LNB (Low Noise Block converter) is the signal receiving point on your dish antenna. To receive the clear and stronger satellite signals the LNB should be pointing towards the satellite without any obstacles like trees or buildings in the line of sight. Here is the guide to learn about LNB adjustments.

Initial requirements before you begin to adjust your LNB:

1. Before we begin to adjust the LNB of our satellite dish, we should have the awareness regarding the type of satellite to which the LNB is positioned. There are two types of LNBs.
   • LNB pointing towards stationary satellites - All the DBS satellites are geostationary which travel around with the earth in the same speed, thus appears to be at one place as a stationary satellite.
   • LNB pointing towards moving satellites – The moving satellites frequently change its position in the earth’s orbital space.
   • A LNB Tester is a must to perform LNB adjustment on any type of LNBs. LNB tester locates the available signal and the signal’s strength either in digital format or analog format.

How to adjust stationary LNB:
We do not need to frequently adjust LNB pointing towards a stationary satellite. It will be a onetime adjustment done during the initial installation. However incase of strong wind or any natural calamity there are chances that the LNB could de-position itself and provide bad signals or no signals for the TV reception. To perform the adjustments to re position the LNB, we need to place the LNB tester between the receiver (LNB) and the dish. LNB tester detects the available signal and the current signal strength. Reposition the LNB towards the direction LNB tester gains the maximum signal strength. Most of the DBS satellite receivers require to point towards the south sky with no obstacles in the line of sight.

How to adjust LNB pointing at moving satellite:
But in case of the moving satellite, we may need to tune to the current frequency very often. In olden days we need to manually tune the antenna, perform trial and error methods to obtain strong signals. But with the technology advancement, today’s satellite dishes had come up with a rotator installed on it. A remote control has also been provided to help the user to set the directions for the LNB to reposition itself without performing manual tuning. Using the remote control we can set the azimuth, skew and elevation of the satellite. The rotator on the dish rotates and points the LNB towards the direction we had keyed in using the remote control. Thus repositioning could be achieved for LNB connecting to moving satellites.
