Mvua na dishi la Dstv kusumbua

Mvua na dishi la Dstv kusumbua

ALL 64 World Cup Games will be shown on ALL DSTV packages......
 
mkuu tatizo sio dstv jaribu kuangalia cable zako kama ziko fit and then jaribu kuwaona wataalamu pengne dish limehama position frequence kwa sababu ya upepo ama mvua!pia epuka mafundi wa mtaani vishoka,maana kuna frequence ambazo ziko strong hata upepo ama mvua vikipita dish lako haliwezi pata effect yoyote!

Ni hivi, satellite dish nyingi zinazotumia LNB za Ku-band zinakuwab na matatizo hasa kukiwa na hali ya hewa mbaya, mvua nyingi, mawingu mengi. Tofauti na LNB za C-band ambazo zipo stable sana na signal strength inakuwa vizuri tu wakati wa mvua.

So solution ni nini kubadili dish au kuomba setup za LNB C BABD
Maelezo yako ni too professional...
Naomba kusaidiwa katika hili
 
Mvua njoo....DSTV kwaheriiii

Why are Ku band signals in DTH from satellites affected more by rain than C band frequency signals?

The wave length of waves in Ku band is quite short (about 2cm). When any wave passes through the atmosphere and encounter water droplets it will cause some attenuation. This attenuation is exaggerated when the droplet ''hit'' the wave when it reaches half the wavelength in its diameter. This problem(Rain Fade) is common to all waves however, in case of waves in the Ku band, the degree of attenuation is far greater than those observed in other frequencies with greater wave lengths.

There is also some signal scattering, due to refraction and diffraction of electromagnetic waves in and around rain drops. Very heavy snow can also affect signal quality, but it is generally less likely to interfere. Satellite mini-dishes are designed to minimize the effects of adverse weather. Still, it does make sense to consider somewhat larger dish in areas where heavy rains or snow are relatively frequent, to compensate for signal attenuation.

Now for C band frequency is 4GHz and so its wavelength becomes 75mm quite larger than the size of rain drop,so signals passes through the rain with less attenuation.

For Ku band frequency is 11GHz it means its wavelength is around 25mm. It is also larger than that of rain droplet but still it has attenuation which can be managed.But if you go further i.e Ka band and V band their frequencies are very high and so very low wavelenghts.
Hence the higher the frequencies the higher the attenuation due to rain.

Hiki ndio hata mimi nilikuwa naelewa. Sasa kuna watu humu wameng'ang'ania DISH LIMEKAA VIBAYA

Dish kukaa vibaya inachangia, kuna watu wameeleza vizuri tu huku juu.
Madhara ya mvua kwa mtu aliye na signal dhaifu yanaonekana upesi kuliko kwa mwenye signal nzuri.
Well, hii inaleta mantiki, sio?

Wewe unafikiri sijui dawa ya dish kukaa vibaya? Nilichoeleza hapa ni janga kwa satellite tv.

Mara nyingi mvua ikinyesha DSTV matangazo yanakatika. Kwa mwezi huu wa nne na masika hizi si ajabu mvua ikanyesha wiki nzima au mara tano kwa wiki na hapo hutaona matangazo ya DSTV.

Je hapo si sawa na mtu unalipia huduma na huipati? Afadhali Tanesco umeme ukikatika LUKU haisomi kwahio huliwi pesa bure. Mfano leo kuanzia mchana huku nilipo mvus inanyesha mwendo ni on off kwenye DSTV.

Kuna njia yoyote DSTV mnaweza kufidia siku ambazo matangazo yanakatika kwasababu ya mvua?

Ni shida kwa kweli, weka channel za miziki ya audio tu mkuu

Niliongea kuhusu signal strength za Ku vs C band hasa kwenye mvua nikabishiwa na jamaa fulani huko juu. At least umekuja na maelezo ya kina, japo watakaoelewa mambo ya wavelength, frequency, diffraction and refraction sio wote. But at least maelezo yapo clear.
 
Nijukumu lao DSTV kuset standard za huduma zao, hayo madish madogo na hizo LNB wanatuuzia wao na wanajua fika zinaadhiriwa na mvua na huduma zao ni kwa kuhesabu siku na mteja kuona kwny, wajipange ipo siku tutawafungulia kesi mahakamani, hawa TCRA kazi yao kufungia tu blogs haki za wateja zinakiukwa wapo kimyaaa
 
Je wanaotumia lnb twin si ipo kama lnb za c-band je mvua kwa hapo bado italeta shida?
 
Kawaida inaweza kukata kwa muda.mfupi kama dakika 5 then inarudi
