The Sectioned Mast is a heavy duty aluminium HF antenna mast available at 12 and 15 metres, rated to 144 km/h winds for supporting wire antennas at fixed base stations.
Available at 12 metres (40 ft) or 15 metres (50 ft) to suit different base station antenna heights.
Each section is 3 metres (9.8 feet) and slips into the next for easy handling and rapid assembly.
Designed to withstand wind speeds up to 144 km/h (90 mph) in clear air, subject to guying points.
Supports a head load of 12 kg (26.5 lbs) for substantial HF wire antenna arrays.
Ships with masthead gibbet, guy assemblies, guy stakes, ground base plate, gin-pole, and all hardware fittings.
Supplied masthead gibbet enables erection of a dipole antenna in an inverted V configuration.
Compact, lightweight construction makes the mast suitable for air transportation to remote sites.

Sectioned Mast raises HF wire antennas to 12 or 15 metres on heavy duty aluminium tubes engineered to withstand wind speeds up to 144 km/h in clear air. Base stations gain a modular structure whose three metre sections slip together for rapid assembly, supported by a complete kit of masthead gibbet, guy assemblies, gin-pole, ground base plate, and all hardware. Plus, a 12 kg head load and inverted V gibbet option let the structure carry Semi Delta, Terminated Folded Dipole, and Tuned Long Wire arrays at full base station height. From commercial HF sites to military base stations, the Sectioned Mast holds the antenna estate steady through the conditions that ground lighter masts.
