▲鴉片戰爭讓清軍不堪一擊。（圖／翻攝自百度百科）

清朝末年由於長期閉關鎖國，導致國力衰敗，使得強大的東方大國一直在走下坡路，逐漸淪為最末流國家，而當滿清貴族還沉浸在天朝大國的美夢中時，外國卻已經發生翻天覆地的變化，直到西方列強用槍炮打開了中國國門才有所發覺。

在鴉片戰爭開打之前，大清王朝的王公大臣甚至皇上都是抱著打打山賊蠻夷的態度來看待這場戰爭，打算給英國一個教訓，讓他們看看天朝上國的威望，可這一戰打下來，清軍竟是如此不堪一擊，於是道光皇帝在惱怒之餘也開始花心思去了解這個叫做英吉利的國家，此時台灣正好抓了幾個英軍俘虜，道光馬上就派人去提審。

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

- 天線三腳架: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

道光先是問了三個問題，第一，英吉利這個國家到底有多大，人口有多少，為何入侵我大清？第二，如果從新疆出發，是否可以到達你們國家？第三，你們國家是不是跟俄羅斯接壤？通過審問，道光知道英吉利只不過是個彈丸國家，人口更是不到大清的20分之一；於是，道光皇帝便很放心，不再提心吊膽。

這次提審最讓道光感到意外的是，英國的國王竟是女人，還是一個只有22歲的年輕女子，接著得知英國女王還是個美女後，道光立刻問了三個不太禮貌的問題，一是女王結婚了嗎？丈夫又是幹什麼的？二是一個22歲的女人，怎麼能當國王？三是女王這麼年輕漂亮，別人為何服她？這三個問題足見道光對當時英國女王的鄙視。

更離譜的是當道光知道女王只有22歲時，竟還異想天開的問周圍大臣：「女王如此年經，若將她納為我後宮嬪妃，一家人以後就不用打仗了吧？」體現出清朝當時依舊是一個盲目且自大的國家，才會提出這些荒唐可笑的問題。
