The cell phone booster industry is going through some pretty radical changes right now with the FCC. If a booster is installed improperly it can create havoc with users in the immediate vicinity. There seem to be two major players in the market: WeBoost and MaximumSignal. There is a pretty extensive thread over on Escapees here:
MaximumSignal Update? - Internet Access on the Road - Escapees Discussion Forum
Both units are rather expensive but take a look at the current in-home wifi setups today....$300 is not uncommon. After a lot of research we purchased the MaxSignal combo unit and are reasonably pleased. It won't do magic but gives us the boost needed to get a signal to stream with in most cases. The RV unit we purchased gives us boost throughout the RV - not just a few inches from the antenna.
