On Friday I spent some time with a colleague seeing what a higher gain 4G antenna was capable of, whether it was worth the additional expense.  It took us a little while to check it out and mount the Sim card suitably and with the device on the floor I did a speed test to check there was anything there and I got 60 megabytes download speed!  So we mounted the device on the side of his house and although we could achieve faster speeds my colleague fine tuned the direction and eventually we achieved 88 megabytes download!  Please take a look at the video on my facebook page "Telephone engineer in York (All Mod Comms)", as I can't seem to load it on here.
