侯孝賢新作進度曝光！監製老夥伴新片「只負責吃飯」
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

文學紀錄片「他們在島嶼寫作」系列今（22）日舉辦第三系列聯合發表會活動，5部系列新片聚焦7位文學家各具風格的文學生命，擔任當中2部片《願未央》、《我記得》監製的侯孝賢導演，也特別出席活動，與他合作過多部電影劇本的朱天文更透露兩人的新作《舒蘭河上》進度。
朱天文此次親自執導父母親的傳記紀錄片《願未央》，也是《我記得》中的傳記主角，被問到首當紀錄片導演的心得，她直呼過程非常痛苦，「基本上是侯導的拍攝團隊，我才敢接這工作，從事電影17年，這算是電影給我的紅利，侯導團隊基本上不會打擾被拍的人，讓人不會感覺到攝影機的存在。」
侯孝賢聊到此次擔任監製的心情，他透露絕不會打擾朱天文拍片的過程，開玩笑說：「我只負責吃飯。」兩人曾合作過《悲情城市》、《戀戀風塵》、《千禧曼波》、《最好的時光》、《刺客聶隱娘》等多部經典電影，問及新作《舒蘭河上》的進度，朱天文表示，目前都忙於為2部紀錄片宣傳，預計3月會和侯導一同去勘景，一直以來兩人只要有空就會去咖啡廳討論劇本和資料。
《舒蘭河上》描述河神與亞斯伯格症孩子的友誼，朱天文透露，舒淇因為疫情關係還沒辦法回台灣，但她對河神這角色很有想法，像是造型等，侯導都放手讓舒淇去發想。至於張震，朱天文則說他專注在另一部作品《我將前往的遠方》，但他在片中得照顧失智父親，他覺得角色太寫實，對接下這角色有些害怕。
