I too use the WILSON SLEEK CRADLE to sit my VERIZON MIFI 2200 unit in. This has an outside antenna and really makes my MIFI unit work alot better.
Also increases my WIFI generated footprint around my trailer. Being secured some folks come knocking on the door asking if I was the one having the strong WIFI footprint wanting to use my WIFI connection haha... Course you can....
When around the trailer the WILSON sleek is my MIFI docking station hidden behind my valance curtains going around the ceiling of my POPUP trailer.
Wouldn't leave home without one...
