Good information Pegasus!
Can you provide a link to the model you purchased? I just looked at their website and there are many choices?
I installed model number 470201 4GLTE booster (is was $329 on Amazon) and the wide-band marine antenna model number 304420 ($113 on Amazon). To use this antenna with this booster, a reducer coupling is required. I called Wilson directly (they are located in St. George) and put together my BOM with their help (they initially said this antenna would not work with this booster, but I worked with them and found the coupler to allow it to work). An imporant note - the 'inside' antenna that comes with this package requires the phone to be within a few feet of the antenna to work best - this works fine for my application, but if you want to carry your cell around a large boat and have the best signal you'll need to upgrade the inside antenna also - there are many options.
