This unusual subscriber`s equipment is a grave SHF antenna that is supposed to be used first of all for ensuring high reliability of the communication channel in all-weather conditions. The blasts of the wind, snow, ice, impudent ravens attacks - all these factors can hardly damage the all-welded array of aluminum profile of the 25mm cross section. The antenna feed is reliably protected by the plastic radio transparent case. The antenna mounting implies the change in polarization, and in 120-cm "plate" - also the adjusting of the beam taking into account the mast tilt and the direction to the object.
Because of the fact that the antenna is made as an array, its windage is significantly lower than in the case of classical all-metal reflectors. Naturally the cost of these antennas if relatively high comparing with the mass products. However, if compared with the prices of the worldwide leader RFS for the similar production, our price seems to be very attractive.
