Pneumatic Telescopic Mast – NL Series
The NL-Series of telescopic Hilomasts has a base section diameter of 5″ and is pneumatically operated by air compressor. The shorter models in this series can be easily operated by a manual foot pump. Being heavier than the NK-Series, NL-Series masts will support larger antennas under more adverse weather conditions. Although NL-Series masts can be used for portable applications, they are primarily designed for vehicle installation, either bracketed to the rear, or mounted through a roof bearing.
Models NL16 and NL22 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. Masts NL8, NL12 and NL22 have a top section diameter of 2″ for attaching antennas. Masts NL9, NL10 and NL16 have a top spigot of 2 inch diameter x 5.1 inches long. A popular use for the NL-Series masts on a vehicle installation is with our HiloCAM kit.
The table of masts below is only a small selection of possible mast configurations. 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.
