蓮花改用AMG引擎 馬力卻很悲劇

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

英國蓮花跑車(Lotus)創辦人查普曼(Anthony Colin Bruce Chapman)是個造車鬼才，他專注在底盤設計，因此早期蓮花賽車動力雖然輸別人卻能拿下冠軍，就是因為精湛的底盤技術，但是一輛跑車如果沒有足夠的動力，很難在兢爭激烈的市場中生存，蓮花也明白這個道理，因此全新推出的Emira，入門版改用AMG的M139引擎。

AMG M139引擎大有來頭，是AMG A45採用的動力單元，最強的A45 S馬力高達421匹，排量卻只有2.0升，每公升能換取210匹馬力，被譽為史上最強2.0升引擎；由於這具引擎體積小且重量輕，很適合用在小型跑車，正好蓮花只做小跑車，因此Emira配M139非常適合。

照理來說Emira配上M139引擎性能會比A45 S更好，因為Emira車身更小也更輕，但是AMG藏了一手，他們提供給蓮花的M139引擎最大馬力只有360匹，蓮花官方也沒有說明為何Emira的引擎少了61匹。

Emira高階版則是維持與豐田合作，採用3.5升V6機械增壓引擎，最大馬力400匹，或許就是避免M139引擎馬力高過豐田V6，因而把M139馬力調降到360匹，但是在後續改裝潛力來看，兩具引擎都有很大的改裝空間，而Emira入門價為8.6萬美金(約台幣240萬)，高階版9.3萬美金(約台幣260萬)。

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
