眾人秒發毛！房客深夜下樓拋1問句

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.

▲網友分享，在飯店遇到的奇葩經歷。（示意圖／取自unsplash）

農曆七月即將到來，飯店、醫院皆是鬼故事盛傳的地點，就有一名飯店櫃台分享，某日上班時遇到一位房客阿姨問附近7-11怎麼去，跟對方仔細講解後，隔了兩小時竟又出現同一位阿姨，並拋出一句匪夷所思的問句，貼文引發網友熱議。

根據一名飯店工作的網友於「靠北住宿2.0」分享，某天晚上有位阿姨下樓到櫃台，詢問「7-11怎麼走？」他也禮貌為房客指路「大門出去之後，右轉大約50公尺就到囉！」想不到阿姨繼續問「走50公尺要幾分鐘啦？」

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

阿姨不耐的口氣，讓原PO在心中無奈抱怨，每個人走路的速度又不一樣「誰知道你要走幾分鐘啊！兇屁兇！」不過最後他仍是客氣回答，大約要走3分鐘。

阿姨得到答案後，立刻走出飯店，卻只花了不到2分鐘就又再次經過櫃檯。直到2小時後又再度下來，詢問原PO「欸，7-11怎麼走？」讓原PO感到相當怪異「你剛剛不是才去過？」

貼文曝光後，網友紛紛嚇喊「有影子嗎？」、「你確定看到的是人？」、「你看到的可能不是人」、「不會是地縛靈吧」、「有注意阿姨是用走的還是用飄的？」但也有人猜測，「可能是失智了，體諒她吧」、「原諒她，可能有什麼腦部障礙」、「可能跟我一樣是路癡」。（編輯：鍾怡婷）
