Pneumatic Telescopic Mast – NX Series
The NX Series of telescopic Hilomast masts has a base section diameter of 5.9″ and is pneumatically operated by air compressor. Being heavier than the NL Series, the NX Series will support larger antennas, etc., when extended. The NX Series masts should be considered as 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 2″ for attaching an antenna, etc. All other NX Series masts have a top spigot of 2″ diameter x 5.1″ length.
Hilomast, LLC also offers custom-built applications with all of the masts in all of our series.
Please feel free to contact Hilomast from our “Contact” page of this website, or call Hilomast, (386) 668-6784, and we will be glad to discuss details and/or options on the NX Series or on other competitive products in which we specialize.
Note: The table of masts below is only a small selection of possible mast configurations available to you. Due to the modular design of all Hilomast pneumatic masts, we are able to offer masts in custom sizes, with or without locking collars, and in various colors and finishes.

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 = 1 ft². NK = 1.5 ft². NL = 2.1 ft². NX = 3.2 ft². NY = 11.8 ft².
