✪ "A different type of signal attenuation". Say what?

★ July 17th

I don’t think there’s even a question that the iPhone 4, because of its external antenna, is susceptible to a different type of signal attenuation than all phones with internal antennas

Wait, what the hell does this even mean? I mean, you could reasonably assume he meant the phone suffers more severe attenuation on that spot, but sentences later -- after describing a way to make the phone suffer worse signal attenuation -- he writes, "That doesn’t mean the iPhone 4 suffers from more or worse attenuation than other phones."
No. There's only one type of attenuation, which in this case means degradation of signal. If you touch or block the antenna, you degrade the radio signal that comes in and goes out of it. There's no difference to discuss.
