DD Free Dish is a free-to-air direct-to-home (DTH) service in India. To receive signals from DD Free Dish, you need to have a satellite dish antenna and a Low Noise Block Downconverter (LNB) installed on it. The type of LNB you need to install depends on your dish size and location.
For a standard 60cm dish, you can use a Universal LNB (U-LNB) that supports both vertical and horizontal polarizations. However, if you have a larger dish or are located in a remote area, you may need to use a higher-gain Ku-Band Universal LNB.
Ku-Band Universal LNB -
Ku-band LNB is a type of Low Noise Block Downconverter (LNB) that is commonly used in satellite communication systems. The Ku-band frequency range is between 10.7 GHz to 12.75 GHz, and it is used for various applications such as direct-to-home (DTH) television.
The Ku-band LNB is mounted on the DD Freedish DTH dish antenna and receives the signals transmitted by the satellite in the Ku-band frequency range. The LNB downconverts the received signals to a lower frequency range (usually in the L-band frequency range), which can be easily transmitted through the coaxial cable to the satellite receiver. For Universal LNB, you should use 09750 to 10600 LNB Frequency. - Know How to Change DD Free Dish LNB Frequency
Ku-band LNBs come in different configurations, including single, dual, and quad outputs, which allow users to connect multiple set-top boxes for multiple TV connections. Some advanced Ku-band LNBs also have built-in features such as noise reduction, amplification, and polarization adjustment to improve signal quality and reduce interference.
