I don't know how big your attic is, but the antenna is about 7 feet long and 4 feet wide. You'd get most of your channels at a compass heading 301 degrees), so you''ll need enough room to rotate it to that position.
Furthermore, you'll need to try and keep the antenna clear of any objects (ducts, pipes, metal structures, etc.), so it might require a bit of trial and error to find the optimum location within the attic that gives you the best reception.
BTW, if you weren't already aware of this, the FCC has an over-the-air reception devices rule (
http://www.fcc.gov/mb/facts/otard.html). I understand the desire to minimize friction with your HOA, but in this particular case, you have the federal law on your side. It essentially boils down to saying that everyone has the right to install a reasonable antenna for OTA reception, and no landlord, HOA, city, county, or state law can prevent you from exercising that right. There are a few exceptions to this rule, so please read the document carefully.
Sometimes, just knowing that you have the law on your side is enough to help work out a reasonable compromise that everyone can live with.
