Jackal830, I'm just adding in my two cents about WOI reception, and the lack of it. I also live in Altoona 50009, and in terms of over the air broadcast to a set top antenna unit, I haven't been able to pull the WOI (channel 5) stations for years.
I've considered trying to find a replacement set top antenna brand which actually could pull all the local broadcast stations including WOI, but it would be just too expensive to buy one then find out it doesn't do any better than my existing one, and then buy another brand, and so forth.
I rent, so I'm not at all interested in trying to install any exterior or rooftop antenna here. I just haven't been able to view ABC's local affiliate station WOI in all the time I've lived here.
This isn't a Tablo problem at all, in my opinion. It's apparently simply that WOI's signal type or strength, or both, is inadequate. And to me on my limited budget, my decision has been that it's sure not worth it to pay the monthly fees required for satellite or cable just to get one additional station.
