Listen IR Expansion Link RJ-45 Connections
The coverage area of the LT-84 can be extended by adding up to four (4) LA-141 Expansion Radiators.
A maximum of two (2) LA-141s can be connected to each Expansion Link output RJ-45 on the LT-84 with a
maximum daisy chained CAT-5e cable length of 100 ft. (30.5 m).
CAT-5e cable must be at least 24 AWG!
Refer to the diagram below.

appropriate frequency row then move over to
the overall cable distance from the LT-84 to the
LA-141 being set, this is the switch setting.
