The mobile phone jammer company welcomes people from all walks of lifefor inspecting

so the design must take into account the local topography and climate in the 10GHZ band rain attenuation below the rain and fog dissipation does not seem particularly serious, for a hop band the following rain and fog may 10GHZ loss does not seem particularly serious, the following bands , will introduce several decibels.The mobile phone jammer company welcomes people from all walks of life for inspecting. will introduce several decibels in 10GHZ above band repeater spacing limited mainly by the loss of rainfall, such as 13GHZ to 10GHZ above the main band repeater spacing limited by the loss of rainfall, such as 13GHZ to more than band, the band, 100mm / hour rainfall will cause 5dB/km loss, so 13GHZ, hours of rain will cause the loss of so 5dB/km 13GHZ, the loss, the band, 100mm / hour rainfall will cause 15GHZ band, generally the maximum distance about 10km relay 15GHZ band, generally the largest relay in the 10km distance around around frequency band in 20GHZ above
