Get one about 40 foot square on a 100' mast. I don't know anyone around here can pick them up, even though they could pick up 6 vhf stations over the air in from a 90 mile radius before.
The only station anyone and everyone in my area can pick up are three channels of public television... one in spanish. Since when does public television broadcast with more power than commercial?!?
I e-mailed the local station and asked if they planned on increasing the power after analog goes down... and didn't even get a reply.
Apparently this is how it works: you buy a converter, maybe an antenna, find out you can't get anything, and then go pay somebody... cable or satellite... for a subscription for fewer local stations than you had free over the air.
I'd say it's a big money suck. Why am I not surprised? I'm gonna have a cardiac from not surprise.
