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?
