狗狗拒吃潔牙骨！每天堅持要看把拔「表演魔術」才肯吃網笑翻：主人被訓練得真好～

In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.

A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing

大部分的狗狗看到主人拿零食給牠們時，應該都會迅速地把它吃掉，避免心愛的零食被搶走，不過這隻汪星人卻很不一樣！根據DailyPaws的報導，國外網友凱比歐拉（Gabriella Armato）家中養了一隻非常聰明的澳洲牧羊犬，日前她在TikTok上分享了一段影片，只見凱比歐拉的爸爸拿著潔牙骨要給狗狗吃，可是狗狗卻板著臉撇頭拒絕，而牠不馬上接過潔牙骨並不是因為牠不想吃，而是因為把拔還沒表演「魔術」給牠看！

「本汪就是任性～」

把潔牙骨變不見！

影片中可以看到，當凱比歐拉的爸爸準備要變魔術時，狗狗立刻露出笑容，專注地盯著把拔看，似乎很期待把拔這次會表演什麼新招式。凱比歐拉的爸爸先是把潔牙骨從手中變不見，接著又假裝把它吃掉，最後再將潔牙骨從雙手中慢慢推出來，表演結束後，狗狗才心甘情願地咬著潔牙骨到牠的床墊上享用，這位爸爸真的是為了維護狗狗的牙齒健康，很賣力地在演出耶～

潔牙骨竟然從把拔的嘴裡跑出來！

表演完後狗狗才心滿意足地咬走潔牙骨。

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

整個表演過程中，狗狗目不轉睛盯著把拔看，更搞笑的是，每當把拔做出一個令人驚奇的招式，狗狗就會興奮地汪汪叫，像是在發出驚嘆聲，天真可愛的模樣萌翻了網友們。影片被分享到網路上後，至今已經累積超過四百萬觀看次數，不少網友紛紛留言笑說：「到底是誰訓練了誰XD」、「汪表示：我訓練我的主人表演魔術給我看耶！」、「通常應該都是狗狗表演特技吧！」、「沒有魔術就不吃，一切免談」。
