I also installed a mobile phone booster/repeater last weekend which gives a 100dB boost to the signal. 1 bar 4G LTE will boost to full bars. As long as their is a signal, it can boost it. It will boost 3G, 4G and 4GX. I've not had chance to try the range out in the sticks yet, but in areas with a poor signal it works great. Full signal inside the vehicle, but I need to play around with the internal aerial placement so I can get a signal just outside of the vehicle . The external and internal aerials don't play well together and need metal separation. Not cheap but its mainly for work rather than weekends away. No photos as it's all hidden away apart from the antenna.
