Signal antenna, bracket, and 50 foot cable
I climbed up on the roof and saw where I could mount the signal antenna with the included bracket. Instead of this approach, I simply zip tied it to a vent pipe I have on my roof. I then ran the cable, white 50 feet long coax, from the roof, down the outside of my house, in through a hole in my screen, and through the windows to my office area. I then plugged the coax cable into the base unit and powered on the base unit. I had earlier installed the base unit antenna. The base unit powered on and the indicator light turned solid green.
I took signal readings on my T-Mobile Galaxy Note II and a Verizon HTC Droid DNA before setting up the antenna and booster. After the zBoost DataBlast was setup I again took signal readings. I understand that the lower the number, the better the signal and that something like -60 is great while -120 is unacceptable. As shown in the screenshots, the T-Mobile signal went from -107 dBm (you can see why I use WiFi Calling at home) to a strong -73 DBM. The Verizon signal went from a nearly non-existent -110 dBM to -75 dBm. The bars are not a very good indication and sometimes lagged behind what the dBm readings showed. This is quite an increase in signal strength.
You can pick up the zBoost YX550-VLTE-AWS for $399.99. While this may seem expensive, if you have an office with several people who need a good cellular data signal or have a need for a strong cellular data connection then you may like the flexibility and coverage of the zBoost. Keep in mind that a stronger signal will also extend your battery life since it won't be hunting for a signal all the time.
