Highly Versatile

PT Series

PT Series masts are medium duty telescopic pneumatic masts for use as communications masts, cctv masts, antenna masts, radio antenna masts, microwave antenna masts, radar masts, camera masts and more. Many models are availble with an internal electrical or video cable. 

Made from aircraft grade seamless drawn 3.25mm wall aluminium tube with a 4.5" base tube diameter and a maximum of 7 sections, the PT Series are one of the most versatile masts in the range. Telescoping mast sections are anodised and a full length keyway is machined to prevent rotation. PT Series masts are available in rotatable and non rotatable versions. Plain collars and locking collars are available depending on the requirement. If the mast is to be left unattended for long periods then locking collars are recommended.

Various top fittings are available including 25mm & 40mm top sockets, round flange or square flange (with glanded cable entry points)


Accessories can be painted to match the mast.

Nycoil Assembly

A Nycoil cable assembly can be used in conjunction with a spreader bar fitted to the mast head to guide, protect and manage cables for video cameras, antenna or other equipment fitted to the mast. Cables which are unable to be internally fitted such as coaxial can be routed externally in a strong, flexible protective nylon nycoil tube. When retracted the nycoil assembly sits coiled on the vehicle roof extending when the mast is operated.
