The NK Series of Pneumatic Telescopic Mast (Hilomasts) 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 head-load fittings is specified in the table below.
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 colours and finishes. Please contact us for a quote or for more information on what we can offer.
Specification for Locking Collar and Non Locking Collar (NLC) models.
|Mast||Height Extended||Height retracted||Number of Sections||Diameter of Top Section||Vertical Head Load||Max Wind Speed Unguyed||Max. Wind Speed with Top Guys||Top Guy Ref. No. inc. Stakes||Basic Weight of Mast|
The table shows the vertical headload 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.
