I've yet to find documentation on which frequencies Cuddelink uses to talk between cameras. AI says they use 2.4 GHz, but based on the distance I've achieved between cameras, I don't believe it. They most likely use the 915 MHz LoRa band. If so, the multi-band antenna you linked, while not specific to that frequency, would probably work without causing any damage. Just be aware a severely out of tune antenna could burn up the transmitter. I would not be afraid to try it. Better than a damaged antenna or no antenna at all.
