 Insat-4B carries the following payloads:

12 Ku- band 36 MHz and 27 MHz usable bandwidth Transponders (9 and 3 numbers respectively) employing 140 W TWTAs to provide an EIRP of 52 dBW over the footprint covering Indian main land.

2 C-band 36 MHz bandwidth transponders employing 63 W TWTA to provide an EIRP 39 dBW with expanded coverage encompassing Indian geographical boundary, area beyond India in southeast and northwest regions.

Kalanithi Maran's Sun Group has booked seven Ku-band transponders on Insat-4B for its soon-to-launch DTH service Sun Direct, while Prasar Bharati's free-to-air (FTA) package DD Direct Plus has booked five.

Sun will be using MPEG-4 technology that will allow it to compress more TV channels per transponder. While MPEG-2 can pack in around 12 channels, the advanced compression technology will be able to accommodate over 20 channels.

Sun may consider itself lucky that the launch of Insat-4C satellite failed in July 2006 after the rocket carrying it
