13cm Septum Feed

The next goal was becoming operational on 13cm. Material has been collected, transverter has been build, now working on the pwr amp and the new feedhorn. Of course we wanted to carry on with the round septum. This is how it looks. The mesurements of the feed are in the Septum feed measurement section

Raw material, pipe has been rolled from a plain sheet of 1,5 mm copper
