“Why talk about acres"?

There are three reasons to translate our look at "field strength" into "acres".

(1)The first one is easy: the numbers would get too cumbersome if we discussed your possible signal coverage in terms of square feet or square meters.

(2)It's very easy to see that your signal can easily and legally serve a school campus or wilderness campground.

(3)And, if we remember that typical urban single-family home sites run from 1/4 to 1/2 acre on the average, it should become extremely clear that your obligation to avoid interfering with broadcast reception can easily involve hundreds of homes, before adding apartments!
