Besides, how does an LNB work?
An LNB has two important functions: it's alow-noise amplifier, meaning that it takes the extremely weaksatellite signal and amplifies it. The big, round,“dish” part of your dish acts as a lens, focusing asmuch signal as possible onto the LNB. The LNBamplifies that signal and sends it down the cable.
Furthermore, does a dirty satellite dish affect reception? But, the number of channels and size of your screenmatter little if your reception is blocked by a dirtydish. Keeping your satellite dish clean helps ensurethat you never miss that unbelievable touchdown, grand slam,full-court basket or favorite show.
Then, what angle should my LNB be at?
Best is to have a look at neighbour's installation.The LNB has to be at an angle of roughly 40 degreeswith respect to vertical - so if vertical is such that theconnector is right at the bottom, and you are looking intothe direction the dish is pointing, then turn theLNB clockwise 40 degrees.
Why does my DStv keeps losing signal?
The signal quality is a signal to noiseratio. If you are experiencing bad signal quality, it couldbe due to a faulty angle adjustment of the LNB. Bad weather willespecially influence your signal reception. The low-noiseblock downconverter (LNB) is the receiving device that is fitted onyour satellite dish.
