These unusually shaped satellite dishes just outside the network operations center use a Simulsat (simultaneous-multiple-satellite) antennae that receive the TV signals destined for FLO TV from all the different channels at once. They can receive from up to three satellites and they’re programmed for 20 different transponders (the specific frequency and position for receiving an individual signal from a satellite). The low-noise block (LNB) receivers in the upper curved sections are more powerful and sophisticated versions of the LNBs in home satellite dishes and they can be moved automatically along the track to receive a signal from a different transponder. There’s a separate steerable satellite dish off to the side (not shown here) that can be moved to receive signals from satellites that FLO TV doesn't usually deal with, for special coverage and live broadcasts.
