I have a question in mind regarding transmitters and receivers. Let's say we have a dish then a coaxial cable connecting our dish to the TV. Can we consider the Dish as a transmitter \$T_x\$ and the TV coaxial input as the receiver \$R_x\$ ? Will the signal passing through the coaxial cable (our channel in that case) be simply the analog electrical signal but amplified? Or is there some intermediate processing?

The thing at the focus point of your satellite TV dish is called LNB; you might want to look up what that abbreviation stands for ;)
In short, amplified, pre-filtered and mixed.
