DD Free Dish DTH Service

India's only Free Direct-To-Home Service primarily known as DD Direct+

Transponder Frequency conversion of DD Free Dish and Dish TV as per LNB Frequency

Some of the members of DD Free Dish have very old satellite receiver set-top boxes. The limitation in those STB’s is that the Frequency input (that is LNB Frequency, Transponder Frequency) is only upto 4 digits like say 5150MHz for LNB Frequency is fixed. Thus the user thinks that it is only a C-band satellite receiver and cannot receive Ku-band channels.

But that is not true. A satellite receiver STB can receive C-band as well as Ku-band (unless particular band restriction is specified). Its the LNB chosen for that band reception that makes it possible. That means a DD Free Dish DTH receiver STB can also get C-band channels in MPEG-2, DVB-S if its connected to a aligned bigger dish with C-band LNB.

OK lets say your old STB has this 4 digit frequency input only. So here we see how to calculate and convert the 5 digit frequencies to go well with the receiver and ensure good Ku-band channels reception.

Consider WOW Cinema on DD Free Dish DTH. The Parameters are Transponder Frequency: 10990MHz, Symbol Rate: 28500Ksps, Polarization: Vertical, Video PID: 514, Audio PID: 614.

As a rule of Ku-band, if Transponder Frequency is less than 11700MHz, then LNB Frequency will have to be kept 9750MHz and 22K Tone=OFF, and if its greater than 11700MHz, then LNB Frequency will have to be kept 10600MHz and 22K Tone=ON.

So now when you see a Ku-band transponder on DD Free Dish, Dish TV etc, you should be able to know what to keep LNB Frequency.

Lets come back to the 4 digits world.

Then we keep/have LNB Frequency 5150MHz and Transponder Frequency for WOW Cinema will be 5150 + 9750 – 10990 = 3910MHz

Rest all Symbol Rate, Polarization, Video PID, Audio PID etc will remain the same.

The Parameters are Transponder Frequency: 12688MHz, Symbol Rate:27500Ksps, Polarization: Vertical, Video PID: 4531, Audio PID: 6116.

zee_punjabi_haryana_himachal_ddfreedishWe keep/have LNB Frequency 5150MHz and Transponder Frequency for ZEE PUNJAB HARYANA HIMACHAL will be 5150 + 10600 – 12688 = 3062MHz

Rest all Symbol Rate, Polarization, Video PID, Audio PID etc will remain the same.
