Alienworks does and doesn't
I was at the show and visited the booth and display of the flat panel antenna.
The construction was somewhat quality, and somewhat "not ready for commercial sale". It appeared to me to be a technology before its time. Had the antenna been twice the size of that on display, the pictures would probably have been acceptable.
Don't have time for a complete discussion right now, but the flat panel works, just not good enough to pay anything for it. I spent about an hour watching the 13 inch monitor, and there was visible sparkle and crackling audio on a scrambled channel.
An unscrambled channel on another satellite did not have noise in the audio, but on a 13 inch tv, I would not trust the naked eye to verify signal quality.
Those running the show were not letting anyone put any kind of meter on the antenna. It looked promising, but I would want an antenna with a better margin between bad pictures and excellent pictures, and I would want an engineering test of the antenna, proving it was engineered properly and could do the job it was designed for.
