No need to worry about the HOA! They don't have the right to stop you in most cases, this is covered by federal law. Even if you signed deed restrictions!
See this link:
[Link: fcc.gov]What the above link says is basically... if you own the location where the antenna is mounted, or the location is your personal space... like a balcony, you are allowed to put the antenna up. Under very narrow circumstances can a local authority take the antenna down. It is up to the HOA or other authority to get a waiver from the government before they can force you to take the antenna down. (Unless they have evidence of a safety danger. Example: Mast close to power line.) Even if you must take the antenna down, you cannot be fined or charged for putting the antenna up. The law clearly states all the above points.
