興櫃股星宇航空（2646）股價連日飆漲，甚至成為了航空股王，不過昨日卻遭遇亂流，股價拉回，終場以39.30作收，但在今（22）日開盤以38.8元開出後，跌幅一度超過20%，最低更是來到了32元，也讓星宇航空掉下了航空股王寶座。昨日有網友發文說，自己只是去上個廁所，回來就賠了50萬元。

The 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 s 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 antenna main body with the bracket using CNC precision manufacturing, and adopt a more weather resistant material aluminum material and the surface through the 6061 and 7071 Aluminum special handling to prevent oxidation.
