Make sure your antenna is solidly mounted. My antenna's base is set in two bags worth of concrete and bolted to the cottage. When I climb it I rope it off in three directions. Point one at the tower and one at Buffalo.
Get a cheap UHF-VHF combiner at an electronics junk shop (i.e. Active Surplus on Queen St. $1 ). Open it up and remove the capacitors and coils and wire the three poles together.
Tools are needle nose pliers and mini soldering gun. Seal up with hot glue.
In the City the roof top antenna is 31-39 feet above ground level which is 50 feet above Lake Ontario. The two Buffalo antennas are stacked and the two aimed at the tower are side-by-side. Either setup produces the same signal. The signal goes straight into the samsung 32 inch 1080P HDTV. A second experimental antenna(32') is in the corner of the yard and just sees the tower. There is an apartment building 40 meters across the street between the roof top antenna and the tower. Trees to the south have a minor effect on the signal from Buffalo. I'll try and post some photos later.
Where are you in Miss.? You should be able to pick up 17 and 23 regardless.
