Hi all, as some of you know i have been struggling with the internet lately our only means of internet is by a sim card in a router, we have a hill and a forest which interrupts our line of sight to the mast. Wondering if its worth getting one of these external antennas and sticking it on a long pole up on the chimney. Reading the boards and looking at loads of them on line i'm still not sure, just wondering if any one has had any experience with this. Its only until 2020 when we are promised some sort of decent internet
