A:Answer Not really. The dots showing signal strength are quite arbitrary and too granular to show a 1.5x performance increase. A 1.5 times increase in signal is a 1.76 dB increase in decibels (10*log10(1.5)). To see this you need to enable the field test mode (just do a search on this to do that). Then the phone shows dBm (decibel milliwatts). -112 is weak, -92 is good, and -82 is great. Then you need to go to several locations and measure power with and without the Reach antenna on. I did this and found it difficult to observe any increase. Truth be told, 2 dB is still a bit too fine to measure. I found the phone only showed 3 dB changes, which is 2x.
