Realization:

Through purchase of 2 pieces Astra low-installations too ever DM 198, - came we to two Sat. Receivern and two 60 cm Offset parabolic-mirror. Two singles LNBs was enclosed as well that was not usable for our purposes however. In contrast to a Sat. Installation, where is only received, must also be sent with a Interlink. That means that that must be brought send with a parabolic-antenna also as the reception-signal into a focus. As solution, a polarization-points became (English orthogonal fashion transducer, OMT) with Feedhorn in the focus fortifies. With former satellites reception-installations became transmitted polarizations the two of the satellite with it (hor. + vert.) separated and at ever a rectangle-hollow-leader (TypR 120 as well as WR 75) led out. There, then separate LNCses became for them/her/it horizontally and vertically empfangenen programs connected. For our purposes, we have a LNC rebuilt for 10 GHzes at a hollow-leader-exit and screwed on the Sendebaustein at the other. That means that takes place program and reception with different polarization. On the other side, LNC and stations must be installed on the reverse connections of course then, otherwise one lacks 30 dB levels approximately..... (hi). The OMTses could be acquired favorably with a wholesale dealer as remaining stock.
