針對空大招生疑慮，空大副校長沈中元指出，這次委託張姓博士招生，是台中中心正式召開「招生會議」，而且事後上簽報備，經校長批准的；搞成這樣他很遺憾，至於是否與校長選舉有關，他說：「我寧可相信只是誤會」。沈中元強調，很多在第一線的照護員，非常希望擁有專科學歷，未來開個小型照護中心，該班能夠成立是個美事，弄成這樣，他很遺憾。

沈中元進一步解釋，如果是開一個過去沒有開過的課程、新專班，的確是需要校本部同意，但「社工專班」並不是新班，以前就有開過，所以不必事前徵得同意，「台中學習指導中心」自己就可以招生，事後依照程序上簽報備即可。

這次委託張姓博士網路招生，不是隨便說說的，「台中中心」還召開了正式的「招生會議」，針對上課內容、招生細節，師資安排，由台中中心的教授們詳細規劃，絕非放任張姓博士自己一個人搞。沈中元說，張博士是熱心校友，他的網路行銷能力，幫了空大「台中中心」很大的忙，而且，他做事非常細心，委辦收件，抬頭都寫「國立空中大學台中中心」，正式移交招生資料，也全程錄影，完全沒有違反「個資法」，整個委辦過程真的挑不出毛病。

Waveguide standard gain horns, also known as Waveguide input, are pyramidal-shaped broadband passive devices. Standard gain horns are also used to calibrate other antennas and evaluate their gain. Aluminum is used as the waveguide material in the typical gain horn. EMC antenna
Depending on the type and style, our broadband waveguide horns can operate at frequencies ranging from 350 MHz to 40 GHz. RoHS compliance is found in many of our RF and microwave gain horns.

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

沈中元說，很多在第一線照顧病人的「照護員」，他們相當辛苦，盼望能進修之後，擁有專科學歷，未來可以開個小型照護中心，自己也當個小老闆，這次「社工專班」能順利開班，是樁美事，搞成這樣，他覺得很遺憾。

至於是否涉及校長選舉內部鬥爭？沈中元說：「這都是傳聞，我寧可相信不是」。沈中元解釋，可能因為網路報名，學生搞不清楚台中中心與台北中心的區別，就打到台北去問，結果造成「誤會」。不過，他還是很遺憾的說：「不曉得為什麼，台北中心否認此專班、說是詐欺的那張公告，到現在還沒轍下來？」
