KVH Trackvision in motion sat dish will become obsolete!

Take a look at the antenna itself and it should have a label somewhere with a number or manufacturer. If that doesn't work, take a picture and post it here for a good start on what you have.
You can also look at the controller inside and take a picture or give a good description and we can likely tell you what you have. It may just be difficult to give you an exact age.
