SMC Radiating Mast
MF/HF Tubular Aluminium Antenna
SMC carry a stock range of components which enables a simple tubular steel or tubular aluminium mast to be converted to a radiating mast for the 200kHz to 28MHz MF and HF bands. (Spot frequency or tunable with appropriate antenna matching unit).
Any of the masts described in our data sheets PA2 or TS series may be converted making a very versatile range of omni directional antennas from 6-30 metres in height, in 2”, 3” or 3½” diameters. For the lower frequencies (or where mast height is a consideration) a capacity hat arrangement may be included in the design for more efficient operation.
The SMC PA2 series of portable aluminium masts are particularly suited to transportable, portable or permanent use with the appropriate fittings, and the TS series masts are normally for permanent Installation.
The price quoted on this product page is for a typical low power AM antenna system (without antenna tuning unit which is available separately) with 60ft (18.29m) radiating alloy mast complete with erection kit, top capacity hat guy wires with insulator separators, T stake anchors, turned base insulator and portable radial earth system.
We can design and build you any AM radiating mast antenna to match your requirements.
