Flexible waveguide (FR-9)

The RF interconnection between the Antenna Unit and the transceiver can be made with a flexible waveguide (FR-9). If the rectangular waveguide is used, observe the following installation guidelines.

• Correctly installed waveguide runs ensure the most efficient transmission of electrical energy at high frequencies. Electrical losses, however, occur in the waveguide runs. To minimize them the following factors are of great importance: minimum length, airtightness and electrical continuity.
• Another consideration required is that of frequency disturbance. The transmitting valve, a magnetron, is the primary oscillator in the radar. This is different from the oscillation system at lower frequencies in which conventional radio valves are used. In the latter case, the primary oscillator is always protected from the effects of load impedance by a buffer stage so that frequency and waveform are left unobstructed. With a waveguide and magnetron, however, mismatch of impedance causes “frequency pulling.” For this reason, the number of possible mismatches in a waveguide run, i.e., joins and bends, must be kept minimum.
• Each pair of flanges should be coupled with one O-ring, four bolts and spring washers and the choke flange must be in the upper position. The bolts and O-ring must be greased before insertion to facilitate removal if required at a later date.
• 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.
