Murag ok ni sya bro, but make sure you adjust this correctly the angle to get the best signal. and adjust as well your cantenna that serves as your lnb, coz it may not work if not properly adjusted. The same adjustment with the real lnb i think. If your familiar with dish adjustment, then it wont be a problem. Im sure everyone could do it. Of course at first is a learning process, but im sure everyone could do it.
Im using dish for quite a while, i dont see any problem if you have the guts, its quite easy actually.
Seems like, the Cantenna on the pics is not properly been installed. It seems too far from the dish, this may have a problem. It seems too far from focus of the dish as well, so this may have a low signal as well. Im sure, it doesnt need a very long can, the trick here is the focus of the dish to get a better signal.
