My problem is: 2 Ku band professional PLL LNBs having internal tone band switching but not internal polarity switching (they are installed on an OMT system with two separate output RF cables). Both LNBs perfectly work with 13 or 18 volt. So, adding a simple 13/18 volt switch I could use this system exactly as a common universal LNB from any receiver. When receiver sends 13 or 18 volt the switch provides to connect right LNB, when the receiver sends 22 KHz tone the connected LNB gets higher band. Any suggestion? Thank you.</p></blockquote><p></p>
