Question : How to install another LNB on Same Ku Band Dish?
By : Mr. Abdul Hakim Khan
Answer: Hello, you mean you want to install multiple LNBs on same small ku band dish antenna. It is very easy here are some easy steps:
Dish size should be 60cm to 100 cm for good gain, because one small dish gives 40-60 db gain so use your dish antenna branded and good quality.
Best prefer antenna is ” Dish TV’ because it is cover Horizontal space widely.
Selection of LNB, always choose low noise figure lnb for best signals, if you are using low size dish antenna.
Best prefer LNB is “Solid 0.01 Noise Figure (75db Gain)” or Ultra Black but it is very costly.
I always suggest mpeg-2 / dvb-s receiver at the time of installation, because mpeg-2 receiver can lock channels in low gain and show you real time gain info bar. So always use mpeg-2 receiver at the time of installation, try to on Tone burst from your set-top box if available, because this is easy way to set your dish.
always use good cable and connectors, because if you do not use good cable it can take more gain, for example if you are receiving gain from Dish 50db gain and your cable is taking 10db gain then your set-top box receive only 40db gain, it means it will not lock channels, and you will see low gain.
How to point your dish on correct satellite?
While installation dish, you should remember that there should be gape of 1-6 degree within satellites, because under 4-5 degree you can catch satellites easily.
DD Direct Plus Satellite ( Insat 4B) Available at 93.5 Degree
Dish TV (Nss6) Available at 95.0 Degree
(Both satellites you can catch by Single LNB because there is difference only 1.5 Degree)
Dish TV (Asia sat) Available at 100.5 Degree
On single dish, Single LNB will not able to catch three satellites, now you will have to set another lnb, check given below pictures for more information
