好心幫忙車禍被控傷害 他問:要反告嗎?
彰化一名劉先生，一年多前目擊母子騎車雙載，超越他的機車之後，又超電動代步車，結果擦撞摔車，他看到騎士被機車壓著，好心停下來幫忙扶起來，結果被控告傷害，煎熬一年多，終於獲得不起訴處份。PO文問大家，遇到這樣恩將仇報，是不是要反告?
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.
