Wow, what a difference. I used to have the indoor antenna. I had between 2-4 bars, and -80 to -90 gain. This is cut and pasted from my Caradlepoint MBR-1000. It is constant at -70 to -72.
Signal Strength (%): 100
Signal Strength (dBm): -70
My speed picked up a little, during peak Verizon times, and picked up to 1M at off peak. I couldn't be happier! I like dealing with 3G. You get EVERYTHING you need to make it work, as long as you follow their suggestions. Glad I bought this.
