Depends on the yacht - angle varies see assembly instructions for Windex 15 here;

windexdevelopment.com/assembly-instructions/

An old comment on YBW includes;

Windex. Settings for the arms, as advised on carton:
60 deg - normal ocean racers. 55 deg - boats with extremely good windward performance. 65 deg for auxiliaries etc.

They are only there to give you a reference. A lot of people set them 30deg off bow because most boats sail to windward at about 30 deg to apparent wind. I personally set it to about 30deg off the stern as it gives you a quick reference as to if you are sailing by the lee.

Thanks for the helpful replies. But I'm not sure I understand Jodes reply. I thought it was of the Center line. Wouldn't the bow or stern be the same? Anyways as it is only a guide I will set mine at 30 each side. I haven't climbed the mast as yet but one side has shifted to about 40 and the other is about 20. Birds I guess. Thanks again

Believe you are talking about the same thing. It is usual to set the 2 arms off the stern centre line as they are therefore easier to see from the cockpit helm position. The wind arrow itself is pivoted in the centre of it so when sailing upwind it will show the apparent wind about 30deg off the bow centreline and the rear of the arrow will be over one of the arms. When sailing downwind the forward half of the arrow will be pointing aft. We have our arms pointing aft and the wind indicator is invaluable running downwind for both symmetrical and asymmetrical spinnakers. So as to show when the apparent wind moves aft of abeam usually indicating a kite can be set, and not running too low with asymm kites which is slow, or by the lee with any kite which is slow and also dangerous as regards chinese gybes.

r13, 100% agree, that's what I was trying to say. You put it better than me.
