2. WIRING
• The transceiver unit output flange is a plain type and the antenna unit output flange
is a choke type, and it is important to maintain this relationship throughout the
waveguide run.
• After installation of the waveguide is completed, the coupling portions must be
sealed by using the adhesive supplied.
• In a very short time the surface of the waveguide becomes green with verdigris.
Therefore, paint both the surface of the waveguide and flanges to avoid corrosion
and water penetration. Paint must not be allowed to reach the inner surface of the
waveguide or the mating surface of any flange.
