Correct. A modded switch outputs fixed 20vdc to both ports. A C2-PLL would only receive horizontal polarization when used with the LNB mod. switch.Actually the C2PLL LNBF will not work with a switch modded to power LNBs. You have to have 13V from the vertical port and 18V+ from the horizontal for an LNBF to work.
Sorry, don't understand why you are bringing up universal LNBF? One more confusing thing added to a thread that was simply asking how to feed a dual output, voltage switching LNBF to feed multiple STBs. This thread is a big steaming mess of contradictions over nothing...True and I was wrong because that is not what the OP was asking about, no were did he mention a universal LNBF. I simply added that I use a modded switch for my C and Ku ortho feeds to give them full power.
It is incorrect to state that a modded switch that is used with your orthomode configuration (outputs 20Vdc on both LNB ports) will provide vertical and horizontal polarity reception with a LNBF like the C2-PLL. The 20Vdc output on the LNB ports of a modded switch will lock both of the C2PLL ports to horizontal polarity. Fearless Freep is correct.I have forgotten more satellite stuff than you have ever known. I am starting to assemble a 12 foot Paraclipse next weekend to use. And guess what ? It will get one of my many Titanium LNBF's on it for aligning,
