注意！針對美國所有Part 15部分的有意發(fā)射設備-天線增益信息，點擊查看！

日期： 2022-08-29

以下是來自FCC部門負責人的緊急信息!

?針對所有Part 15 部分的有意發(fā)射設備，需要隨附天線的data sheet 或者test report，目前FCC不知會用何種方式調查EAS system中已完成申請的認證資料，但如果接收到FCC通知需要補上天線資料的FCC ID，必須在5個工作日之內補上，否則FCC ID將會被撤消，但何時會通知，要追朔多久以前的ID，目前都沒有相關資訊。

? 針對已發(fā)證的ID，F(xiàn)CC可能會進行抽查，如果被抽到可以聯(lián)系信測并提供相應的天線資料補交或信測測試后補交。

針對未發(fā)證的ID，請及時準備相應的天線資料或聯(lián)系信測測試。

必要的天線訊息如下：

1. 天線的類型 (如Dipole, Panel, etc.)；

2. 天線的頻率范圍與對應的最大Peak Gain值；

3. 天線的照片 (可同產(chǎn)品照做短期保密，如果有保密的需要)，天線的尺寸，天線的cable長度與天線接頭也需要拍攝清楚；

4. 天線Data Sheet中，有相關敏感訊息(如設計原理，參數(shù)，等等)，可以刪除分開提供并要求保密，其他必須要公開；

5. 如果提供的是天線報告，則須符合ISO 17025的報告內容要求，如: 測試方法，測試儀器清單，測試示意圖，測試照，測試數(shù)據(jù)等等，報告無法保密，但其中測試照做短期保密。

原文如下：

URGENT - FCC Area of

Concern-Antenna Gain Information

The following urgent information has been provided by the FCC:

Any applications granted without the proper antenna information will be dismissed after 5 business days of this email. The TCBs can request to have the application put in an audit status to update the antenna information.

This email is to bring to your attention that while the FCC has been advising test labs and TCBs to make sure part 15 applications includes antenna gain information, in terms of data sheets and/or test reports. This information is evident by recent audits confirming this information was omitted.

We are still finding reports that state, "antenna gain information is declared by the manufacturer", with no other supporting information. As we have re-iterated during the last TCB workshop, this statement will not suffice. 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, example such as a field strength measurement on a part 15.249 or 15.231 device. As a result, 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.

The antenna gain information shall be made public. Any proprietary information such as construction maybe stripped from the gain information report and held confidential. The main antenna information we require is the maximum gain of the antenna for the band of operation. This information must be provided as a data sheet or a measurement report.
