Deciding the Antenna Installation Position
10. Direction of waves emitted from the antennas
11. Other points about magnet-base antennas
The OMRON V690 microwave RF-ID system uses frequencies within the
range used by the wireless unit and so if they are used on the same floor,
observe the following points when installing.
• Separate the antennas and ID tags by at least 3m.
• Set frequencies outside the range 12CH to 30CH.
Antennas emit waves in certain directions, and there are certain directions
in which waves are received easily. These directions are known as the “di-
rectional characteristics.” The directional characteristics for pencil anten-
nas and magnet-base antennas when they are installed vertically are
donut-shaped, spreading outwards horizontally. Radio waves are emitted
in every horizontal direction but are not emitted upwards or downwards.
• The magnet on the magnet-base antenna is very strong. Do not remove
• Twist the cable as little as possible.
• Before mounting the antenna to the wireless unit, check that the plug
• Design the hole for passing the cable through so that the cable is pro-
the antenna by pulling on the cover or cable. Doing so may damage the
antenna. Be sure to hold the base when handling the antenna.
and jack are properly connected and then tighten them by twisting the
ring nut. When mounting, twist only the ring nut; do not twist the cable.
