墓地鑽孔做啥？內行抖「真實用途」

-

HA-0218G-NF

Applications:

  •  2GHz to 18GHz
  •  6061 Aluminum metal alloy
  •  Stainless Steel N-female
  •  Taiwan Design, Made in Taiwan

Features:

  • High Power 300W (peak) 150W (Cont)
  •  DC Short lightning protection
  •  Low VSWR
  •  Uniform Gain
  •  Consolidated performance database

The horn antennas of the FT-RF horn double ridged antenna series are characterized by an enormous broad frequency range from 2GHz to 18GHz and very high input powers reach to 300W. The gain increases with increasing frequency up to max 17 dBi. The products are in stock and can be shipped
It is suitable for both transmitting and receiving purposes, especially suitable for microwave and EMC measurements.
This antenna has a more uniform gain and antenna factor because of the better behavior of its radiation pattern.

For EMC/ EMC testing: 

  • Pre-compliance testing lowers the chances of certification failure.
    You can make adjustments throughout the design phase with pre-compliance testing.
    Fixing issues after compliance testing are far more costly and time-consuming than fixing them at the design stage.
    Pre-compliance testing might concentrate on the areas where you are concerned about potential issues.
    Instead of looking for faults, pre-compliance testing focuses on identifying solutions.

清明節快到了，不少人這陣子都在為了掃墓祭祖的事宜而忙碌著，有網友就分享，自己利用假日與家人提前掃墓，但卻發現墓地被鑽了許多不明小孔，因此懷疑有人想盜墓，於是就用蠟燭將洞口封住，但眾人看完紛紛直呼「慘了」、「完蛋了」，並揭露小洞的真實用途。

一名網友在臉書社團「爆廢公社」發文分享了幾張照片，圖中可見，祖先的墓碑上被鑽了幾個小洞，原PO懷疑「有沒有可能是盜墓者行為呢？鑽孔用金屬探測器看看是否有值錢的東西？」，最後和家人討論後，他們則用蠟燭將小洞封了起來。

貼文曝光後，網友們紛紛留言，「完蛋了」、「祖先要生77了」、「這不能這樣封啊大哥」、「裡面會有放什麼值錢的東西嗎」、「這墓是葬骨灰罐的，撿過骨的了，沒有值錢的東西了好嗎！盜墓有這麼不專業嗎？」、「這個已經『撿金』過了不會有人去盜墓的」。

不少網友也留言解釋，其實這些小孔洞，是為了「排水+氣體交換」而打的，「上面比較乾淨的是通氣用的，還有對不準有铣跑掉的痕跡，下面比較髒排水的，而且有段時間了」、「應該是親屬發現裡面積水，找人鑽孔打洞幫助排水」、「一孔排水一孔排氣，一高一低，低的你可以看到水痕，明顯有水有濕」、「把洞填滿，祖先晚上就託夢，要你燒一台除濕機給他」。（編輯：張志浩）

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
