I need to get a good internet connection into my shop. I do not want to hard wire it between the buildings as there is no way I am hanging a cable overhead and I have concrete surrounding the house and shop. The shop is a metal building with an outside layer of metal, 6" of insulation and then an inside layer of metal. I barely can get cell phone service in the building and I live near a tower. I am thinking point to point antennas are the way to go, but don't know where to start. The distance is not far, maybe 75', but the structures make it difficult. Anyone have any experience with this type of setup?
