Tata Sky DTH Service in Rains

[aruneshnadar80]

Do you mean to say that ADTV does not go off in heavy rain? Hard to believe that. But logically, if dish is larger shouldn't more water get into it?

but i dont think ADTV dish are bigger than other DTH

^^^ It is bigger , Well never experience:dance::dance::dance: any blockage since installed , awaiting monsoon :dance::dance:

1. It is not necessary to have falling rain; even water particles present in the atmosphere and the travel path of the sat signal can absorb the signal resulting in loss of tv.2. All geographic areas do not receive the same signal strength; the foot print is like a contour map. In fact, for bigtv, northern areas receive a high level signal than the south.3. When the signal strength falls below a certain level, the stb may treat it as no signal to avoid showing a poor quality picture or snow. The cut off level may be different for different providers; like the laptop shutting down when battery remaining drops below 10% or 3% as the case may be. If the service provider offers a bigger dish, it may be because the footprint is weak!

i want know that if in uploading area its raining what will happen:huh::huh:

Uplinking will be with a narrow focussed high strength beam; signal attenuation may not be significant.

the signal goes off even in dark clouds :huh:

i dont think uploading is done on Ku band..so rain in the uploading area should not affect the broadcastIts the KU band used for downlink that is susceptible to attenuation and signal degradation..even the normal analogue cable that we get at home also comes from the satellite only but its not affected by rain coz the Band is different ie the frequency/wavelength are different and radio waves with different frequencies behave differently when travelling thru the atmosphere.

great explanations in this page, don't know whom to quote :rofl:
