Does anybody know why they are different and which is the main signal carrier coming from a dual LNB. I had to replace my multiswitch and forgot to label each cable (long run from dish to multiswitch).
The different voltages select different polarizations of the satellite signal. This allows each LNB of a dual LNB to receive a different set of channels. If you have the standard round dish with one dual LNB, it does not matter which LNB gets which voltage, as long as each gets a different voltage.
If your multiswitch has 22khz inputs, connect them to a second LNB. which is for sat B on an elliptical dish.
