FWIW
Directv tech told me that the HD reception issue with the small portable enclosed auto satellite finders (Kingflex ...et)
Is caused by the type and location of the Directv satellites themselves
He said that to receive Directv HD you have to use a satellite finder that has a larger dish than the small auto finder units have
I was using my standard home HD receiver and a tripod mounted 18" dish that I could fiddle with and receive a lot of HD and all SD channels while camping
But I recently decided to just go with the ease, speed and convience of the King Flex setup
and not worry about HD reception
Less tv watching equals more campfire time
I suppose that the older and lazier I get, simple is better :)
