The same way you guys do. I'm looking at strength of signal on his chart. And then I recommend my favourite which is what you guys do. And if it don't work, oh well, it's a special condition caused by an unlucky set of reflections in the area.

I definitely wouldn't buy anything that wouldn't allow for a full refund.

I would recommend the guy buy what was convenient and use the signal meter on his HD-TV to figure out the rest. Sony and these companies put a lot more money and engineering brain power behind their tuners and the signal meters then has been put into TV antenna design for decades now.
