Applied Limits and Regulatory Limits: 3) FCC CFR 47 Part 15.203 6. FCC Notice: All part 15 applications will need to show how the antenna gain was derived either from a manufacturer data sheet or a measurement. Where the gain of the antenna is inherently accounted for as a result of the measurement, such as field strength measurements on a part 15.249 or 15.231 device, so the gain does not necessarily need to be verified. However, enough information regarding the construction of the antenna shall be provided. Such information maybe photographs, length of wire antenna etc. 1. Part 15 applications with equipment classes DSC, DXX, DCD, 8CC, etc. which do not have an EIRP limit. We need at least the following antenna info: Antenna photos/or drawings, including antenna dimensions. • This info cannot be held short term confidential. If necessary, we will have to request the customer to provide a separate exhibit for that antenna photo/or drawing, if the internal photos are being held short term confidential. Alternatively, antenna info can be placed in the test report. That would make things easier to review and process. (We plan on providing guidance to customers in our newsletter to identify the antenna info vs. inter…
