constellation

Hello, I want to build the earth station to receive the signal of satellite constellation (like starlink, oneweb). Do you know the solution? Where I can buy the earth station antenna ?

Hi every one, PFD limit required for each satellite system to transmit the signal to the Earth surface. If I want to calculate pfd of starlink or oneweb satellite when I use a earth station receiving the signal of these satellite. Do you know the method? thank you all
