Hi, I'm Tomas with RF elements and here I will introduce the Array Sector Antenna, designed for 5 GHz unlicensed bands.

大家好，我是射頻元件公司的托馬斯，在此我將介紹專為 5 GHz 非授權頻段設計的陣列扇形天線。

A graphical installation guide, the top and the bottom part of the bracket, screws and the pole mount brackets, radio cover and the antenna itself.

圖解安裝指南、支架的頂部和底部、螺釘和杆式安裝支架、無線電罩和天線本身。

All you need to assemble and install the antenna is a single 13mm wrench.

組裝和安裝天線只需一把 13 毫米扳手。

Let's look at the RF features of the Array Sector.

讓我們來看看陣列扇區的射頻功能。

Its radiation pattern is wide in the azimuth and narrow in the elevation plane.

其輻射模式在方位面上較寬，在仰角面上較窄。

This shape of radiation pattern is good for applications where the customers are spread throughout the coverage area.

這種輻射模式適用於客戶遍佈整個覆蓋區域的應用。

Thanks to the high gain, the distant customers in the rural areas are easy to reach.

得益於高增益，農村地區的遠距離客戶很容易到達。

The landscape profile should be rather flat or mildly hilly.

景觀輪廓應為平坦或輕微的丘陵。

If you use them in hilly or mountainous regions, the elevation narrow beam will not cover the valley as well.

如果在丘陵或山區使用，高程窄光束將無法很好地覆蓋山谷。

Our Array Sector antennas are optimized for minimum side lows, especially in the azimuth plane, thanks to the backshield, our patented frequency selective surface integrated directly into the antenna body.

我們的陣列扇形天線經過優化，可將側低頻降至最低，特別是在方位面，這要歸功於背屏蔽，我們的專利頻率選擇性表面直接集成到天線本體中。

The structure of the backshield effectively mitigates the parasitic wave traveling along the PCB that would otherwise result into side lows.

背屏蔽的結構可有效減少沿印刷電路板傳播的寄生波，否則會導致側低頻。

Minimized side lows ensure you transmit and receive the signal only from desired directions protecting your network from RF noise, the number one problem of unlicensed 5GHz networks.

最小化的側低頻可確保您只從所需方向發射和接收信號，保護網絡免受射頻噪聲的影響，而射頻噪聲正是無授權 5GHz 網絡的頭號問題。

But it's not only the minimized side lows that makes Array Sector's great antennas.

不過，Array Sector 的天線之所以出色，並不僅僅是因為它能將側低頻降到最低。

Their amazing coverage performance is based on three main components.

其驚人的覆蓋性能主要基於三個組成部分。

First, the useful bandwidth of the Array Sector is really broad.

首先，陣列扇區的實用帶寬非常寬。

It covers the whole 700 MHz between the Uni-1 and Uni-3 bands, giving you enough bandwidth to optimize the channel usage depending on how crowded the spectrum is.

它覆蓋 Uni-1 和 Uni-3 波段之間的整個 700 兆赫，為您提供足夠的帶寬，可根據頻譜的擁擠程度優化信道使用。

The gain of the Array Sector is remarkably stable over the whole bandwidth, so changing the channels makes no difference to the signal level.

陣列扇區的增益在整個帶寬內非常穩定，是以改變通道對信號電平沒有影響。

Now you can truly leverage all the channels your radio supports in a reliable way.

現在，您可以真正以可靠的方式利用無線電支持的所有頻道。

Third is the stability of the main beam, showing how the gain changes in every direction.

第三是主光束的穩定性，顯示增益在各個方向上的變化情況。

It is also very stable over the whole bandwidth, adding to the overall stability of the Array Sector coverage performance.

它在整個帶寬範圍內也非常穩定，從而提高了陣列扇區覆蓋性能的整體穩定性。

The Array Sector antennas are suitable for scenarios where you need to cover a wide sector with a single antenna.

陣列扇區天線適用於需要用單根天線覆蓋較寬扇區的情況。

Thanks to the back shield, the collocation of Array Sector antennas is effortless and without limiting self-interference.

由於採用了背屏蔽，陣列扇區天線的搭配非常方便，而且不會限制自干擾。

Thanks to the industry standard radio mounting bracket, you can use Array Sector with all major radio platforms in the industry.

有了符合行業標準的無線電安裝支架，您可以將 Array Sector 與行業內所有主要無線電平臺配合使用。

Migration between radio platforms is also easy, and the plastic hood protects the radio from environmental influences, a WISP industry standard established by RF elements.

無線電平臺之間的轉換也很方便，塑膠罩可保護無線電不受環境影響，這是射頻元件制定的 WISP 行業標準。

The whole antenna is made of high-quality materials, extruded and stamped aluminum to protect the antenna from oxidizing, UV-resistant ABS plastic, and stainless steel hardware.

整個天線由優質材料製成，鋁擠壓衝壓而成，可防止天線氧化，還採用了抗紫外線的 ABS 塑膠和不鏽鋼五金件。

The Array Sector will withstand extreme environmental conditions with temperatures from minus 35 to plus 55 degrees Celsius.

Array Sector 可以承受零下 35 攝氏度到正 55 攝氏度的極端環境條件。

The durable build weighs only 3.5 kilograms and has a practical handle you can clip to a carabiner and then to a harness while climbing a tower.

它堅固耐用，僅重 3.5 千克，有一個實用的手柄，在攀登高塔時，可以將其夾在釦環上，然後再夾在安全帶上。

The bracket of the Array Sector is completely redesigned to ensure extremely easy handling, assembly, and tower mounting.

Array Sector 的支架經過了全新設計，可確保極其簡便的操作、組裝和塔架安裝。

Only four M8 screws are needed to assemble the antenna and additional four screws to attach it to the tower.

組裝天線只需四顆 M8 螺釘，另外還需四顆螺釘將其固定到塔架上。

The four screws have black-colored anti-seize surface coating, effectively protecting the screws from gelling and making the bracket very easy to use.

四顆螺絲表面有黑色防卡塗層，可有效防止螺絲膠化，使支架使用起來非常方便。

When the pole diameter is smaller than 57 millimeters, install the bracket as shown so the bolts do not protrude too much.

當電線杆直徑小於 57 毫米時，請按圖示安裝支架，以免螺栓過於突出。

If the pole diameter is larger than 57 millimeters, flip the bracket for the best results.

如果桿直徑大於 57 毫米，則翻轉支架以獲得最佳效果。

 Once you're happy with the alignment and the aiming of the antenna, you can install the radio and you're ready to go.

一旦您對天線的對齊和瞄準感到滿意，就可以安裝收音機了。
