Along these lines how would you get an Arome file from Squid when connected to Iridium?  I would use the Great Circle button when on a network, and SailMail for other GRIBS, but not obvious to me there is a way to get Arome GRiBS via IridiumGO.

Two more thoughts:

Carbon mainsails will interrupt ItidiumGo!’s dial-up and connection process, making it almost useless for data calls. I’ve seen this on boats with and without external antennae. The Go! would work with Dacron delivery sails but not the race sails.

FleetOne antennae ‘above deck units’ are available from multiple manufacturers.  The one made by AddValue seems to have the smallest footprint and weight.
