NX Series - Pneumatic Mast
The NX Series of telescopic Hilomast's has a base section diameter of 152mm and is pneumatically operated by air compressor. Being heavier than the NL Series it will support larger antennas and should be considered as being the maximum size necessary for general use.
Although the NX Series can be used for portable applications it is primarily designed for vehicle installation, either bracketed to the rear, or mounted through a roof bearing. Models NX18, NX25 and NX30 can be mounted onto the roof of a vehicle in a sliding carriage. The carriage slides rearwards and the mast is then tilted and clamped in the vertical position. All masts in this NX Series can be trailer mounted.
The NX30 has a top section diameter of 50mm for attaching the antenna. All other NX masts have a top spigot of 50mm diameter by 130mm long. A popular use for this range on a vehicle installation is with our HiloCAM kit.
Every mast in our NX range is available without locking collars, please contact a member of our sales team to discuss your requirements.

The table shows the vertical head load that each mast will support and the maximum operational wind speed. The weight of the antenna, however, is not usually the main criterion when selecting a mast. The limiting factor is usually the 'side surface area' of the antenna.
The wind speeds shown are based on the following side surface areas: NH Masts = 1000 cm². NK = 1400 cm². NL = 2000 cm². NX = 3000 cm². NY = 11000 cm².
