We are a supplier of military antenna equipment to many countries and are now establishing ourselves as a manufacturer of military antennas for a number of European countries - with an agent in Turkey. We believe that our ability to design and manufacture will meet the needs of all customers. Our military antennas meet military specifications. We manufacture a wide variety of antenna jammers, handheld and manpack antennas, antenna goosenecks, antenna whips, and so on. With a Mast antenna - AM-D120-HA135-RA - the product meets MIL- standards, has a payload of 30Kg, a mast lifting time of fewer than 5 minutes, and can be performed with a Control box or hand-held controller. The product also includes an Emergency Button and an automatic stop system. Furthermore, the product MJ-05M06G03A-NF - one of the most popular today - is 1.5kg light, has high features, and is simple to install, with frequency levels ranging from 500MHz to 6GHz, 3DBi. Not only that, but for many years we have been a supplier of FT-7500 - Marine antenna for the region.

在前期發佈過部份規格後，Formula E 的第三代賽車 Gen3 日前履約在摩納哥 E-Prix 上正式表態了。這款將在 2022 至 2023 賽季投入利用的新車在效能和效力上做了大幅改善，用 FIA（國際汽車結合會）的話來講它有望成為「全球最高效的賽車」。他們之所以敢這麼說，首要是因為 Gen3 在Gen2 原有 350kW 後驅動機電的根蒂根基上，又增添了用於動能收受接管的 250kW 前置機電。如許一來，車輛在比賽中利用的能量會有 40% 來自於制動能量收受接管，這也能讓 Gen3 成為了「首款前後動力系統方程式賽車」。另外因為前動力系統和其能量再生能力的存在，Gen3 也是第一輛不消配備後部液壓抑動器的方程式賽車。

固然，Formula E 也沒有遺忘在永續成長上做出新的起勁。在 Gen3 上他們融入了所謂「Life Cycle Thinking」的概念，簡單來講就是要付與可收受接管的輪胎、組件、電池「第二次生命」。別的在新手藝的加持下，Gen3 選擇的全新 Hankook 車胎利用了 26% 的永續材料，新車的組件也有部份脫胎自 Gen2 的收受接管物料。Formula E 稱 Gen3 是一輛淨零碳排賽車，這也跟他們力圖將賽事打造成第一項淨零活動的目的符合。

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

- 天線三腳架: easy and fast-changing polarisation. 100% stable handling

- SMA Cable: High-quality special SMA cable

至於車體外型，Gen3 要比 Gen2 更小、更輕。它去掉了前後輪罩，整體更像開輪式的賽車。後輪上沒有零丁的翼片，但車後方有兩個靈感取自戰役機的「鰭」，現實上 Gen3 整車的空氣動力學設計都取得了戰役機的啟發。Formula E 官方認為如許的改動能令比賽更具文娛性，新車會更合適「城市賽道上車輪與車輪之間的戰役」，賽道上更多的對決排場可望給觀眾帶來更刺激的鑒賞體驗。

有了 600kW 總功率打底，Gen3 能到達每小時 322 公里的最高車速，百公里加快時候也僅需 2.5 秒。作為比較，F1 賽車在競賽時的平均速度大約在每小時 350 至 370 公里之間。不外以輸出效力來講，Gen3 的功率重量比差不多是內燃機車款的兩倍。並且電驅動系統能將 90% 以上的能量轉化為機械動力，比擬之下內燃機的轉化率就只有約 40%。
