Alternative for Monoblock LNB if you cannot get it.

Many members are either not able to get monoblock lnb or do not wish to buy it due to some reasons.

So we can easily combine two single Ku-band lnbs with a DiSEqC switch and use it to get beams from satellites separated by an angle. Incase of DishTruHD monoblock lnb, the angle is fixed at 4.3 degrees. But this one is flexible in terms of separation angle and look angle.

Cost of this contraption = Rs240 (2 Ku-band LNBs)+Rs150 (4-in-1 DiSEqC switch) = Rs390.
Cost of monoblock LNB varies from Rs400 to Rs650.

For now only LNB pics as I am fitting this on my dish antenna. Later I will post the performance of this with TV screen images and signal details.

TruHD has dual tracking LNBC...atleast mine does...@aboveThe signal that is transmitted from the station is of high power as its transmitted in the open space..they have to keep the power high....or else noise will play witn our signal...but while we recieve the signal...the high power signal cannot be transmitted as it is...because of such high power...or the cables required should be of uber quality..which might get costly...so to decrease the cost of cables...a small thing is installed in the dish...which decreases the signal power keeping the SNR as intact as possible...but nothing in the world is precise...it does pass some noise with our original signal to our STB....OR sometimes it cannot dcecrease the signal power to extent we want..hence end up with distortions or unwanted inf..or no signal at all..Normally HD users..whether its dish,reliance,airtel....suposed to have 2 SUPRESSED LNBC's to track HD and SD content both differently....But apparently they do scam i guess..but technically its not possible...

Sorry.. this might be stupid question but what is its use?

Your question is very good dear,
LNB is used to receive the signals reflected from a dish antenna. This Dual LNB will help receive 2 or more satellites at a time as the case happens with Dishtv transmitting both SD and HD channels on 2 satellites located nearby.

Let me know if you have any further questions :)

Dear Shatrughan, The pic you have shown is of a Dual Output LNB used to run 2 different set-top boxes on 1 LNB.

My purpose is getting 2 different satellites from a single dish on a single set-top box.

This pic will make it clear. 2 Satellites are received now NSS6 and another Asiasat5 without moving or re-aligning dish.

Yes Mham07 Sir, this type of LNB can be fit on any old dish. It main use is for receiving more than 1 satellite signals in a range of 4.3 degrees and you can use it as per your need. You can get it in Coimbatore, Madurai etc. Cost of this monoblock LNB is a bit high Rs650. But you can get a single Ku-band LNB for around Rs120.Dishtv staff will come and fix it if you request them. If you have the skills, you can do it yourself ;) Let me know if you need to know more about this :)Have a great day ! Take Care.
