I know the topic of onboard wifi/boosters has been done to death and back but even after reading dozens of posts and lots of reviews, I'm still confused. after and extended trip away, I found that I often had little or no signal on my phone for tethering my tablet. I have been used to this as most of my travelling is around Scotland and our phone network is pretty useless outside the main centres so I use local cafes and such. however my last trip was 6 weeks in England and I had not expected poor reception so often there. My question is - is there an aerial that will boost mobile phone signal and work as an internet source for a wifi router in the van or do you rely on wifi calling and a mifi type setup? there seems to be so many options and if I'm putting an aerial on the roof I would like it to be one that will do the job. asking 'the experts' at various outlets has confused me even more as they all seem to push their own set ups and , like dealers and payload, skirt the questions I ask. thanks in advance for any pointers
