Stagger Tuning
Stagger tuning of the Antennas should be
used to prevent crosstalk between zones if
Controllers/doors are less than 50’-70' apart
(depending on building structure) on the same
floor, or floor-to-floor. Change the frequency
of the Controllers to prevent them from
interfering with one another.
However, if Controllers/doors are within 10’
on the same floor, and/or their Tx fields are
overlapping, keep them on the same frequency
to prevent the Controllers from competing to
activate and read the Tag. (Figure 2.4).
See chapter 8 for information on how to
configure the antenna’s dip switches to the
different channels/frequencies. Each Low
Frequency Tuning switch on an antenna must
be set to the same channel/frequency.
See chapter 7 for information on how to set
the channel/frequency in the software to
match the frequency set on the board.

If distance between
LC1400Ts/doors is less than
50’-70‘ (depending on building
structure) on the same or
different floors, change the
frequency.
If distance between
LC1400Ts/doors is less than 10’
on the same floor and their TX
fields are overlapping, keep to
the same frequency.
