阿翔帶辣妻朝聖張惠妹演唱會 「看到一半」快閃離場
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
阿翔的老婆Grace在Instagram發文透露，自己到小巨蛋朝聖張惠妹的演唱會，直呼「耳朵好享受喔」，只不過卻聽到一半就無奈離席，原來是趕著回家照顧小孩，「走得很心不甘情不願」。
雖然走得心不甘情不願的，但回到家中看到3個小孩安心地睡得東倒西歪，讓她相當遺憾，並直言自己等張惠妹的演唱會等了7年，卻沒法全程看完而感到難過。
而她聽演唱會為了小孩中途離席奔回家中的舉動，也引起不少網友討論，紛紛留言「爸媽歌迷真的辛苦了」「有小孩果然不能盡興聽演唱會啊」「好羨慕，超想看的」。
