Does it matter if the tv antenna points one way, or 180^ the other?

You guys, especially Dave, have convinced me that I need a better (and
thus bigger) antenna more than I need an amplified antenna. Does it
matter if I point an antenna with several elements of different
lengths to the station, or if I point it the exact opposite direction?
In my attic, it would be more convenient to do the latter. (I'm too
old and at least now, too fat to go on the roof.)


Also, I thought 50 miles was the longest range on level ground for a
transmitting tower of typical height and an antenna on the roof of a
two-story house.

So what about a claim that a Wineguard antenna has a range of 75 to 80
miles????

This antenna is rated for low-band VHF and I don't need that, I've
learned, but it's the mileage claim I am asking about.

Even this one says: Up to 60 mile VHF range; 45 mile UHF range Don't
they get that by mounting it on a 100 foot tower or something?

And isn't the info obsolete because digital transmitters are working
at lower power than analog did?

Thanks a lot.
