A 6-dipole FM antenna system is a high-performance broadcast antenna designed for FM radio transmission within the 87.5 – 108 MHz band. With 6 vertically stacked dipole elements, the system provides enhanced directional gain, broader signal coverage, and efficient radiation. Built to handle up to 2kW of continuous RF power, it’s ideal for medium-sized radio stations seeking wide-area reach and signal stability.

The system is modular and typically mounted on a galvanized or aluminum mast, with spacing optimized for gain and pattern control.
