It's not suggested to replace them.
The antennas of Reolink C series cameras couldn't be dismantled.
As for other cameras, even though the antennas are detachable, it's not suggested to replace them with antennas of other brands, and we cannot guarantee the performance.
But if you really want to try the camera with other antennas or the antenna extension cable, you may refer to the below table about the requirements of the antenna.
