>"circular polarization" to combat things like the Faraday effect
Another factor is that the antenna on a satellite can be in a pretty arbitrary rotation compared to the receiver on the ground. Circular polarization doesn't care about orientation. Further discussion here: https://ham.stackexchange.com/questions/12414/antenna-polari...
>Satellite phones and communicators are designed to direct most of the energy upwards towards the sky. Your existing phone does not
Recent iphones run 2x2 MIMO on mmWave and 4x4 MIMO on LTE. They should be able to do a fair bit of beamforming.
