Whilst they may only be a couple of degrees off, this difference can cause issues with reception, moreso when one is looking at low symbol rate signals where there is a similar frequency on the opposite polarity, and upset by the cross pol rejection characteristics of the LNB design.Sometimes the use of a four port LNB where the two local oscillators are running all the time will create more issues when receiving low signal transmissions, one reason why commercial installations still require highly stable DRO and narrow bandwidth LNBs for successful reception.</blockquote>
