Uh, yeah. Show me that paragraph on the box of a "digital TV antenna."
I'm complaining about the fact that the consumer /must/ do this type of
research to find out that a "digital TV antenna" is not a better
product. How many people do you know--who aren't MythTV/video
junkies--who even know about antennaweb.org? IMHO, that's the CEA's CYA
so that the manufacturers of antenna can print whatever deceptive
marketing statements they desire on their products/product packaging.
After all, have you looked at how many antenna are labeled "digital"?
When I was buying my antenna, I was told by no less than 3 sales people
in the local area (i.e. who should know that there is a digital channel
in the VHF spectrum in my area--funny enough, also channel 2.1, but here
an NBC affiliate, on frequency 11) that I should buy a "digital" antenna
because it's smaller and because I'm not planning to use analog
channels. Fortunately, I knew enough to know that they were wrong (and,
of course, I didn't buy from any of the companies where they worked).
