Being able to tune in more stations would be better.... Perhaps. given what is on the air now days,,,I am not so sure.
However this is fact:
Tv stations have "Bands" the A band the signal should be clear and strong..> Even a low cost antenna should do the trick
The B band you need an outside antenna
And so on
Some locations are in the "Z" band (no reception possible, NO transmitters cover that patch of land)
The result is that you can not get more stations than exist.
How many stations exist?
Go to www.zap2it.com choose TV listings,, Enter your zip code and choose the last service provider (Over the air, broadcast antenna, forget which)
That's the list of what you should be able to get with a high gain antenna on a 50 foot tower. With a bigger antenna and a 100 foot tower... you can get more.
