Bottom line: Went from a useless one bar to 4 or 5 bars. Calls would drop. G3 internet access took 2 minutes to load a page. We chose Wilson on its reputation. Now we have fast reliable access. My wife's office is 14 feet below ground, under three feet of steel beams, under a reinforced concrete parking lot. I ran 50 feet of PVC conduit and Wilson's cable above the ceiling (with owners permission) over and under the steel beams to the nearest outside wall. Outside had 5 bars. Tested unit with all 50 feet of the Wilson cable and had 4 or 5 bars on both Verizon and AT&T. I needed an additional 25 feet of 1 GHz Radio Shack low loss (7 dB per 100 ft) cable to bring the unit to its permanent position. Required only minor adjustment of the gain controls from the test positions. We have three bars out in the hallway, and three bars in the bathroom down the hallway, or almost 1000 sq ft of usable signal area. It took 2 hours to run the 50 ft of conduit through what looked like a Hollywood horror movie set, and 5 minutes to assemble everything else and adjust the gain controls. Good job, Wilson! Verizon customer service put me on hold for 20 minutes when I tried to ask permission to turn it on, as the Wilson manual required. Then Verizon wanted to get me an internet booster. No clue about Wilson cel phone signal boosters. Bad job, Verizon. The MyVerizon forum had a posting that approved consumer devices now have blanket permission. When I checked, the cel phone service at the outside antenna was great on both Verizon and AT&T. Oh, yeah. I'm an engineer, but I also have social skills, and a very happy wife.  :-)
