The triangular-shaped trusswork towering above the Green Bank Telescope (GBT) is known as the feed arm, and it supports the subreflector and receiver room. Unlike traditional telescopes, the GBT's 200-foot feed arm is positioned off-axis to prevent blocking incoming radio waves.

Using the 85 Foot Tatel Telescope, Drake observed nearby stars Tau Ceti and Epsilon Eridani for a few months. Despite brief excitement over what later turned out to be an airplane, the project did not pick up any signs of intelligent life around those stars. 2/2

After radio waves reflect off the main dish, they bounce up toward the subreflector (smaller dish on top), then back down to the feed horns which focus the signals into the receivers below. Inside the receiver room hang the receivers and cables that carry data to the computers.

The turret can house up to 8 receivers at once. The feed horns vary in size based on what frequencies that astronomers are studying: low frequency = big feed horn, high frequency = small feed horn.
