The tuners in most HT receivers are afterthoughts and even with an outdoor antenna the reception will most likely just be ok.
A vintage receiver from the 70's like a Marantz 22XX series or a Pioneer SX series would work very well. You would just connect the receiver to one of your Onkyo's AUX inputs. These receivers are usually cheap to pick up and work well with indoor antennas. I live in a NYC apartment with steel frame windows and doors and this is what I do.
