[QUOTE="Rick, post: 745466, member: 317022"] Accross the pond there is alot of circular polarised KU band. Because the signal is reflected a second time it reverses the LH and RH polarisation. A reversed LNB just compensates for this. You could just as easially swap the polarisation over in your transponder settings to make the adjustment. It dosen't put the signal out of phase, all that happens is that the reciever would be looking for a LH polarisation, but because of the double reflection would see a right hand polarisation. And even then you might need a KU Band Linear Polarised LNB if you want to recieve channels broadcast on linear polarisation, which a reversed LNB is incapable of recieving. Here in Europe circular polarised KU band isn't used, and the extra reflection has no effect on a linear polarised signal. Any standard universal LNB will do. Unless you have a need to alter what rooms recieve what I would fit the switches outside, and Cable in to feed points. [/QUOTE]
