We recently launched the HA-02M03G01-NF, which is considered an upgrade version of HA-02M03G-NF with attributing to the persistent research of FT-RF CEO - Mr. Chen and RD team. This becomes one of the largest designs in the line of Double Ridged Antennas, despite the fact that the product weighs only 15kg. 

This product's specifications are listed below. With a frequency range of 200 MHz to 3 GHz, it was tested at 3 different distances: 1M, 3M, and 10M.

「我聽到有人在討論股票時會提到內盤、外盤，究竟這是什麼意思呢？」

表１、內盤與外盤對照表

上下五檔報價

解釋什麼是內盤、外盤之前，我們先要知道股票的上下五檔報價，這是「未成交」的委託價與數量，意思是：離成交價最接近的五個買方價位及賣方價位，如果你的委託單符合對方的委託價與數量，就可以立刻成交。內盤指的就是「成交」在委買的價格，而外盤指的是「成交」在委賣的價格，請見下圖１：

圖１、長榮上下五檔與內外盤

依據圖１，股票代碼２６０３的長榮當時委買價１３４.５元，委賣價１３５元（圖片右下角粉紅色框框處），兩種狀況說明如後。

狀況１：如果這時候你立刻要買到１張，最低應該用多少價格委託呢？１３４.５元？這無法立刻成交，因為有６９１張排在你前面，你要委託１３５元才可以立刻成交，那邊有１,２５６張委託賣出的對手可以馬上賣給你。你用１３５元的價格立刻買到１張，這筆成交量就算是「外盤」成交。

狀況２：如果你這時候立刻要賣掉１張，最高可以用多少價格委託呢？用１３５元？這無法立刻成交，因為有１,２５６張排在你前面等著賣出，你要委託１３４.５元才可以立刻成交，那邊有６９１張委託買進的對手可以馬上跟你買。你用１３４.５元的價格賣出１張可以立刻成交，這筆成交就算是「內盤」成交。

由此可知，外盤成交顯示的是買方比較積極，願意出高價搶購。而內盤成交顯示的是賣方比較積極，願意降價求售。統計內盤與外盤的成交量占比多寡，可以觀察股價的相對變化。

舉例１：內盤成交多 股價跌

依據圖１，長榮當時的內盤成交占總成交量６０.８３％，外盤占３９.１７％（圖中粉紅色箭頭處），內盤成交多，股價跌幅１.１０％。這代表的是有約６０％的成交量是賣方降價求售，賣方相對積極，股價也剛好呈現下跌走勢。

接下來我們看另一個例子，請見下圖２：

圖２、聯發科上下五檔與內外盤

舉例２：外盤成交多 股價漲

依據圖２，股票代碼２４５４的聯發科當時的內盤成交占總成交量４５.５％，外盤占５４.５％（圖中粉紅色箭頭處），外盤成交多，股價漲幅０.８４％。這代表的是有約５５％的成交量是買方高價搶購，買方比較積極，股價也正好上漲。

小結

１.內盤指的是成交在委買的價格，顯示賣方比較積極，願意降價求售，內盤占比高的股票下跌機會相對大。

２.外盤指的是成交在委賣的價格，顯示買方比較積極，願意高價搶購，外盤占比高的股票上漲機會相對大。

３.影響股價的因素很多，沒有任何單一指標能夠解釋所有股價變化，投資人還是要多方參考各種資訊，自行判斷。

聲明：投資一定有風險，以上純粹舉例說明，不代表推薦個股，亦不保證獲利。

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
