I have been using a tp link 4g lte router with and external aerial for internet in a caravan in lincolnshire. In truth it was mainly running 3g as all mobile signals are rubbish in the area but it was still reasonable. With the impending switch off of 3g I have heard that 5g is becoming available. Any suggestions as to what kit I would need for best reception on a medium budget (under £200). Unlocked to all networks preferably.
