I truly love TV and I have six of them around my house. They are all plasma or LCD and the new broadcast will be no issue for me. I have one regular TV down at the boat dock and it will be affected. I will terminate it and upgrade that one.
Better apply for a couple coupons quickly: https://www.dtv2009.gov/ (step #3). Government is giving them away on a first come, first serve basis ($40 dollar coupon – converters will run between 30 and 70 bucks).
You’ll need one of these converters if your receive local TV signals over the air, and don’t have a TV with a HDTV tuner built in.
