Verizon has a code you can dial to change your bars to an actual dba reading (google it to find), the lower the number the better.  I was around 92 dba.  With this device installed, i dropped down to between 68-72 dba.  Great product!  The absolute most important part of the installation is LOCATION.  Just a very small turn of the antenna makes a big difference.  I installed my on a 6' tall steel pole on top of the house.  I stood on the roof with my phone, I turned ever so slightly until I found the best dba direction, then I pointed the antenna in that direction.  The inside positioning of the booster and receiver makes a difference as well, but what i found is the outside antenna is where the big improvement will come from.  And yes, I live way out in the sticks.  No internet other than Hughes, so now we have Verizon hotspot and with the booster, we are at least double the speed we were with Hughesnet.
