If the existing sat phone is an Iridium phone, the antenna is most likely compatible, although there might be a cable adapter needed.
If the existing antenna is from some other satphone system operating in other frequency bands, I do not have any knowledge of the chances of it working.

Hi all I am looking at the Iridium Go and was wondering if those using it ordered the antenna also. I am on a 54 and there is an existing sat phone with exterior antenna could that work instead?
