AIS500 to AIS650

[PetrelMarine]

I need to replace an AIS500 with a AIS650 as I was told they cannot be repaired at the moment due to parts shortages.
The question concerns the re-use of the GPS antenna that was installed with the AIS500, can this be used with the newer AIS650 without the need for replacement?

I noticed the newer AIS650's have 50 Channel and the AIS500 had 16 Channel receiver capability. I am assuming however that because the antenna is passive this improvement is due to the improved receiver in the AIS unit, nothing to do with the antenna itself. Is this correct?

I just want to make sure it's the correct decision re-using the antenna if it's possible.
Thanks for your help.
