These tones and voltages are sent up the coaxial cable from the back of the receiver to the output of the LNB. The quad LNB provides four outputs, each capable of providing each of the four frequency bands and polarizations. The LNB outputs are switched by the s atellite receiver , as explained above, with a 22Hz tone and a switching voltage. This is like a universal LNB with four outputs. A quad LNB is ideal where a maximum of four satellite feeds is required and there is not much possibility of expansion.
Quattro LNB. A quattro LNB is normally used to feed a large distribution system. A quattro is normally used to feed a large distribution system.
A single dish with a quattro fitted and a multiswitch is able to feed anything between 4 and locations. The outputs on a multiswitch are able to be controlled with a 22KHz tone and switching voltages in the same way that the outputs from normal universal LNB can be, i.
The satellite receivers in each of the locations behave as though they are connected to their own dedicated dish and LNB, but in reality are just connected to a multiswitch output. Quattros are considered to have a better lifetime than quads as they are not being continually switched. Note again the difference between a quad and a quattro LNB: A quad LNB can drive four tuners directly, with each output providing signals from the entire Ku band.
A quattro LNB is for connection to a multiswitch in a shared dish distribution system and each output provides only a quarter of the Ku band signals.
I suddenly experience difficulties with my DStv explora. Hennie: please put a call through to your local professional satellite installer to help you re-align your dish to refocus on the DStv position. I have just installed a dstv Explora Ultra. Can I get YouTube as an app? It is currently not available under my apps option. How do i install it?
A million thanks Lemmy for the DIY. I only needed a ladder and a spanner to remove the old LNB install my smart LNB, adjusted to receive signal, followed your step-by-step instructions, quick setup. Thanks again sir. How do I link old explora decoder to a zappa with just one rf input the explora is working fine now I wired it with a dual lnb and a diy switch so now I want to connect to a zappa which I connected it to the a port on the diy switch only channel comes up but other channels come with the no link with the primary decoder error.
Now my question I do I need a dixpler fo it to work?? I tried tracking startimes Using Digital dual mode decoder. Kindly advice. Hi Lemmy, I think I had the cable on the wrong port on the smart wuad lnb. It should be on the Unicable port on lnb and will check , thank you. Good day, I had to move Explora to another building, connected dish but shows no signal on tv. Tested level on lnb with Rover sat pointer and it is 77db and at input to explora it is 66db.
Can anyone give advice please. Good day Lemmy. Then, after loading, some old movie is missing. What could b the problem. I did not av such issue when I was using explora 1. You may need to reset your decoder to fix the issue you are experiencing.
Hi lemmu, can my explora use SNLB? Pls how do i remedy this? Please book an appointment with your satellite installer. Am presently using zappa HD decoder. I just got explora 2. From what I have learnt from your discussion, I can do the installation on my own. Just to change the lnb to the smart lnb that came with the explora. Pls confirm that to me.
I also want to continue using the zappa in other room with its subscription not extra view how do I go with it without installing another dish. Please I just need the diagram. Thnk u. Hi Lemmy, just curious.
I would assume that making Explora 3 primary would be best. I also use RF out for my 3rd TV to catch both decoders channels. My friend bught dstv explora decoder. Is it neccesarry to cange settings from univesall lnb to smart lnb? Or any advise you can give me plz. Please create a youtube channel. Hi i am struggling to connect 2 explora decoders on one satellite dish LMX support 2 decoders from same lnb without affecting one another we have tried with twin LNB we failed please please help.
Please use a sat finder to first track it or call a professional satellite installer.
