Many years ago when I lived in an apartment, I was aware of OTARD, but did not want to battle with the property manager if I could avoid it. This was also so long ago that it was very rare that apartment dwellers had DBS.
Most people don't realize the look angle of a DBS dish is so high that it often easily clears the balcony railing even when mounted so low that no part of it is visible over the balcony, just as long as you've got a little distance between the dish and the point on the railing you need to clear. So I did a little aiming with a drinking straw, protractor, and compass, and figured out the lowest height I could mount the dish. Then I added a few inches just to be safe, but still ended up with a really short pole for my bucket mount, 30" or less IIRC. So the top of the dish was below the height of the balcony railing, invisible from outside the apartment, and nobody even knew I had a satellite dish. A year or two later lots of people got dishes, and made no attempt to hide them, as it turned out the apartment manager didn't attempt to regulate installs - heck, I saw some people drill mounting holes right into the wooden balcony railing.
