誤用iPhone1功能!她電話費暴增2百
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
蘋果新機iPhone 14系列今(16)日開賣,甚至連前幾代機種的買氣也跟著上升。然而就有民眾常用iPhone「1功能」,導致電話費暴增2百元,讓她決定發文提醒:別誤用了。
原PO在臉書《爆廢公社公開版》上發文提到,「我的電話費是500多元,但這個月突然暴增2百元,上個月也多1百元」,讓她決定開始追查原因。
後續向電信公司確認後,原PO才驚覺「原來是iPhone 的簡訊裡的這個功能也會收錢,一個記號被收1元」。她提到,自己會在簡訊框長按後,使用出現的表情符號來紀錄,手機內簡訊的中獎序號序號是否兌換過。
遭遇曝光後,立刻有網友驚呼「我也不知道這要收錢耶」、「但我有用這功能,沒收過錢啊」;另外也有果粉解釋「iMessage的訊息表情回應功能,如果對方不是iMessage通訊,他就會傳送一則訊息跟對方提示你有對訊息選擇心情」、「雙方都是蘋果手機平板或電腦,用iMessage發這類簡訊就免費。對方如果不是那就會轉成一般mms簡訊,這個是要收費的」。

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
