- FIG. 5 is a sectional view along the line V-V of Figure 3
- FIG. 1 shows a parabolic antenna 1 equipped with a low noise source arrangement 2 according to the present invention
- This arrangement is designed to allow the reception of signals with linear, horizontal or 3 vertical, transmitted by two geostationary satellites from a relatively short distance from each other
- Each satellite can transmit on two frequency bands, a low band ranging from 10.7 GHz to 11.7 GHz and a high band going from 1 1, 7 GHz to 12.75 GHz
- the converter arrangement converts the total band from 1 1, 7 to 12.75 GHz in a band from 0.950 to 2, 150 GHz
- the signals thus converted are transmitted to a receiver 3
- the latter can therefore receive signals transmitted by satellite A1 (not shown), with linear horizontal or vertical polarization, situated either in the low band or in the high band and signals from the second satellite A2 (not shown).
- the arrangement comprises two low noise converters 5 and 6, commonly called in the LNB technique (Low Black Block) each comprising a waveguide 7 and 8 respectively.
- waves 7 and 8 comprises an input waveguide element 9 forming a source and an output waveguide element 10
- the elements 10 are fixedly mounted on a support housing 12 which houses the electronic device mounted on a plate printed circuit 13 It is the output 14 of this plate which is connected by a coaxial cable 15 to the receiver 3
- Each input waveguide element 9 is axially aligned with the output element 10 and is angularly mounted thereon.
- the element 10 carries at its front end a flange 17 and the end rear of element 9 is provided with a flange 1 8
- the two elements are assembled by connecting the two flanges 17, 18 using screws 19
- the screw opening 19 is made in the flange 18 in the form of an arcuate oblong hole 20
- Each input waveguide element 9 is provided with means for converting signals with linear vertical or horizontal polarization into circular polarization signals in either direction of rotation.
- These converting means are formed by a Teflon strip 22 which extends inside the element 9 in the longitudinal direction thereof
- the blade 22 is fixed diagonally in the element 9 by engaging by its longitudinal edges in grooves 23 in the internal face of the element 9
- the ends of the Teflon blade 22 are configured in dovetail
- the two output waveguide elements 10 also house a Teflon blade indicated at 25 which has substantially the same shape as the blade 22 and is mounted in the same way but angularly offset by 90 °
- This blade 25 constitutes a means for converting signals with circular polarization produced by the wave element 9 into signals with linear linear polarization wedge or horizontal
- At the rear end of the output waveguide element 1 0 are provided, as can be seen more clearly in FIG.
- two antenna elements 27, 28 produced in the form of points projecting radially towards the inside of the internal face of the element 10, while being angularly offset by 90 °
- the element 27 extends horizontally and is used for receiving signals with horizontal polarization while the element 28 is oriented vertically to reception of vertically polarized signals

- the signal plane of the satellite A1 or A2 coincides with the orientation of the antenna elements 27, 28 of the converter 5 or 6
- the adjustment is made by rotation according to the appropriate angle of the element input waveguide 9 of each converter
- the angular position of the support box 12 is also adjusted according to the different elevations of the two antennas, by rotation of the arrangement around an axis parallel to the input parts 9
- each program is identified by the satellite A1 or A2 which transmits it, by the type of polarization which is vertical or horizontal. and by the low or high frequency band that the program occupies
- the receiver 3 switches the polarization switch 32 of the appropriate converter to the type of polarization of the program signals. This switching is effected by sending the appropriate polarization selection signal SP, namely d '' a continuous signal of 12 volts if the polarization is vertical or of a signal of 18 volts if the polarization is horizontal Then, after a predetermined delay the receiver selects the satellite A1, A2 This selection is made by sending or not sending of a certain number of successive bursts of oscillations, constituting the signal 6
