ECLIPSE INSTALLATION MANUAL
The flexible waveguides have tin-pl ated brass flanges to mi n-
imize di ssimilar-metal corrosion between the aluminum feed-
head on the ODU and the brass antenna port(s) used on most
standard antennas.
Where a fl exible-waveguide length greater than the 900 mm
(3 ft) maxi mum included in the Eclipse Accessori es list is
needed, contact the Aviat Networ ks Help Desk.
Remote-Mount Installation Procedure
This topic describes the installation of a remote mount, the attachment of the ODU
to the mount, and the installation of the flexible waveguide.
Related procedures are:
l Grounding an ODU; refer to Grounding the ODU on page 56
l Installing the ODU cable and connectors; refer to Installing ODU Cables and
Connectors on page 58.
Installing the Remote Mount
The remote mount attaches to a standard 112 mm (4”) pipe mount using two saddle
clamps. It can be installed either way up, and with a left or a right offset.
Firmly fasten the clamp nuts.
Attaching the ODU and Flexible Waveguide
Before attaching the ODU to the remote mount, fit the flexible waveguide to the
ODU.
1. Remove one gasket from the packet supplied with the flexible waveguide, apply a
thin smear of silicon grease to the gasket, and fit the gasket to the recess in the
flange.
2. Firmly attach the flex waveguide flange to the ODU feed head using the bolts sup-
plied.
3. Screw each ODU mounting bolt in approximately six turns, then thread the wave-
guide through the center of the mount and attach the ODU to the mount.
o
Insert the bolts through receptor holes in the mount, then rotate the ODU
clockwise to bring the mounting bolts hard up against the slot ends.
4. Firmly tighten the four bolts with an open-ended 19mm (3/4”) spanner. Torque
to 18-22 Nm.
5. Prepare the antenna-end of the flexible waveguide as in step 1 above.
6. Check, and adjust if necessary, the run of the waveguide for best protection and
support position before fastening the flange to the antenna port.
