I've had near-perfect reception from Richmond stations as far as 80 miles away (Washington, VA), and still perfect 15 miles northwest of Charlottesville. In both locations I was on a ridge looking southeast, which helped, but was never affected by multipath issues. Often a smaller antenna works much better when that close.
