Back in the day...... the temperature noise equivelant on the preamps was about freezing, nowadays it's about -30. Thats why you can have a 2ft dish mispointed and still watch tv. The wavelength is about 1cm for full wave and its circular polarity so you need a 1/2 cm dia loop somewhere on top of the phone that's kinda omnidirectional for a gain of 1. That's standard sattelite, Elons stuff is different since it using dipoles that looked to be oriented horizontally
