Where can I get relable information about the Digital Switch in 2009? - information about antenna

I have a TV that is currently in operation via an antenna. However, if the change occurs, do not want to upgrade to HD, or digital, as is our second home on television and is not often used. Does anyone know a website that has detailed information about converter boxes, and the government issued coupons?
