I never knew there was a 14 story high rise in downtown Columbia MD. I used to service the Vantage House master antenna system there until the digital transition, but they never had me convert it to the new channel frequencies, and before that I had done antenna work for the Columbia Inn. Have you tried anything there yet? Baltimore of course has two VHF highband channels, which are a little "iffier" than UHF when you are in an apartment complex. It will take more luck than science to reliably get her Washington signals with an indoor antenna.
Did her building have an off-air antenna system that was never upgraded?
