Hi everyone. New to the board, first post. I did a search regarding this topic but I wasn't able to find the answer to my question. I need to know if there is a device that will let me determine if a location has adequate line of sight for DTV. I will not have access to a STB or dish, just a footprint of where a dish would be installed. I most likely would not have access to a/c power as well. Is there anything out there like that? Any input would really help me out. Thanks!
