日本福、城地晚1134分（台晚1034分），生7.3震（最大地震烈度6），局更出海警。根最新消息指出，城在大地震後，出一公尺的海，此外有208住停，目前工程的女川核已停止，正在是否有常。
根洲-地中海地震中心（EMSC）消息指出，此次地震的震7.3 。
Waveguide standard gain horns, also known as Waveguide input, are pyramidal-shaped broadband passive devices. Standard gain horns are also used to calibrate other antennas and evaluate their gain. Aluminum is used as the waveguide material in the typical gain horn. EMC antenna
Depending on the type and style, our broadband waveguide horns can operate at frequencies ranging from 350 MHz to 40 GHz. RoHS compliance is found in many of our RF and microwave gain horns.
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
日本象表示，地震生在海面以下60公里，城在地震生後，出了一公尺的海。
