The 505 and single tick mark must remain directly away from the feed support arm, at all times.

I need to know is with this lnb, is the normal configuration to set the assembly to horizontal polarization then rotate the the dish 90 degrees to obtain nominal vertical polarization. and if this is so which way do i rotate from the back of the dish to set vert nominal. if my final polarization will +43.3
 With the feed arm at the bottom and the Universal LNB with its connector sticking out sideways. This is true Horizontal receive polarisation. Go behind the dish and turn the polarisation anticlockwise by 90 deg till the feed arm is on the right hand side. You are now true Vertical receive polarisation. Now adjust the polarisation by an amount of +43.3 deg clockwise, back down. All viewed from behind the dish facing forwards towards the satellite in the sky. Count the amount of +43.3 deg along the scale. Ignore the numbers if they go backwards from 90 or whatever. It is the amount and direction of adjustment that matters. I am assuming that the +43.3 is correct and came from https://www.satsig.net/maps/lat-long-finder.htm Some minor final adjustment of polarisation may be necessary, possibly to about +46.8 deg clockwise. You are allowed to make up to +/-5 deg adjustment at the feed yokes, that is what the 505 means. wxw Best regards, Eric.
