When looking at the transmitter profile detail am I supposed to assume my house is located at the right edge at ground level? How accurate is the topography? The reason I ask is that my house is located in an area that is about 1000ft above sea level. Do these calculations take that into account or do I need to add it to my antenna hight?

I am 53 miles 85 deg (west) of the los angels area towers. From what I can tell, there should be nothing blocking the antenna's line of sight to the transmitters yet the report indicates 1 edge for most channels. The towers are at close to 6000 ft and my house (53 miles away) is at 1000 ft.

I seem to get everything I want except KNBC (real channel 36). KABC (ch 7) is marginal but works at night.

Is it possible to know where my antenna is on the transmitter profile detail chart?
