Well it took awhile, but I finally got the chance to take some photos of my Weboost installation in our 2018 27FB FC. As I stated previously, I mount an 8’ pvc pole to the side of my AS using the modified mirror/window carrier by Techno RV.
I routed the cable into the AS through the furnace access plate using a flat cable acquired from the DirecTV installer.
Once inside the AS, I ran the cable towards the rear of the trailer.
Underneath the street side dinette seat, I used Command Strips to attach the booster to the wall and powered it with an extension chord.
The interior antenna sits on the dinette underneath the wrap around window.
The best example I have seen this booster work for us was in Pala Duro Canyon State Park in the Texas Pan Handle. Camping in the bottom of the canyon, our AT&T coverage went from zero to 3 bars.
