What is O For that uses a Leaky Feeder System?

It is very simple to make open space radio communications and radio waves to propagate freely. However, in confined environments (underground mining, vehicular tunnels, headrace tunnel construction water, underground parking, closed buildings, etc..) Radio signals often fail to pass the walls.

On the other hand, communications are studied within confined spaces generate a lot of bouncing radio waves. As a result, communications become more difficult in these environments and the scope of communications dramatically reduced, fail more than 100 / 300 meters (depending on the frequency range used).



In confined spaces such as tunnels of rock, especially in mining, transmission of radio frequency are vital at both logistically and in the field of seguridad.Para communications solve this problem in confined spaces for more than 25 years systems have been used "Leaky Feeder", ie a continuous antenna system, where the cable passes Leaky Feeder radio signal spills in quantities sufficient to establish radio communications quality. So that the signal is of good quality and operate reliably in harsh environments, it requires the use of appropriate Leaky Feeder cable.

The signal goes through these cables to be poured as a continuous antenna, it is "spending", the linear attenuation of the signal must be countered with amplifiers spaced at regular intervals (typically every 350 meters). The quality of these amplifiers is essential to establish a reliable communications in harsh environments, such as underground mining.
