烏克蘭跳高女神奪金淚灑：保護國家了

In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.

A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing

烏克蘭人民頑強抵抗俄羅斯侵略，讓全世界佩服，而不只國內的人民在奮戰，有烏克蘭仙級「跳高女神」之稱的女將雅羅斯拉娃.馬古奇赫(Yaroslava Mahuchikh)，也在經歷3個星期，躲防空洞的日子後，成功參加世界田徑錦標賽，並以2.02公尺的超強成績奪下金牌，讓她披著國旗繞場一圈時忍不住淚灑「我在運動場上保護國家了。」

在烏克蘭聶伯城出生的雅羅斯拉娃，是田徑界著名天才跳高女神，個人最佳成績，室外2.04公尺、室內2.06公尺。2018年參加夏季青年奧運拿下金牌，同年又成為U18級別的世界及歐洲冠軍，2019年參加世界田徑錦標賽時，雖然拿到銀牌，也刷新世界青年紀錄。2021年參加東京奧運，拿到銅牌，絕美顏值和身材，成了田徑場上關注焦點。

2月24日，烏俄戰爭爆發，雅羅斯拉娃也像其他烏克蘭民眾一樣，得離開住處躲進防空洞裡。

Double Ridged Horn Antenna
Sort by:Select
The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.

The advantages of Horn antenna:

- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.

- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.

- Easy to make, simple design.

The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.

Recommended Accessories

- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

綜合外媒報導，雅羅斯拉娃花了約3天時間，穿越戰火，抵達塞爾維亞參加世界田徑錦標賽。而在眾人歡呼聲中，跳出2.02公尺好成績，奪下金牌。

在拿到金牌、披上國旗瞬間，全場報以熱烈掌聲，讓雅羅斯拉娃淚灑。賽後告訴媒體，她經歷了3天的艱辛車程，比賽時，心情相當複雜，因為她無時無刻都還掛念著烏克蘭，她也為自己的表現相當滿意，因為「我在運動場上保護了我的國家。」

不過被問到接下來怎麼辦？雅羅斯拉娃強調，她知道現在要回家很難，現在她也必須到德國，但她想趕快回家，因為她的父親、朋友都還在烏克蘭，她非常擔心。

除了雅羅斯拉娃，根據烏克蘭最高議會回報，跳遠女將瑪麗娜.貝.羅曼丘克(Marina Beh Romanchuk)在三級跳遠項目，也以14.74公尺的好成績，拿下銀牌。
