You have a very well-documented and rational fear. Who can say for certain what these bi-directional digital dishes are capable of doing under today's massive broadband loads unless someone with a card from a federal agency were to come up to your door and guarantee, in writing with a signature in ink, that they are safe... and good luck getting that to happen? As a professional computer technician who, admittedly, is not too educated in satellite dish technology per se, I would not be so confident from mere hearsay that either the signals from the satellite are weak to begin with, that the bidirectional signal going out into thousands of miles of space during all weather conditions might not be powerfully concentrated at the source, or that incoming signal might not be being amplified to dangerous levels within the spatial cone of the dome, or any combination of all three. Basically if it's not something a person of average common sense would want their children to be running up and hugging on a regular basis, I see no reason why it should be allowed to be installed so low, yet I just discovered that they may in fact be. At least, for now. The very reason I found this discussion board was because I wanted to do research online into whether there were any federal regulations regarding safe height of satellite dish installations. The reason for my interest is because I was recently walking down a sidewalk when I walked past a ground-mounted satellite dish and felt a strange buzzing in my ear for that split second where I should have been in front of it. I felt this strange sensation before I knew the satellite dish was there. Once I started to inspect the outlay I realized that the cone was pointing directly where my ear should have been as I walked past it. What may come of this particular instance is still yet to be determined, but needless to say I understand your concern and would feel it myself if I lived under these conditions. To solve the problem, I would first ask the neighbor politely to have the dish installed higher up because it was making me nervous pointing towards my house. If they don't take action in a reasonable amount of time, say maybe a week, call the company that owns the dish, explain your situation to a manager, and ask that they do it for the customer pro bono because it is causing you extreme anxiety and emotional distress that is interfering with your ability to thrive and which may even be physically harming your family for all you know. If they refuse, consult a lawyer. It should only take a single letter from an attorney to both the homeowner and the company for the dish to be raised. Needless to say, you should start taking records now. Take careful notes of every time you speak to the neighbor or company about this issue. Make sure to write down dates, times, call durations, and names. Theoretically, your lawyer will need these notes to establish your case if it ever gets that far, which it almost certainly won’t. But having taken those records beforehand WILL help in getting the lawyer’s well-written letter sent to the offenders. It will make the lawyer know you’re serious.
I'm reading a lot of posts right now talking about how satellite dishes are “only receivers.” While this may have been true in the distant technological past, it’s impossible now, and I have to call such assurances from well-meaning satellite service installers "industry technobabble." If all the dishes did was receive, then you wouldn't be able to send even a one-word email using a satellite internet connection. You would not be able to switch pages in your browser because the satellite would not know what page to give you when you clicked on a link in a webpage with your mouse. As a computer technician, of this I am certain, and the signal would naturally get denser, and thus require more power, as more bandwidth was used for upload, such as during videoconferencing or P2P filesharing. As for television, I strongly doubt that you could even change the channel if the satellite didn't have a way of knowing when you pressed the remote, let alone rate a movie or order a pay-per-view. Online, I see plenty of information on bidirectional satellite dishes, so they do exist. I don’t buy the tech talk. I'd need to know far more information before I was convinced.
