ANTENNAS INSTALLATION SET UP
–
Your antennas set-up is fundamental for a high performance radio transmission and
reception
✔
Connect omnidirectional antennas at the transmitter when you use several receivers placed
in different direction
✔
For short distances, you can use omnidirectional antennas with your receivers. Antenna
installation can also be easier (no need to point antennas precisely). For long distances, you
can privilege directional panel antennas at reception point. Reception sensibility is
primordial.
✔
Install your antennas :
•
1 meter minimum between each antenna of each device,
•
1 meter minimum from a wall,
•
above obstacles. (The use of mats is recommended).
For a distance of “d” kilometre, this minimum of height above obstacles is : 3,6
√
d
–
1m15 over obstacles for a distance < 100m
–
2,5m over obstacles for a distance < 500m
–
And so on
✔
“Stats” menu is very convenient to help you to install antennas : check at the receiver your
two power radio gains
REMINDER: a good set-up is when power reception valued are between -30dB et
-78dB.
