Our WEBOOST RV-X booster has made it possible for us to keep secure internet access in these remote areas.  The antenna is raised as high as possible (we used a telescoping swimming pool cleaning pole).  The antenna signal  (Cell and 4G) goes down the cable to an amplifier and is then transmitted into the RV.  we have a Verizon Jetpack Hotspot mounted near the inside transmitting antenna...it uses the Verizon 4G and turns it into WI-FI to feed our devices.  We have been getting up to 25 MBS download speed here at Buckskin Mountain State Park.  Without the booster we would not get much at all...if any!
