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 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.
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 application of horn antenna
- Antenna feeds for parabolic reflectors
- Radar systems with a short-range
The horn is suitable for both transmitting and receiving purposes. the product is 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

討論度越來越熱烈的韓國實境節目《單身即地獄》不論劇情或成員都讓人心癢難搔！一份調查顯示，83%台男直接坦承第一眼會看的就是「身材曲線」，且對於貼身洋裝最無法招架；反觀台女則認為，有著精壯肌肉不是性感的象徵，互動間流露出的體貼和自信才是性感表現！
怎樣才叫性感？交友App《JD》調查男女眼中的性感類型，83%台男坦承對「身材曲線」沒轍，不論是肩線、臀線、腰線等，穿上能夠展露身材優點的洋裝真的很讚，其中有一半男性更提到像是韓國實境節目《單身即地獄》的智雅完全是「性感指標」。
女生則認為過度的展現身材不是性感象徵，過量的「荷爾蒙」反而提不起「性」趣，對於互動上態度大方、自信又體貼的男生還比較有吸引力。
也同時調查男女一眼就愛上的「性感照」類型，高達90%台人一致推「要露不露」的性感照，不管女生是露腰、露腿，男生露手臂或人魚線，總之就是要給人遐想才有吸引力；此外，70%的女生也自爆收過「重點部位」照，不但沒有引起「性」致反而很滅火！
另外，過半台人坦承愛看「健身照」，認為健身照的形象健康性感，更有「體力」保證，絕對會多看幾眼；而比起露胸，男性自認更愛看腿。
