Right Cellular Antenna Replaced

I have an A1455 iPad Mini with Verizon and I need to replace the right antenna (iPad mini & mini 2 Right Cellular Antenna) because I sliced it accidentally. According to this part page I should be able to use an A1490 but I salvaged a right antenna from one I had in shop and still issues using cellular.

Seems the device has been using cellular (usage data in settings) so I’m thinking I need to buy another right antenna.
