Common interfering elements and their minimum distances from F10 Antennas are listed below:
Expansion Joints: The minimum distance from an expansion joint is 0.6 m [2 ft].
Vertical Cabling: The minimum distance from vertical cabling is 2.4 m [8 ft].
Metal Wall Studs: The minimum distance from a metal wall stud is 0.9 m [3 ft].
Sliding Doors (Metal): The minimum distance from a metal sliding door is 1.2 m [4 ft].
Tagged Merchandise: The minimum distance from tagged merchandise is 1.8 m [6 ft].
Inward and Outward Swinging Doors (Metal): The minimum distance from either a
Vertical Cabling: The minimum distance from vertical cabling is 2.4 m [8 ft].
Metal Wall Studs: The minimum distance from a metal wall stud is 0.9 m [3 ft].
Sliding Doors (Metal): The minimum distance from a metal sliding door is 1.2 m [4 ft].
Tagged Merchandise: The minimum distance from tagged merchandise is 1.8 m [6 ft].
Inward and Outward Swinging Doors (Metal): The minimum distance from either a
manual- or automatic-swinging metal door frame is 0.6 m [2 ft].
Although this last type of door is not shown in the figure, the fact that swinging metal doors can
swing toward the antenna loop must be taken into account (see below).
swing toward the antenna loop must be taken into account (see below).
Note: The antenna must not be located below the door (or too near the door) when fully opened. Locate the
F10 antenna components beyond the door – with a minimum clearance gap of 0.6m [24in].
System Performance Considerations
Nearby wiring and lighting, as well as floor construction, may affect performance. With RF
interference that is too severe and cannot be alleviated, the site may not be suitable for any
installations.

Each of the following alters F10 system performance:
• Spacing between the antenna and steel deck in the floor can affect performance, but it
has been observed that an increase in detection can occur when the F10 system is placed
on any metal flooring.
on any metal flooring.
• Floor structure may cause detection variation for the F10 system.
• Antenna configuration will cause an expected (known) change in detection heights and
• Antenna configuration will cause an expected (known) change in detection heights and
• Signal strength - The plots in the appendix have a defined height at TX = 31 (the
maximum). If TX is less than 31, detection heights will decrease.
Determining the Electronics Location
During the site survey, evaluate the store’s layout to learn what options are available for locating
the electronics enclosure and power supply. The electronics and power supply may be placed close
together, although this is not required. Both units may be placed under a cashwrap counter, under
shelving, above a drop ceiling (see special requirements), or in a utility closet.

The updated power supply can be installed in the plenum (i.e., above a drop ceiling or in HVAC
areas), but this requires a conversion kit (refer to

Note:
Since the “Hood Kit” (CKP P/N: 7367100) must be ordered separately, determine whether or not one
is needed now.
Caution: If using the conversion kit, the power supply must be installed by a licensed electrician.
