Re: DSS Dishes



I'm using an 18 inch Sony DSS dish with fairly good results.  I replaced the
LNB with a helix feed and Millicom downconverter.  This morning (2/27) I had
the MB S9 above my S1 noise floor during the early part of the transponder
period.  If you are going to use a smaller dish work on putting the lowest
NF preamp or downconverter we can up as the first stage.  My next project is
to get the NF down from about 3db to <1 db.
