林明禎擔張敬軒演唱會嘉賓 「長白裙好身材包不住」首站上紅館演唱
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
馬來西亞女神林明禎上月把台灣房子退租，搬去香港長期發展，昨(11)晚更擔任歌手張敬軒演唱會來賓。第一次站上紅館演唱，她身穿白色長裙現身舞台，全場立刻起鬨。她緊張說：「我何德何能站上紅館這個舞台跟你合唱？我今天第一次穿這種裙。」對於歌迷熱烈反應，林明禎興奮不已。

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
林明禎在香港憑甜美外表及火辣身材大受歡迎，早前她擔任按摩椅代言人，透露有意在香港和馬來西亞買房子。最近林明禎又接下日本運動品牌廣告，露出小蠻腰大賣健康美。林明禎一向熱愛運動，每天堅持瑜伽、高強度運動，果然練出一副好身材。
為了拍攝時有更佳效果，林明禎特別進行額外訓練，她認為沒有任何藉口不做運動，只要穿著合適的運動背心，在初夏配以長薄外套跑步，流汗之餘，仍然感到通爽舒適。
