This antenna is a three-frequency composite antenna. It operates in:

• U band 1 (225-678MHz)

• U band 2 (225-678MHz)

• L band (1300-1950MHz)

The antenna radiating elements are distributed with upper and lower poles. The U band elements are located at the bottom and top of the antenna, while the L band element is in the middle of the antenna pole. All elements are designed as half-wave dipoles and utilize L-C matching networks to achieve impedance matching within their respective bandwidths. The upper U band section of the antenna is designed to be detachable for easy storage. The antenna exhibits high radiation efficiency and strong environmental adaptability.
