Bluetooth antenna provides insane range
What kind of range do you need for your Bluetooth to connect your phone to, say, a wireless headset? A few feet? Maybe more if you want to be able to wander around your house? Would 50 feet seem a bit excessive to you? What about 150 feet? Yeah, it would be tough to find a use for that, eh?
Well, if that seems excessive, get a load of this: an new antenna that provides a whopping 18.6 miles of Bluetooth range. Heck, you could go to work and leave your phone at home with that range. You could wirelessly transfer songs from your laptop to your phone from the next town over. I guess. And it's not some military-grade hack, either: you can pick one up for a mere $129. That is, if you can think of a real use for the thing.

WHAT A PILE OF CRAP.
Caveat #1: 18.6 miles, line of sight only. Put a toothpick in between you and your target, and you are cut off. Obviously, that goes for ordinary walls, too.
Caveat #2: The item pictured is not just an antenna. It is mostly an RF power amplifier, with an ordinary +6dbm antenna that can theoretically transmit up to 18.6 miles. Real world range is often half that, and only if you can accept a few dropouts per second.
Caveat #3: A +6dbm antenna is significantly directional, and therefore only useful in fixed base station applications.
Caveat #4: That RF power amplifier needs battery power, and lots of it. Figure on 100 times the battery of a regular cell phone/Bluetooth transmitter.
Caveat #5: And the real kicker: the item pictured only goes one way. Bluetooth communications are two way, unless you like just talking into the ether...
I am sooooooo fed up with assholes who lie to people, and get them all whooped up.
By the way, I am an Electronic Engineer with over 40 years of experience designing this kind of stuff.
