I have had mixed results with my Iridium Extreme Sat Phone using the standard antenna, and the supplied small "puck" antenna placed outside doesn't seem to have any effect.
So, I am contemplating buying an exterior antenna, hopefully this will provide more reliable service.
What recomendations and experience do readers have?
Thanks.
When we purchased our Iridium 9555 in 2010, we also ordered an external antenna as an option. Mounted on our pushpit, we never had any problems connecting to a satellite. We now own an Iridium Go and it works fine with the same external antenna.
