G.2 Assembly and installation of the antenna
Different mounting structures for antennas are shown below. From the left-hand side, we have an L-
shaped wall-mount, a three-leg mount and a standard straight mount. The tube diameter is 76 mm. For a
correct mounting the surface must be vertical or horizontal, respectively.
Non-penetrating roof-mounting structures (requiring no screws or bolts) may also be used if the customer
do not want to penetrate the roof. The foot can be rectangular, “H-shaped” or have another suitable form.
It must be loaded with at least 75 kg depending on the antenna size and maximum wind force.
Install the antenna and adjust pointing and polarisation as described in the manufacturer’s installation
instruction [2][3][4][5]. After connecting the cables from the IDU to the transceiver (or BUC/LNB/OMT)
and completing the installation of the antenna with feed horn and transceiver (or BUC/LNB/OMT)
proceed with fine adjustment of antenna pointing and polarisation assisted by the IDU as described in
section 6.3.
Finally, the F-connectors must be protected against rain and humidity. Use a self-vulcanising tape suitable
for out-door use. The cables must also be properly marked and should be strapped to the antenna feed
mount.
