IRFU 2+0 with single remote mount antenna
Requires a length of elliptical waveguide dependant on the distance between the antenna
and the IRFU (Figure 66). Requires waveguide dehydration accessories. The receiver
coupling is internal to the IRFU. The IRFU may be purchased with equal or unequal
coupling, the unequal coupling option provides a better link budget (nominally 6 dB) for
the Primary transceivers.
