One of the first items that come to mind is, the FCC is on your side... have you read
http://www.fcc.gov/guides/over-air-r...n-devices-rule? HOA rules are not enforceable if they prevent you from receiving over-the-air television signals reliably.
Some times, 'less is more'. A smaller antenna such as the Winegard HD7000R or RCA ANT-751 aimed at the ION affiliate (Real CH-51) has a very good chance of reviving the rest of you 'must have' list, provided the antenna is outside and unobstructed by trees, buildings, etc.
Should that fail to give you reliable reception on one or more 'needed' channels, a more complex antenna system is possible.
