the unit is supported using at least eight of the mounting holes on two opposing sides (four holes per side).
The waveguide output port (J4) must not be used to physically support the unit.
Refer to Appendix A for the size and position of the ATOM mounting holes.
3.1.2 Outdoor Use
The ATOM is designed for use in an outdoor environment and is sealed to prevent water ingress. Ensure
the waveguide and/or feed connected to J4 are also sealed with gaskets to prevent water ingress.
3.2 Fans & Baseplate Cooling
The standard ATOM configuration employs an integrated radiator and IP55 fans to cool the unit. A minimum
clearance of 1 inch must be maintained around the air intake and exhaust during use. The fans are a field
replaceable assembly; contact Norsat for details on replacement kits. If the unit is deployed inside a
radome, ensure there is adequate cooling to remove heat and prevent the unit from overheating.
The ATOM is also available with a flat plate in place of the radiators and fans. It is the user’s r
esponsibility
to ensure that the plate the unit is mounted to is capable of rejecting any heat produced by the unit. Please
contact Norsat for cooling requirement specifications.
3.3 Accessories
Each ATOM unit ships with mating connectors for the both M&C Port and the Power Port connectors as
well as hardware for the waveguide flange and ground terminal. No hardware is provided to mount the unit.
A range of optional accessories such as pre-built power cables, M&C test cables, and M&C signal adaptors
are also available; please contact Norsat for details.
