Horn antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
The horn is suitable for both transmitting and receiving purposes, with applications:
- Antenna measurement
- Communication systems
- Satellite tracking systems
- Radar Detection System
- Surveillance System
- Electromagnetic Compatibility Testing (EMC test)
Recommended Accessories
- Antenna Tripod: easy and fast-changing position. 100% stable after installing.
- SMA Cable: High-quality special SMA cable

綜合外媒報導,50歲漁夫沃斯特(Ben Vorster)和哈特(Gerhardt Vorster)、羅斯(Michiel Ross)3人,近日在維德角群島(Cape Verde)進行為期6天的捕魚活動,沒想到他們釣到一隻大西洋藍槍魚,體型是一般的2倍。
他們指出,藍槍魚上鉤後一直沉在水底,拉上甲板後才知道原來牠那麼大隻,長3.6公尺, 621公斤,尾鰭就有2.7公尺寬,略遜金氏世界紀錄最大藍槍魚635公斤,雖然沒有破世界紀錄,仍是在大西洋捕獲的大第二大藍槍魚。
最後,他們將這條621公斤的藍槍魚分解,分送給維德角當地民眾,這些肉可以讓大家吃好幾天甚至是幾個禮拜。
據《維基百科》資料,大西洋藍槍魚是一種在大西洋特有的旗魚,母魚體型可以是公魚的4倍大,牠的肉質脂肪極高,具高商業價值,除了人類以外少有天敵,國際自然保護聯盟(IUCN)未將藍槍魚列為瀕危物種。
