Opis
The M250 series truss mast is used primarily where architectural considerations indicate the use of a more delicate and less visible structure. Another important feature of this type of radio mast is its small impact on emissions from omnidirectional antennas not placed on the top of the structure. The radio shadow of a narrow mast is much smaller than that of a wide one. This means that we can shorten the antenna booms, obtaining a similar level of interference in the case of wider masts, or alternatively, leave the booms long, limiting the impact of the mast on wave emission (compared to wider structures).
The mast is intended for operation in wind and ice zone I, it is intended for 0.5 square meters of antenna area at the top, the height range is max 20 meters. The set includes 4-meter aluminum segments, an aluminum mast foot with two degrees of freedom for installation on the facility, lightning protection, installation screws, guy ropes with accessories (shackles, clamps, thimbles).
