The homemade DTV antenna has been assembled and installed. Everything seems to be working well. All the local channels tune-in just fine. My TV doesn’t display signal strength, so I don’t really have any way of knowing if the signal is any stronger compared to the rabbit-ears. But it does get rid of the ugly antenna in the living room.
I placed the antenna in the attic above the garage and set-up an A-B switch to allow switching the living room TV between antenna and cable, should we ever subscribe to Comcast again.
Larger washers might be helpful, but other than that, the Make instructions worked out well.
