If you have no choice but to use the attic, you're starting at a distinct disadvantage. Use a larger antenna than your TVFR would suggest. The HBU-55 and Winegard HD7698P are single antenna solutions. The DB8E + Y10713 is a great combination.
If this is a case of 'WAF' (wife approval factor) I hope she will come to 'see the light' (or the TV signal in this case). If this is an HOA rule issue, the FCC is on you side... You have the right to install and use an antenna to receive OTA TV signals. The HOA rules are not enforceable (and they no doubt know it).
