蔣友柏短袖不怕冷 兒照樣復刻
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.

[周刊王CTWANT] 蔣家第四代、橙果設計創辦人蔣友柏現身時總是招牌光頭加上背心，相當顯眼。不管天氣多冷，他經常也只穿短袖加背心，靠一身肌肉來保暖；西洋情人節前一日（2月13日）就有讀者看到招牌穿搭的他，果真不論氣溫多低，他又是短袖、短褲搭了迷彩背心，格外引人注目，他和前妻、女星林姮怡生的一兒一女出現在捷運中山站，兒子蔣得勇除了和爸爸長得像，穿搭也完全復刻老爸。
在大家都穿著外套包緊緊時，一對父子穿著短袖、短褲，很難不注意到他們，蔣友柏一身肌肉超禦寒，相比之下，兒子露出的手腳就略顯消瘦，走在兩人中間的女兒蔣得曦（小玫瑰）一頭金髮，呈現如布丁頭一般的漸層，一家三口步伐極快，快速爬上手扶梯，看起來很趕時間，三人幾乎沒有聊天對話。
蔣友柏工作忙碌，不只和友人、北歐盃烘焙大賽冠軍陳志煌在台北信義區百貨公司開設快閃咖啡店，也在跨年時在內湖舉辦個展，但他經常被媒體捕捉到與兒女外出，先前本刊也曾披露他帶兒女去買手搖飲，工作之餘不忘和孩子們培養感情。

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
