Hello amtt81!! Do you have an attic in your house? As mentioned by Stephanie, you would be best served with an outdoor antenna, but the right antenna in an attic should provide reliable reception of the DC stations.
I live very close to you & have
similar signal conditions. Never had much luck with an indoor antenna, even on the 2nd floor with a window facing DC. Only managed to get channels 4 & 5 from DC & yes, all those international channels from Fairfax & Manassas. Strange how the only channels you get are the ones you don't want??? Go figure
An attic antenna works well here in Centreville & actually sees a couple Baltimore channels as well. The only issue is low flying aircraft approaching Dulles airport which can cause an occasional signal interruption
