Well, come join us in the FTA area. We get great looking content for FREE! Just equipment costs, and you can usually find dishes for free if you look hard enough. IMO, it's an awesome hobby...and it pays for itself over time. With my OTA antenna and FTA dish, I'm happy. I get almost all the college football games on the weekends for free. And it looks alot better than D*/E*.
Anyways, I would make the effort to install an antenna in attic atleast. Indoor antennas work SOMETIMES but aren't always that great when weather conditions get bad. They're more reliable and stable. And, plus, you can get far away stations if you're lucky. I have my antenna about 20-25ft in the air...works great and no amp on it either. I can turn it and get WBTV in Charlotte which is over 100 miles away! And it's not even as big as the 4228!
