An integrated dual-directional feed horn, for receiving RF signals from two satellites in small angle, includes a LNBF (first low noise block with integrated feed) and a second LNBF. The antenna dish focus the received RF signals onto receipt points of the focus plane, and the two LNBFs receive focused RF signals. The first LNBF receives circular polarized waves from the BSS satellite. The second LNBF receives linear polarized waves from the FSS satellite. One characteristic of the invention relies on integrating two LNBFs and making the two LNBFs adjacent to each other in the direction of short axis. Accordingly, the two LNBFs receive RF signals from two satellites in small angle. Increasing the length of the long axis thereof increases the areas of the wave-guides. The signal gain and communication quality are obtained.
