Looking at an image of the Weeboost system with antenna online, I see that this is a trucker's mirror mount antenna. The clamp with the transmission coax is made to attach to a tubular support on a semi truck mirror. You might mount it to the roof ladder, but permanently mounting the antenna at trailer roof height can cause bridge/tree clearance issues going down the road.
I have a triangular-shaped yagi antenna for my cell amplifier, and came up with 2 - 10 foot pieces of different sized conduit that telescope inside of each other. I use a hose clamp setup to secure the extension, and stand up the entire mast on the inside lip of my desk slide. I use C clamps to attach the mast to the slideout lip while set-up. The collapsed mast fits on the floor at the dresser end of my bed when traveling.
