Do you realy mean satellite antenna? Normal satellites not even weight 40 tones.

... may not stand in your backyard without you would notice them.
those dishes fulfill different functions
they could be observatories for a field of astronomy (radio-astronomy)
they could be there as up- or downlink antennas for communication with satellites and spacecraft which are on some mission, like cassini, or so
(see Deep Space Network --> NASA)
they could possibly standing around cause noone feels responsible for removing them after they are too old and no more in use.
satellite antennas of mass 40 tons and more possibly attract birds as a desired spot to sh** on, and look way stupid when they tilt over for whatever cause.

If you're asking about satellites in space, I know of no satellite that weighs 40 tons.
If you're talking about satellite dishes. One of the largest dishes on the planet is in Arecibo, Puerto Rico. The reflector alone weighs more than 300 tons.
