結帳秒氣炸！他吃爌肉飯太油換一碗
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

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
「有店家這麼坑人的嗎？」一名網友在網路上抱怨，他近日到某間餐廳點了爌肉飯，但吃到一半發現太油膩，便整碗退回，要求店家重給一碗新的，未料在結帳時竟被收兩碗爌肉飯的錢，讓他氣炸飆罵店家坑人，貼文曝光後，讓不少網友看傻，留言反轟原PO：「太錯愕了，吃一半收回，要賣給誰，你要嗎？」
喇叭天線
該名網友在「匿名公社」中發文，他表示近期去某間餐廳叫了爌肉飯，不過吃到一半發現太油膩，因此向店家要求換一塊較瘦的，也把吃到一半的爌肉飯退回去，沒想到在結帳時，店家竟要求收兩碗飯的錢，讓他怒罵：「有店家這麼坑人的嗎？肉太油膩根本就是你們的問題！」
貼文一出，網友們全逆風力挺店家，「來亂的，都吃了」、「第一天吃爌肉飯嗎？要肥瘦需求自己不會先說嗎」、「滷肉飯就是會油，如果怕油，跟人吃什麼滷肉飯」、「下次點雞絲飯就好」、「太錯愕了，吃一半收回，要賣給誰，你要嗎」、「應該是美式賣場逛習慣了」。
另外，也有人建議原PO，「你在點餐時應該要先提醒店『我控肉要瘦一點的』，而且送餐點來的第一時間你就要確認瘦肥是否符合你的標準，不能吃了才說太油要換，基本上食品的東西再出餐後是無法再退回的，因爲牽扯到衛生安全的問題」。（編輯：賴禹妡）
