I have a Lacrosse HD Antenna that picks up most of the OTA stations great, but there is one that is driving me nuts. So my questions are these:

Do trees and houses block the signal like satalite tv?

When aiming the antenna I have it rotated to 38 deg as recommended by one of the websites but do I need to adjust the up / down pitch?

Thanks for you help.

Any object in your line of site between you and the tower is going to have impact on the stations you receive. The Lacrosse HD is designed for UHF reception, what channel are you having problems with?

Let me add, giving us your info from tvfool.com would be helpful also.

13.1 and 13.3 are the 2 I am having troubles with.

What info are you wanting from tvfool.com? My zip is 31093 if that helps.

If a hill is between you and the TV tower, you may benefit from tilting your antenna towards the crest of the hill as the waves will "bend" over the summit.

If no hills, level is fine.

The TV fool information will let us know the true RF of the station, distance from your location, and the expected signal strength at your location. Can you post the image of the results? (It doesn't show your exact address, it adds *****'s)

The main problems are 13.1's low frequency and low power. WMAZ-DT has a temporary home on RF channel 4. Small antennas like the Lacrosse always have problems with VHF-low channels. For another thing, VHF-low assignments are vulnerable to electrical interference. Fortunately, this interference isn't nearly as much of a factor on VHF-high, and especially UHF, channels.

All of which is why you may have better luck with WMAZ-DT after Feb. 17, when the station shuts down its analog transmitter on channel 13 and begins broadcasting DTV on that assignment shortly thereafter. RF channel 13 is much closer to what the Lacrosse was designed to receive. The station's power is also set to increase at that time -- perhaps substantially, if the FCC grants its application to maximize transmitter output.

Here is the image I hope.

As Don pointed out, your getting a double whammy of 1) the station being low power and 2) the antenna you're using isn't designed to pick up VHF and that station is currently broadcast on VHF channel 4.
