Can you mount a satellite dish upside down?

It’s not always easy to find a place to mount a satellite dish. Drilling into the roof should be looked at as a last resort, because you’re creating an opportunity for leaks. There are a lot of different mounting options, but recently a customer asked me an odd question:

The only place I can mount my dish is under the eave, but I need to put the J-mount upside down. Can I put the back adjustment unit on upside down, or can I just mount the entire dish on upside down?

The question is pretty easy to answer with one of my favorite graphics:

Just, don’t.

It may be possible to frankenstein in a back adjustment unit so it’s upside down. It is a very, very, bad idea though. You’re changing the entire geometry of the dish so you’re essentially aiming it blind. Even worse, you’re aiming it blind and upside down.

As far as mounting the entire dish upside down, that isn’t going to work, period. You’re putting the LNB upside down and that means you won’t get any satellite but the central one… the others will be hopelessly impossible to aim. You could do it if you were able to use some sort of additional concave mirror, but I’m not sure where you’d put that.

A better option

You are much better off using an under-eave mount like this one. A mount like this will let you connect up under the eave, on a rafter, or on any a variety of different surfaces. It pushes the dish far away from the building, far enough that you should be able to mount the dish properly without bumping into the eave or the home. It is designed to work in a lot of different situations. Personally I have used this very mount and it works. I have used braces designed for a slimline dish to put it in place even more securely, and I know of installations that have been in place 7 years with no problems, even in severe weather

If that doesn’t work…

…it might be better to abandon the idea of an under eave mount altogether in favor of a pole mount, non-penetrating roof mount, or even a small tower. Chances are there are a lot more options than you realized when you’re mounting. No matter what your situation, there is an option and someone has already created it. There is absolutely no reason to try to mount a dish upside down.
