New antenna location and polar range rings

[Jose Vazquez]

Hi All!

I'm planning on moving my ADS-B antenna from its current position to another, which is higher. I also wanted to compare coverage and thought about taking a screenshot everyday (or twice a day) with range rings and range chart on, to compare them to those when the antenna is on its new position.

Is there a better way to do this? What is the rage of each ring? (assuming 50 miles)

It's not a range ring, but the graphs are still useful for comparisons:
