Although the smallest in the range, they are robust and ideal for applications where portability is of prime importance. Easily fitted to a vehicle, the masts are suited to mobile applications where light antennas are required. The top section diameter for the fitting antennas is specified in the table below.
The NH series of masts are also available without locking collars, please contact a member of the sales team for a friendly chat about 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 sq. cms. NK = 1400 sq. cms. NL = 2000 sq. cms. NX = 3000 sq. cms. NY = 11000 sq. cms.
