Lastly as others have mentioned this thing gets VERY VERY Hot

This thing really works

Forget the mounting stuff it comes with this is so much easier and keeps the thing cool

Best thing is that they are all portable and work just as well in the car

The numbers are all with a negative sign in front of them but the main thing is the higher the number, the lower your signal strength

He reports a solid 4 bars inside his cabin along with fast 4G data service, and this with the included mini antenna temporarily sitting on top of the boat's arch

it did not boost the 3G signal at my physical location, my phone goes in and out of 1X to 3G, I had hoped it would stabilize the 3G for voice and text, but it did not do anything that could be seen.

But for the 3G phone this works great.
