Ours is a Wilson but old (2013 - pert near ancient for electronics). We spent hours on the internet confusing ourselves before John finally called Wilson, who were extremely helpful. We wound up with a trucker antenna on the rear, thin net coax cable run from there, up passenger side, across the cap, into cabinet over driver's head where booster/repeater and home/office antenna are mounted. It works... Not as fabulous or aggravation free as we'd like but it works.
Main problem is distance between the two antennas. Equipment wants 25 feet minimum between the antennas - not happening in a 2552. Solution is repositioning the inside antenna and dialing down the power until it stops creating a feedback loop. We do this every time we use the unit - we adjust until we hit the sweet spot. Our unit shuts down when it detects feedback to avoid causing issues with the cell towers. You MUST have this feature. It might be standard now due to FCC rulings.
The cable on the inside antenna is long enough to move it over near passenger window for better broadcasting to the picnic table if incoming signal is weak. We have a Command cable bundler mounted in the cabinet next to the inside antenna to quickly control that long cable when not in use.
Our booster is only 3G while our mi-fi\hotspot handles both. They came out with 4G boosters the next year but the over-$1,000 price tag for just the booster/repeater helped us wait. We will probably upgrade to a dual 3G/4G LTE soon.
Ron is correct - the unit is actually a repeater; it takes whatever signal your outside antenna picks up and feeds it back out closer to your phone. No signal means no signal. However, weak signal may get you text messages and sometimes a phone call as we had in the Okeefenokee Swamp. The rangers wanted to know how we did it because they had to use radios since no cell phones worked there... Until ours. We are able to connect most of the time as we wandered the country.
We use the Wilson system and a Verizon mi-fi/hotspot with Verizon service. Place the inside antenna, kick on the booster, adjust the signal strength to kill feedback, set the mi-fi on the picnic table and power up the computers. Our phones get signal straight from the booster as does the mi-fi. Computers link through the mi-fi which gives us a faster connection than linking computers through the phones.
