The Scala HDCA-5 is a ruggedly built yagi antenna, designed for professional FM transmit and receive applications. Like all Scala antennas, the HDCA-5 is made of the finest materials using state of the art electrical and mechanical designs resulting in superior performance and long service life.
The HDCA-5 may be used stand alone or in stacked arrays for higher gain, increased side-lobe suppression, or custom azimuth patterns.
