The FCC is on your side... the covenants and zoning rules are superseded by the OTARD rules.

However, if you want to fight the drawbacks of an attic install, you could go with a 8-bay panel antenna such as the DB-8, U8000, CM-4228 or HD8800. The 4-bay DB-4e also is a strong contender. Face the antenna toward ENE. If you're satisfied with the top six stations (green) on your TVFR, you probably won't need any amplifier. (Antenna gain is always better than amplifier gain.)
Add a UVSJ and an Antennacraft Y10713 if you want to see WINM.
The Antennas Direct CPA-19 is a good low-noise preamp that is able to handle stronger signals. Another option in an attic install would be a Channel Master CM-3410 or CM-3414. Again, use an amp only if your are intentionally trying to receive the weaker signals.
There are some UHF/VHF combo antennas that would be worth consideration as well. I'm sure there will be others wanting to weigh in.
