The FCC protects your right to put up an antenna.
http://www.fcc.gov/guides/over-air-r...n-devices-rule Unless you live in a historic area or rent and the landlord forbids drilling holes you can put up an antenna. (Even if someone lives in a historic area or a landlord forbids putting up an antenna, there are still ways to put up an antenna, it is just a bit more involved.)

Do you need WCES, PBS? That impacts what you need for reliable reception.
