VOLUME III, CHAPTER 2, ODU INSTALLATION
The mount can also be used to remotely support a protected ODU pairing installed
on a coupler. The coupler connects to the remote mount assembly in the same way
as an ODU.
The remote mount clamps to a standard 112mm (4”) pole-mount, and is common to
all frequency bands. The figure below shows an ODU installed on a remote mount.
Two versions of the remote mount are available, a cast unit (as shown) and a stain-
less steel unit.

Flexible waveguides are frequency band specific and are normally available in two
lengths, 600mm (2ft) or 900 mm (3ft). Both flange ends are identical, and are
grooved for a half-thickness gasket, which is supplied with the waveguide, along
with flange mounting bolts.
To prevent wind-flex, a flexible waveguide or coax must be suitably fastened or sup-
ported over its length. Where it is not possible to fasten directly to the support struc-
ture, hanger assemblies are recommended, comprising a stainless steel clamp,
threaded rod and a form-fit rubber grommet. The figure below shows a typical
assembly.

Flexible waveguide and hanger kit options are available.
