ATIM_ARM-Dxxxx_UG_EN_V1.11
Figure 1: Connecting the antenna.
The use of coaxial cable type RG58 (-1dB / m) is not recommended (high loss)
2.1 Antenna
A bad choice of antenna can have considerable consequences on the quality of the radio link. It is important to
use a suitable antenna and, if necessary, a low loss cable to place it in a slightly obstructed area.
Table 1 shows the antennas available to order:
ANT868-14S-L
1/4 "roof antenna with 3m80 cable + SMAM plug

ATIM_ARM-Dxxxx_UG_EN_V1.11
2.1.1 Mounting on a cabinet
A.R.M. radio modems can be supplied with a ½ wave whip antenna angled so that the antenna is positioned
vertically directly on the modem.
This antenna is interesting if A.R.M. is mounted in a plastic box. In this case the antenna must not be placed
against a metal plate (bottom plate for example). ½ Wave antennas do not require a ground plane and can
therefore be mounted directly on a non-metallic surface.
If the radio modem is mounted in a cabinet or metal cabinet, you can use the antenna ANT868-14S, antenna
¼ roof wave with its cable and SMA plug.
The antenna should be mounted vertically (up or down, depending on the area to be watered). For optimal
results, it is advisable to place it high and clear of any metallic obstacle in a radius of 1 meter if possible (see
figure 2).
Figure 2: Placement du modem.
2.1.2 Outside mounting of the antenna (on mast)
In this case, you can use the antenna referenced ANT868-BZ with a cable type CFP10 (low loss
diameter 10mm). With this type of cable, you can deport the antenna 10 or 20m or more depending
on the link budget (we can calculate it for you to know the distance between the two or more
points, the type of antenna and the desired cable length). Do not use any coaxial cable or RG58
which, at this frequency, causes a colossal loss. See Table 1 previously.
There is in radio what one calls "the area of Fresnel" which makes an ellipse between the 2
antennas (see figure 3). The more we wish to transmit far, the more it will mount antennas (~ 1m /
km, a height of 5m for 5kms), this to avoid any obstacle in this area. In free field and at sight, with
antennas installed according to these recommendations, the range of A.R.M radio modems can go
up to several km.

2.1.3 Spectrum
Before installation, check if possible which radio frequencies are used nearby.
2.1.4 Distance of transmission
The ARM / 868-D version extends the range to more than 10kms.
2.1.5 Radio channel selection
The selection of the radio channel is done either by the USB configurator or by the encoder wheel.
It is possible to use the other radio channels of the radio module other than those of the coding wheel. To do this
you have to deactivate the checkbox of the configurator (Coding Wheel channel enable).
The encoder wheel has 16 positions from 0 to F (hexadecimal). Position 0 is used for updating the software.
There are 2 corresponding tables for one at frequencies compatible with the old range and for the other at 15
frequencies compatible with the new range ARM-N8. This selection is made using the checkbox "Compatibility
ARM".
The configuration of the modem must comply with the standard and therefore, the parameterization must
respect a transmission time (duty cycle). The power is not the same depending on the chosen channel, see
below:
