is that a drum? - RadioReference.com Forums
Jan 23, 2008 · The "drums" are high performance microwave antennas with a fabric cover streached over them. They don't necessarly belong to a telco but they can be owned by any number of users authorized for that service. The "gate is an ice protecter; towers tend to ice up in the winter and the ice will fall in big chunks, simply protection from the ice chunks.
