That is one of the new breed of commercial toroidial dishes. Small cable companies are using these and hopefully a quality smaller version will start to make their way into home use. Not the one from Wave Frontier.
Perhaps that is the future of satellite, special dish antenna's that will allow multiple orbital slots to be received with smaller reflectors, new satellites (with newer technology) and spacing the satellites closer together.
The particular dish in the picture is used by a cable system who has to look at aroung 10-12 satellites to provide their programming.
Some cable guys perfer individual dishes to get programming, with them you get less adjacent satellite interference and do not affect other sats when woring on the dish. There are also multibeam satellite dishes that will get from 1 to 6 satellites on a traditional dish. It is all user preference.
If you want one of these for Chirstmans PSB you had better have a fat wallet. They go for 60-80K depending on options and that doesn't include installation. I have no desire to point one....
I once spent about 4 hrs of laying on the ground yelling suggestions to a guy in the bucket truck on how to switch the feeds around after working 24 hrs straight to get a cable system back online. We had some bad info on which sat was on which cable and were trying to straighten it out so we could get the people all of their channels. It was not a morning/afternoon I will soon forget. I learned my lesson about pre planning and not trusting some one elses info. But anyway it all worked out in the end and the people had their tv to watch.
