An air conditioning system provides air to an enclosure associated with a satellite antenna that houses an amplifier or other electronic component. The air conditioning system supplies conditioned air to the bottom of the enclosure and receives return air from the top of the enclosure for improved airflow. Various implementations may also provide redundancy through the use of common supply and return plenums, or other features. In some embodiments, the air conditioning system may be conveniently retrofit onto existing satellite antenna installations to provide improved efficiency and redundancy.
