Re: [amsat-bb] GOES wx sat

["Frederick M. Spinner" <fspinner@xxxxxxxxxxx>]

Linear.  The EXACT angle is determined by the "squint" of the satellite with 
respect to your position.  Best bet is to either use a linear feed with a 
method to rotate the feed/polarity (during setup) on a 2' or larger dish (4' 
works nicely) or go with a CP feed and larger dish.  A small helix for 1691 
MHz mounted slightly offset from the main feed on a TVRO setup worked like a 
charm when I still had access to the TVRO.  The polarity is different for 
each satellite along the Clarke belt.
