Waveguide Style – The REMEC connector type is available for both rectangular and circular
waveguides. Be sure that the antenna's waveguide style matches the ODU. For details, please
contact Solectek technical support at support@solectek.com.
An example of antennas compatible with the SkyWay-LM ODU is shown in Figure 5-1 below where both
rectangular and circular waveguide types are shown. The units in your possession may have either
circular or rectangular, depending on the ODUs that you purchased. Solectek supports rectangular
waveguide types for most frequency bands, except for 7, 8, 38 GHz. The waveguide structures of both
types of ODUs are shown in Figure 5-2.
During assembly, it is critical to pay attention to the antenna's polarization.
Use the following steps to mount the ODU on the antenna:
Lay the antenna on a flat surface.
Apply the supplied lubricant around the cylindrical wall of the antenna waveguide structure.
NOT put the lubricant inside of the waveguide.
Remove the plastic end cap on the ODU waveguide.
Slowly lower the ODU on the antenna waveguide, aligning the latches on the ODU and the
antenna (Figure 5-3). When the ODU is lowered all the way, use the two alignment pins on top of
the antenna waveguide to firmly fix the ODU in the right position.
DO NOT press down hard on the ODU – Physical damage may occur to the waveguide structure
(Figure 5-4).
Fasten the four latches on all four corners (Figure 5-5). Make sure that the latches are pulled all
the way up to the vertical position (Figure 5-6)
Two of the four latches have a locking feature (Figure 5-7). They can be used to protect the ODU
from tampering or accidental loosening of the latches. You can put either a tie-wrap to secure the
latch or a pad lock for better protection.

2 ft antenna) – Note the latch parts on four corners and vertical/horizontal polarization markings.
