We have just received letter that it may be necessary to reconfigure our dish antenna in order to still receive international programming (Polish channels) We were switched to eastern arc few months ago. Will I need an extra antenna? We are about to replace our roof in few weeks and I would like to know how much more time I have so I don’t have to call them twice. This will save us few bucks as well since I am assuming they are doing this for free. Any idea what is changing?
