Antenna Installation
• The antenna installation must provide a minimum separation distance of 20 cm from users
and nearby persons and must not be co-located or operating in conjunction with any other
antenna or transmitter.
• Antenna installation should be done by a professional installer and should meet all FCC
requirement as given in FCC part 15.
• Combined cable loss and antenna gain
• R&TTE requirements
• 900 MHz GSM band: The combined cable loss and antenna gain must not exceed
4.08 dBi
• 1800 MHz DCS band: The combined cable loss and antenna gain must not exceed
9.47 dBi
• FCC requirements
• 800 MHz cellular band: The combined cable loss and antenna gain must not exceed
2.85 dBi
• 1900 MHz PCS band: The combined cable loss and antenna gain must not exceed
2.5 dBi
OEM installers must be provided with antenna installation instruction and transmitter operating
conditions for satisfying RF exposure compliance.
Section 15.203 - Antenna Requirements
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 de-vices
operated under the provisions of Sections 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 Section 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.
