ANTENNA: SELECTION AND CONNECTION
Indoor use:
1) Use the
λ
/ 4
models, ANT119/BNC (shortened) or ANT169L/BNC (full length) with BNC male connector to be inserted
directly in the antenna output of the Radiomodem. If the Radiomodem is supported on a plan, provide a right angle adapter
BNC M / F to keep the antenna vertical.
2)
The Radiomodem can be inserted into a plastic or metal box (preferably). Provide a 13 mm hole to fix the panel TNC female
connector of an extension cable BNC / M-TNC / F and plug the BNC male on the Radiomodem antenna connector.
3)
Improved efficiency may be obtained using the vertical dipole antenna ANT169DV. This is supplied with 5 meters of low loss
coaxial cable and don’t requires the ground plane so may be installed in the most favourable mode.
Outdoor use
:
For external applications the Radiomodem need to be inserted into suitable containers for IP67 protection or better. These solutions
can be used:
1)
Close the Radiomodem in a plastic or, better, metal container. Provide a 13 mm hole to fix the panel TNC female connector of
an extension cable BNC / M-TNC / F and plug the BNC male on the Radiomodem antenna connector. Take care to assure an
efficient electric contact between the ground of the panel TNC female connector and the metallic box. If the container is of an
insulating material, the absence of the ground plane for the
λ
/4 antennas decreases the radiation efficiency. To minimise this
decreasing in efficiency a metal strip or a wide wire placed in the internal side of the box and electrically connected to the TNC
ground, simulates the ground plane and allows the utilisation of the
λ
/4
antennas ANT119/TNC (shortened) or ANT169L/TNC
(full length). For maximum efficiency in this case the vertical dipole ANT169DV is recommended.
2) The Radiomodem will be contained in a plastic or metal box with IP67 protection or better. Provide the required holes on the
bottom side of the box to fix the wall-pass cable for both antenna and supply/serial line cables. It’s possible to use the vertical
dipole antenna ANT 169DV or, in the Y3 suffix versions, the 3 elements Yagi antenna WY 155 3N to perform both the
directivity feature and a reception gain of 3 – 4 dB, keeping the maximum transmitted ERP power within 500 mW.
NOTE ON POWER SUPPLY
The Radiomodem DL169 or DL169-IN-B should be fed with a power limited voltage source between 8 and 36 Vdc and is not re-
quired a stabilisation due to the presence of an internal efficient stabiliser. The power supply is protected against polarity reversing
and is protected by a 750 mA internal SMT fuse. The current drawn depends on the power supply voltage and reaches it’s maximum
value during the transmission with the minimum supply voltage. A value of
450 mA
may be used to choose an adequate supply unit.
