We provide measurement and calibration Tests, ODM, OEM services for certain products.

We have hundreds of customers from over 60 countries, and to meet their demands, we developed a plant in Vietnam (with a total infrastructure area of 10000 square meters, which includes three major buildings dedicated to operations and production) in addition to the main manufacturing facility in Taiwan. Now, we are focusing on automatic production lines and investing in automation equipment. In the future, we pledge to deliver the highest-quality product in the shortest possible period.

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

「保險套」是現今最常見的避孕方式，但是在古時候，避孕方式大多使用「動物的腸衣」，有點類似現今的保險套，但古代是用動物的腸衣製作而成的，不過做出來的質感較粗糙也比較厚，但外觀的樣子與現代的保險套已十分接近。

▲在古代用來避孕的魚泡，在現今竟是一樣美味的食材。（圖／翻攝微博）

古代的保險套多數使用「魚鰾」，也可能為魚泡，避孕效果非常良好，且對身體不會造成傷害，因此成為古代最熱門的避孕方式。沒想到在古代用來避孕的魚泡，在現今竟是一樣美味的食材，市面上多數販售曬乾的魚泡，加入清水浸泡後就可以炸著吃、紅燒、煮湯等，口感細膩爽滑，可說是美味佳餚！

根據本草綱目記載「魚鰾膠稠，入腎補精，恐性膩滯，加入人參，以氣行於其中，則精更益生，而無膠結之弊也。」魚泡含有豐富的蛋白質、維生素及礦物質等營養成分。
