Part # US/FCC CANADA/IC
WLM400 KQL-WISMP 2268C-WISMP
Antenna List
The WLM400 has been designed to operate with the antenna listed below and having a maximum gain
of 2.5dbi. The required antenna impedance is 50 ohms.
Item Part Number Mfg. Type Gain (dBi)
1 S181FL-6-PX-2450S Nearson Dipole 2.5
2 S151FL-6-PX-2450S Nearson Dipole 5
 The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as
an antenna appearing in the table and still maintain compliance. Laird Technologies offers
several different options for dipole antennas. Contact your Laird sales representative for more
information.
ANTENNA REQUIREMENT
To reduce potential radio interference to other users, the antenna type and gain should be chosen so
that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful
communication.
FCC/ IC MODULAR APPROVAL
The WLM400 has been granted an FCC / IC modular approval. Further RF testing by the OEM is not
needed to comply with FCC / IC standards for inentional radiators pursuant to FCC Part 15 Subpart C and
RSS-210.
The WLM400 has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 Subpart B of the FCC Rules. The OEM is responsible for verifying that their equipment complies
with the unintentional radiator limits set forth in Subpart B once the WLM400 has been integrated into their
product.
