This the same “boost your signal by 300%” antenna that you see advertised on TV infomercials for $19.95 to $29.95. We hate TV infomercials. After seeing all the miracle car waxes and get rich quick products, many of us immediately laugh at their outrageous claims. Since this product was mobile phone related, we ordered some for testing a few months ago. Our expectation was to find it totally useless (just like the “it will protect your car paint from a hot blow-torch” car wax.) Instead, we found that it does help the signal, though not nearly as much as the hype claimed it would.
