In March I picked up this cell phone signal booster at a neighborhood yard sale. It was $10.00 and worked when parked

It didn’t come with the small transformer power supply

With a little research, and $13.00 shipped, I had one in hand. March and April were very busy and not in a good way.

Yesterday I assembled and tested it. With all shop doors shut, I had very good signal in the entire shop. Even in the office with it’s walk through door shut. I actually had better signal than no booster with all doors open.
So I installed it. It took about 5 hours to get a spot to pass through the exterior wall. Then another hour to complete the rest of the installation. A chore that will pay great dividends this winter.
