We provide measurement and calibration Tests, ODM, OEM services for certain products.
We have hundreds of customers from over 60 countries, and to meet their demands, we developed a plant in Vietnam (with a total infrastructure area of 10000 square meters, which includes three major buildings dedicated to operations and production) in addition to the main manufacturing facility in Taiwan. Now, we are focusing on automatic production lines and investing in automation equipment. In the future, we pledge to deliver the highest-quality product in the shortest possible period.
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
台股本波雖反彈千點，但季線反壓力道大，股價盤整多日，加上近3周，台股平均成交量僅在2000億元左右，市場交易情緒低落，盤整期間形成個股輪動行情，有許多投資人，想把虧損部位停損，把資金投入強勢股賺取超額報酬。
這種操作方式，在多頭行情上，也許能夠賺取更多報酬，但當全球景氣下行，強勢股有很大機率出現補跌效果，雖然台股回檔空間有限，但高點無量則難闖過季線，空頭趨勢仍然存在。
其實，換股操作的方式，跟投資心理有很大關係。快思慢想的作者康納曼曾做過一個實驗，投擲一枚硬幣，正面會得到200美元，如果擲到反面，要賠150美元。如果從概率論來看，正面反面機率各為二分之一，所以如果是精明的賭徒，一定會選擇長期下注，因為贏得收入遠遠大於輸的損失。
但是根據研究顯示，大多數人都不願意參與賭局，因為損失150美元的痛苦量，遠遠大於得到200塊的快樂，經過統計，至少要250塊才能彌補150元的損失。

另一個實驗，有50%的機率得到200萬，和100%的機率會拿到50萬，從期望值的角度，選擇前者的期望值是100萬，後者僅有50萬，但多數人都會選擇穩穩地拿到50萬，因為投資人具有強烈的損失厭惡，無法用客觀的數據衡量投資策略。
從這兩個例子，就可以了解到，損失厭惡代表著，人們面對同樣數量的收益和損失時，認為損失更加令他們難以忍受，對部分投資人來說，把那些虧損的股票賣掉，眼不見為淨，再把錢投入那些還是正報酬的股票，就是最好的選擇。
另外一部分人，也因為具有損失厭惡，不想放棄自己已虧損的股票，反而選擇賣掉獲利的股票，來抄底虧損的股票，因為他認為股票上漲是收益，一定要先落袋為安，卻沒有考慮它繼續上漲的可能性，股票下跌是損失，是不可接受的，總希望它能漲回來避免損失，如果賣掉那損失就遠不可挽回了，結果越抄越低。
這兩種損失厭惡的想法對不對？當然不對，因為買股票是要看基本面的穩固，和長期的展望，跟現在到底是被套，還是盈利沒有任何關係，如果公司已經失去競爭力，股價跌完後還會繼續疊，你只會一路抄到下市。
過去，我曾在直播問投資朋友，如果買了一支股票，當你決定要買進還是賣出，是不是取決這檔股票，未來上漲還是下跌，大家都認同。
而我又問，你買的這支股票，跟你現在是被套還是盈利有沒有關係？大多數人回答，沒有任何關係。
這就是有趣的投資心理變化，投資人都理解基本面才是長期股價的主因，買賣股票取決於基本面是否改變，但大多數人買賣股票的原因，卻是自身損益的變化。
