SMC - PA2 Sectional Mast

Radiating Masts

Our radiating masts are designed to excel in transportable, portable, or permanent use, these aluminium masts offer exceptional performance and adaptability for various applications.

With a stock range of components, SMC provides the means to convert simple tubular aluminium masts into radiating masts, ensuring seamless communication from 200kHz to 28MHz. when used with a suitable tuner.

The PA2 Series data sheets showcase a variety of masts that can be easily converted, creating a versatile range of omni-directional antennas. Choose from a wide height range of 4 to 18 meters.

For lower frequencies or situations where mast height is a consideration, we offer a capacity hat arrangement as part of the design. This addition enhances the efficiency of your operation, ensuring optimal performance even in challenging scenarios.
