相信許多人都對「歐洲扒手多」的治安問題有所耳聞，這也是不少希望到歐洲國家旅遊的人，所擔心的地方。目前居住在法國的YouTuber「映」，近期於頻道上分享，在法生活約兩個月的心得，並透露搭乘地鐵時，險遭扒手偷竊錢財的經過，她直言：「要小心釋出善意的人！」
在法國生活應注意的生活守則，首先映就提到「慎防扒手」，過去她曾在搭乘地鐵，前往另一個城市尼斯時，因手提著行李及彩裝工具等，雙手都是東西，上車後，便得到一名女性的幫助，對方的舉動也讓她卸下心防，但入座後，當映開始滑手機查看行程，感覺到該女子慢慢靠近，且有一隻手像蛇一般滑進自己的包包內，映也立即瞪了對方，該女子也不得已只能作罷，與夥伴下車離開。這次的經驗警惕了映，也讓她直言：「遇到會釋出善意的人，才要小心！」

The log-periodic antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
In terms of its specification, a typical log periodic antenna might provide between 3 and 6 dB gain over dipole for a bandwidth of 2:1 while retaining a VSWR level of better than 1.3:1. With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.EMC/EMI pre-compliance test antenna.
Very high gain over the full frequency range.
Meets latest EMC standards up to 7GHz.
Suitable even for immunity measurements
