Examples
Other complex higher borides LnB 50 (Tb, Dy, Ho Er Tm Lu) and LnB 25 are known (Gd, Tb, Dy, Ho, Er) and these contain boron icosahedra in the boron framework.
The "higher" borides (LnB x where x > 12) are insulators/semiconductors whereas the lower borides are typically conducting.
The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter (LNB).
This is called the low-noise blockconverter (LNB), and the unit consisting of the horn plus the converter is called the LNB with feedhorn (LNBF).
