The WB68 can be used with a 3LNB dish or the newer 5LNB dish, both with four output lines. It cannot be used with the old dual LNB round dish with only one or two output lines.
On second thought, I believe you're right. The 22kHz ports should only be needed for addressing the 110/119 sats, so it should work with a dual LNB dish also.evan_s said:I would expect it to work just fine in an SD system with the 13v and 18v no tone ports hooked up.
Their FAQ seems to agree
