In my case, I only have a 4w handheld I can use in the house, and it's a townhome community so I'm surprised I can hit it even outside with all the obstruction. I'm near the Wegmans in Fairfax, about 1 mile west of the city line. And yeah, almost 10 miles exactly from the Seven Corners location. I'm not sure why they haven't renamed the repeater in the listing.

I think it performs great, but I'm relatively inexperienced. Lots of power and people can hear me loud and clear on repeaters 10 to almost 30 miles away (the farthest I've tested).

Nice setup! I'm in northern Virginia also (Fairfax) and may do something similar. I can hit the Warrenton and Alexandria repeaters from outside, but not inside.
