+===Anttenna mounting===
+Installing a basic system will require the following (a) '''mounting of the antenna''' (b) optionally '''mounting 1 or 2 lightning arrestors''' (not included to product set). The antenna supplied is of the active type, and is suitable for almost all applications. It is supplied with a pre-attached, 30-meter H-155 coax cable, terminated with a male SMA connector. Before commencing installation, check that all the items detailed in the contents list have been supplied. The antenna is supplied with mounting clamps for attachment to a mounting pole, included too. Mast antenna suspension (H=0.5m) is not included but it is available as separate products from Elproma. Following figure shows an example of how mounting antenna might be achieved.

+<span style="color:red">Note:</span> The most important consideration in selecting a position for the antenna is the presence of objects which obscure the sky or horizon. Where possible, there should be no obstruction to a full view of the sky.
+Overhead wires and other very narrow obstructions may be considered as invisible to the signals, provided that they are a few meters away. Large flat surfaces can decrease performance of the receiver. Be especially wary about mounting the antenna directly onto the fascia of a flat roof. To overcome this situation, elevate the pole about 1 meter above the flat surface. A satellite prediction mobile phone program may usefully be employed to check a potential installation, and also to identify directions in which obstructions may be a particular source of problems.
+<span style="color:red">Note:</span> When the '''{{{model}}}''' is operational, the GNSS antenna assembly may be disconnected for short periods (e.g. maintenance or repair) without interruption to the unit synchronization LAN output.
+===Additional lightning protection considerations===
+As the antenna is roof mounted (to have a clear view of the sky) it is likely to be exposed to lightning strikes.
+[[File:{{{model}}}_lightning_protection.png|800px|border|class=tlt-border]]
+Protection against this is afforded by ensuring adequate grounding of the mountings as described below. There is no way to provide 100% protection for electronic equipment from direct strike damage. It is possible however, to reduce the likelihood of damage from near strike induced fields by ensuring the installation obeys some fundamental rules.
+A proprietary lightning arrestor should be installed, of a type which does not reduce GNSS signal transfer. Install the lightning arrestor near to the antenna (e.g. on the mounting pole), ensuring all connections maintain electrical and environmental protection.
+After taking the precautions described previously in the antenna installation, it should be understood that a destructive residual current may still be present in the cable coming down from the antenna to the '''{{{model}}}''' unit.
+A second lightning arrestor should be installed near to the '''{{{model}}}''' to further dissipate any remaining lightning energy. At the earth end please use multiple connection points if at all possible.
+All connections should incorporate as large an area of contact as possible, which is made more probable using large bolts, and substantial washers. Where there is no access to the metal framework of the building, it is imperative to erect a suitable lightning conductor. Failure to do so is almost certain to result in destruction of '''{{{model}}}''' and connected into it equipment in the event of the antenna receiving a near lightning strike.
