Antenna 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.
Mounting GNSS antenna
Note! 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.
Note! When the NTS-pico 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.
