NSTALLATION
The units are designed to be mounted via 6-32 size screws which must be supplied by the end user.
There are a number of 6-32 UNC threaded holes on each face of the main housing to facilitate mounting
in many different applications and in any orientation; please refer to Appendix A for exact mounting hole
locations. The preferred mounting scheme is to fix the ATOM to the larger assembly using at least four
mounting points on each of two opposite sides of the unit. Other arrangements are possible depending on
the requirements of the application; please contact Norsat technical support for details. Please leave at
least 1 inch of clearance around the fan air intakes.
The unit is entirely watertight and suitable for outdoor operation. All joints are O-ring sealed. The
waveguide port J4 is not internally sealed, so the antenna feed must be sealed with a radome or window,
and all waveguide joints should be O-ring sealed if water-tightness is required.
