in PENNSYLVANIA! HDTV signals are free, broadband and come from local Over-the-Air stations all over Pennsylvania. All you need to enjoy them on your HDTV Set, or old TV with a Converter Box, is the right Antenna. The type of Antenna you need depends on how close you live to the stations. Outdoor antennas cost about $300, but Indoor Antennas are cheaper for those living within 15 miles, or so, of stations. Antennas are CHEAP because they've been around a long time and you don't need a special HDTV Antenna to receive HD signals perfect, free and forever.
