Before migration most of our customers were using a single line LNB and a splitter to share the signal between two receivers. The two receivers were working well and customer where able to view different channels from different transponders as they were all transmitted horizontally. The effects of the satellite migration
The table below contains the current transmission details. Frequency Number Horizontal 12341 Horizontal 12379 Vertical 11938 Vertical 11976 Vertical 11785
Transponder Number 4973 4975 4952 4954 4244
Voltage 18v 18v 13v 13v 13v
Based on the above table, installation is going to work in the following manner.
Single Line LNB o
The LNB will work on a customer who is connecting to one TV point, no second decoder. Customer can use the same connection to share with the signal with a second TV point. (This means the 2 TV’s will use one decoder and watch one channel.)
o
A single-line LNB can only serve one receiver at a time, and you can only view one channel at a time on one transponder. You cannot use a multi-switch with a single-line LNB to split the signal.
Dual LNB o
Dual LNB connections operate independently of each other, so you can use two receivers. A dual LNB can access different channels on different transponders; you can install a multi-switch to split the signal to more receivers.
Multiswitch
Multi Switch A multi is recommended when installing more than one STB to a duel LNB.
o
Installing a multi-switch on a dual LNB allows for multiple receivers to view different signals. According to smarthome.com, "The satellite receiver will send either 13V DC or 18V DC to the LNB and it will tune into either odd or even transponders. You can't split a signal because one receiver may need odd and the other may need even. If you need more than two outputs, you use a multi-switch. One input of a switch sends a constant 13V while the other sends a constant 18V. If a receiver needs odd transponders the switch will connect that output to the correct input."
