5.1 Antenna Requirements
5.1.1 Standard Applicable
FCC §15.203 & 15.247(b); RSS-247, 5.4 (6)
An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible
party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a
unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section.
The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a
standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current
devices or to devices operated under the provisions of § 15.211, § 15.213, § 15.217, § 15.219, or § 15.221. Further,
this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter
protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with
§ 15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that
the proper antenna is employed so that the limits in this part are not exceeded.
If directional gain of transmitting antennas is greater than 6 dBi, the power shall be reduced by the same level in
dB comparing to gain minus 6 dBi. For the fixed point-to-point operation, the power shall be reduced by one dB for
every 3 dB that the directional gain of the antenna exceeds 6 dBi. The use of a permanently attached antenna or
of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with
the FCC rule.
5.1.2 Antenna Anti-Replacement Construction

5.1.3 Antenna Gain
The antenna peak gain of EUT is less than 6 dBi. Therefore, it is not necessary to reduce maximum peak output
power limit.
