The twin converter enables two subscribers (11a, 11b) to receive at least four reception ranges independently at both outputs (7a, 7b), i.e. vertical and horizontally polarized signals in upper and lower frequency band ranges. The entire broadband frequency spectrum appears at the respective polarization outputs in twin mode instead of just the lower range. The twin converter (5) enables two subscribers (11a, 11b) to receive at least four reception ranges mutually independently at both outputs (7a, 7b), i.e. vertical and horizontally polarized signals in upper and lower frequency band ranges. The converter can be expanded to form a broadband community antenna and is designed so that the entire vertical broadband frequency spectrum appears at one output in twin mode instead of just the vertical lower range and the entire horizontal spectrum at the other (9a), instead of just the horizontal lower range. In broadband community antenna system mode, the converter can be set up so that the broadband frequency spectrum for receiving the vertical polarization is present at one output, and the broadband frequency spectrum for receiving the horizontal polarization signals appears at the other output. |
