It's about seperate get Channels so that the bandwidth can be used evenly across the country(my best way to explain it, but someone else may have a better way). Again, you do not have to actually put the eA dish on, just tell them you did so they mark it in your account. Then you should be able to make changes online again. Anything you do online that requires a change work order completed(programming change, order something, tech visit, etc) it will want to change your "legacy" situation(the locals) to the correct Arc. If not completed, then you just lose features. You can also have it marked EA NLOS as well. But that may lose your locals all together.
