Outdoor antenna needed in Lansdale, PA
I'm really glad I found this forum. I need some help with HD both for myself and my mom and from all the posts I'm seeing I think I found the right place for answers (unlike my local RadioShack, which seems to have no correct answers for anything).
My antenna problem:
I bought my mom a Sony HD DVR (model DHG-HDD500) and a nice LCD TV to watch it on, and after I got everything set up we could see a handful of HD stations. The problem is that mom wants to get PBS (at least WHYY from Wilmington) and that is coming in pretty crappy analog SD, nothing digital at all. I looked at antennaweb.org and got *really* confused, because the result they give and what I see are rather different.
Here is what antennaweb gives for my mom's street address:

My first question is about the distances; they don't make much sense. Do the cities and distances bear any relationship to each other? If so, how is channel 12.1, WHYY, 14 miles away in Wilmington and at the same time channel 61, WPPX, 37.6 miles away still in Wilmington? The real problem is that I can't quite figure out why I get some stations and not others, based on that chart. The biggest head scratcher for me is WHYY and WCAU. Both are listed in "red" and at 179° and 14 miles away, yet 10.1 comes in great both analog and digital, and WHYY sucks analog and is untunable in digital. I tried an outdoor amplifier but that didn't seem to make any difference. The antenna is the typical rooftop affair, cost about $50 from RadioShack about 20 years ago and I'm willing to replace it if that will fix the problem. Another thing is that 6.1, near the top of the list, is very weak, but 6, 6.2, and 6.3 are all fine. Might the problem be elsewhere? Any suggestions will be appreciated!

6.1, 6.2 and 6.3 are all the same transmitted signal. It's unlikely that 6.1 is bad while 6.2 and 6.3 are fine. I'd guess that your antenna is not aimed perfectly and the differences in signal just happened at the time that you measured them. Try the test again.
Your problem is to figure out which way to aim your antenna. Unless you have a rotor there's too many choices.

It looks as if WHYY is currently running under special temporary authority (low power) at only 87 KW. They have a construction permit to go full power sometime in the near future.
This is often the difference in reception success.

How do find out how much power a station is transmitting?

Good luck and let us know how it works out with a rooftop. If it gets WHYY I may have to go that route. They do a lot of HD stuff!
