The term "universal" is used to describe an LNB that has "dual band" tuning capability. It came after the "enhanced" LNB which had a slightly extended tuning range and used a 9.75 GHz oscillator instead of 10.0 GHz. Some people mistakenly think that "universal" refers to "universal fitting", meaning the LNB will fit any dish. There is no such LNB. It's important to choose an LNB which is suitable for your dish and matches your receiver.
A Universal LNB requires a 22 kHz signal at 0.5v p-p to switch its Local Oscillator to 10.6 GHz ("high band"). Otherwise it uses its 9.75 GHz oscillator ("low band").
Dish tv lnb (ku band lnb) is Universal lnb.... hence to search dish tv signals, the lnb type has to be set to Universal type in lnb settings in the stb, in case of FTA stb's supporting cards, like solid, openbox, dreambox etc..
yes, for example : i am watching Tata sky HD on dish tv lnb
Any Ku band lnb can support any dth.... You can use commercial lnb's like lnb from sharp company etc also for any dth....
