Smaller antennas (top left) pick up signals from nearby transmitters. Larger antennas (lower left and above) need a rotor to receive signals from widely separated distant channels but can reject reflections from nearby objects.
Larger antennas need a rotor to receive signals from widely separated distant channels but can reject reflections from nearby objects.
A large high-gain antenna without a rotor might pick up distant
signals if they’re all in the same direction.
The same antenna (a large high-gain antenna without a rotor) will help reject signal reflections coming off of nearby objects.
