1.2. Mechanical interfaces

This chapter describes basic properties of each RAy unit, which are important for its mechanical install-
ation: antenna waveguide, unit fixing (screws, etc.) and unit grounding (screw + cable). Other interfaces
(for data, power and service purposes) are described in next chapters Ethernet + power interfaces and
Service interfaces.
1.2.1. Antenna waveguide
Antenna waveguide flange on RAy unit (located across the holder) ensures perfect microwave connection
between the unit and the antenna. All RAy units are equipped with identicaly sized round flange (with
the outer diameter 50 mm and the inner diameter 28 mm). The only visible mechanical difference
between RAy models are the diameters of the round waveguide hole in the middle of the flange. Those
diameters differs according frequency ranges and are following:
10-11 GHz
17-18 GHz
24 GHz
70-80 GHz
RAy3 link requires use of external parabolic antenna for each RAy unit – both for physical mounting
as well as for the wireless transmission itself. Parabolic antennas

Important
Each antenna has to be equipped by a corresponding RACOM RAy antenna waveguide inter-
face - the metallic pivot (28 mm diameter) with a rubber O-ring on it, otherwise the signal
to/from the unit can not be transmitted from/to the antenna and such a link would not work.
