Finally.
The Iridium Pilot sits atop the pole.
It has taken so long that I have mislaid two ground cables (where can they be, in a 35 foot boat??), but it feels like a major achievement to actually have it installed.
Next week I will set up the BDE (Below Deck Equipment) and put some money on the SIM, to test the phone and internet.
