1.  Mount antenna pigtails and Ethernet insulators in their respective holes. Seal the unused 
holes with the provided rubber seals H
2.  Install the spacers J on the baseplate C using screws K, as in the picture. Spacers should 
be placed on top of the baseplate in the positions desired (depends on the type of Router-
BOARD you will use) and fastened with screws from underneath.
3.  Place the baseplate inside the case box, minding the orientation of the baseplate. Note 
that if you have installed the baseplate correctly, a hole in the case will match a respective 
hole in the baseplate – this hole is for the grounding screw.  Install the grounding screw G 
in this hole. It is supposed to go all the way through the case, where the jagged washer 
and Wingnut should connect the grounding. 
4.  Attach the baseplate to the box with the K screws at it’s top and bottom. 
5.  Attach the mounting rail with the selfscrews to the bottom of the box, screw the rail to the 
pre-made screw holes - this is to maintain a distance between  through three washers 
the box and the rail, to allow space for mounting rings (see image). 
6.  Place the RouterBOARD device on the baseplate and secure it with the K 
screws to the previously installed spacers. Insert the ethernet cable into 
the device port, and attach the pigtail to the wireless card.
7.  Insert the rubber isolation cord E into the shaft near the edge of the case 
cover B, and trace the cord all the way around the cover. The cord is sup-
posed to be longer than needed – you will need to cut it so that both ends 
are slightly overlapping. The cord should match the ridge near the edge of 
the base A. Close the case and secure the cover with the screws F.
8.  Use the rings D to fasten the case on the mast. Mind the orientation: it 
must be mounted with connectors down, as there are two small ventilation 
holes, which must be pointed down to avoid water leaking inside the case. 
Make sure to tighten the rings reliably to prevent the device shift/rotate in 
high wind.
