My present feed cone is a Chaparrel serial cb 1317627, volts 15 to 22. With this cone there is a polarization box that the wires need to come back to the General Instrument 450i then return to the vonwise actuator. My thoughts are to make the 450i the dish mover only and not hook up the polarizer. Going this direction, I would use the Mercury 11 for all other needs and would put in a different feed conewhich is a C and KU band lnbf.The new cone is a Geo Sat Pro CK1 which is the standard LNBF. I can remove the entire Chaparral cone and put in and have two separate feeds. A C feed and a KU feed. Then I would have to put in a switch since they would feed into the same line. Do you see any problem in changing to this type of a set up? The reason for changing is because I did not understand the wiring diagram so I did not put in the extra wires. The 450i has the automatic C/Ku change over which I will not be using with the new setup. The actuator is hardwired from the 450i. I would appreciate some feedback. My real question is do I need the polarization box with the mercury and using the vonweise actuator for the 10 foot dish?
