If you disconnect at the dish end (lift dish off the mount and gently pull and wiggle out), a 1/2 inch bit will work; otherwise, you need a much larger bit (1"+) for the router end connector. Start inside your house, at the router, and work your way back out to the dish.The fitting on the end of the cord that goes into the router is rather large and didn't want to drill a hole in the floor that big so I have it running in a window for the time being.
