(2) Cutler feed. Another useful rear feed is the cutler feed shown
in Figure 162. This consists of a resonant cavity, which is tuned by means
of the adjusting screw, with two radiating slots which feed energy to the
reflector. The radiating elements of any of the rear feeds may be enclosed
in an airtight box for the purpose of pressurizing the waveguide of coaxial
line.
