The NK Series of pneumatic telescopic masts (Hilomast) have a base section diameter of 102mm and are pneumatically operated with either a manual footpump or small air compressor.
The NK series is equally suited to both short and medium/long-term deployment. The top section diameter for headload fittings is specified in the table below.
The table below only shows 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 colours and finishes. Please contact us for a quote or for more information on what we can offer.

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 sq. cm. NK = 1400 sq. cm. NL = 2000 sq. cm. NX = 3000 sq. cm. NY = 11000 sq. cm.
All dimensions are approximate.
