Review on Eightwood Antenna Compatible Cellular Wireless by Angel Caldwell

I bought this for the hot tub! My 6 month old hot tub had an expensive Smarttub Jacuzzi App Control addon. Although they paid $600-$700 for this innovative feature, the antenna was not included. It was hit or miss with the app in terms of changing the hot tub settings. I checked and the smarttub module had an antenna input that fits this antenna. I bought and installed. The antenna seems to have solved my problem. The only warning is that the threads are fine. Be careful not to cut the threads when installing this antenna.
