What are the differences between DRO and PLL lnbs?

DRO (dielectric resonator oscillator) LNB types have very poor frequency stability and are suitable only for the reception of wide bandwidth carriers, such as a 27 Msps satellite TV or VSAT outline carrier, where the receiver tuning circuits can lock onto the carrier despite frequency errors of up to +/-500 kHz or +/- 2 MHz and second's delay (or more) locking up is of no consequence.

PLL (phase lock loop) LNBs use an internal 10 MHz crystal oscillator (which has high stability) and a phase-locked oscillator at say 10 GHz.  Frequency accuracy is very good (say +/-25 kHz) and phase noise is low.  Use this type for the reception of low symbol rate carriers and higher order modulation carriers like 8PSK and 16QAM.  External reference PLL LNBs are also available. These need a 10 MHz supply up the cable from the indoor equipment.  External reference PLL LNB accuracy can be extremely good if you use an atomic-derived oscillator such as one based on a GPS receiver.  All teleport hub earth stations should use external reference PLL LNBs. The 10 MHz supply should have excellent phase noise characteristic so make sure its power supply is well smoothed and it is not located next to a motor (e.g. a fan which give out both vibration and an oscillating magnetic field).    

You can Receive TV Signals from Ku-Band like DD Free Dish and suitable with other DTH like Tata Sky, Dish TV, D2H, Sun Direct, Zing Digital, and Airtel DTH. It is also capable to receive other Ku-Band FTA channels from different-2 satellites.
