Satellite - Wind Force at the Parabolica

►Introducción

* When choosing the location where a satellite dish is installed, it is always advisable to consider possible frequent exposure to strong winds, as it can loosen its precise targeting, especially in reception boundary conditions (secondary multifocus antenna LNB, very diameters adjusted to the power of a satellite positions with various co-positioned satellites, etc.).

* For this reason, will require restraint systems and suitable fixing suffer if wind gusts, both to avoid pointing deviations, resulting in signal loss as the discomfort to access and properly readjust the antenna.

* In this sense, it is highly recommended also ruled antennas most basic budget ranges and invest just over budget on an antenna with fittings and supports higher quality, because in extreme cases temporary in coastal areas can get to establish the difference between a slight mismatch of antenna or discards it and definitely lost.

►Tablas guidance

General theoretical values ​​below on the force exerted by the wind in Kg given different speeds and antenna diameters are provided.

These values ​​are reduced by about 40% if it is of reflector antennas perforated mesh, depending on their density, it being possible also to compensate the force exerted with high pointings (elevation) of the antenna to reduce wind resistance.

The above calculations would be valid as long as the antenna is fixed to the ground or using a wall mount, as if holding in a tower in height or in gaps between buildings with effect hallway wind (stronger gusts) should consider other how it affects factors that add complexity to the formulas.
