[QUOTE="Channel Hopper, post: 62003, member: 175144"] the wdl lnb has a wr75 flange and so will only receive one polarity either horizontal or vertical, and so you would require two of them , which gets expensive and introduces the chance the lnbs will be in the way of the signal on a gregorian dish at least with the MTI it will only be a single transition between feed and lnb, however the lnb will have to be installed at 90 degrees to its usual position to clear the line of signal, and so the polarities out of it will have to be reversed at the switch I have had very good results with the AP series but as you say, phase noise and matching to the feed are very important. I think the loss through the switch after the lnb is likely to be the main problem. [/QUOTE]
