IRFU 1+1 Tx MHSB with single remote mount antenna
Requires a length of elliptical waveguide dependant on the distance between the antenna
and the IRFU (Figure 57). Requires waveguide dehydration accessories. The receiver
coupling is internal to the IRFU.
Choose IRFUs with equal or unequal coupling. The unequal coupling option provides a
better link budget (nominally 6 dB) for the Primary transceivers.
