Crestron CWD6671 Two-Way RF Transceiver Module
Antenna Requirements:
The module must be installed such that the antenna connector is accessible for direct
antenna connection in the final configuration. If any cable or antenna other than that
provided with the CWD6671 is used, then the FCC authorization is no longer
considered valid and the FCC ID cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for reevaluating the end
product (including the transmitter) and obtaining a separate FCC authorization.
Section 7.1.4 of RSS-GEN
This device has been designed to operate with the antenna(s) listed below, and
having a maximum gain of 2.5 dBi. Antennas not included in this list or having a
gain greater than 2.5 dBi are strictly prohibited for use with this device. The
required antenna impedance is 50 ohms.

Frequency 2.4-2.5 GHz
Type Dipole
Polarization Linear
Impedance 50 Ohm
Gain 2.0 +/- 0.5 dBi

Section 7.1.5 of RSS-GEN
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
More than that permitted for successful communication
