a few pertinent keywords will find them
with a search engine.
A key problem I've found is that a good antenna will be useful for day to
day watching, but is too directional to get all the channels with a single
scan. So if I have the antenna aimed for best distant reception (a
cluster of US stations more or less in the same direction), I may not get
all the local stations. If I aim for the local stations, I miss the
distant onces. Since the tv sets these days don't allow you to "program"
them, you can't enter all the tv stations you expect to find, and then
move the antenna as needed. You have to aim the antenna, scan, then
re-aim and scan for the other channels when you want them. Really
inconvenient.
Oddly enough, if I just put a loop on the tv set, placed near a window, I
tend to get more stations with a scan, though maybe not great reception
(lots of dropoffs). So the best solution is to take the tv set to a high
location with a loop antenna and try to get all the needed stations, then
go home and use it with a better antenna.
