I have been searching unsuccessfully for a DBS feedhorn to use on a prime focus dish.
This is to be used with a single polarity LNB covering only the DBS-11.7 to 12.2ghz band.
They do exist in offset versions but cannot be used because of the different f/d ratio.
My quest is motivated by the belief that it would yield a better performance with such LNB than my wideband feedhorn.
Any ideas? Thanks.
