保護0-6歲幼兒，6/1起免費提供5劑家用抗原快篩試劑

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

中央流行疫情指揮中心今(27)日表示，目前快篩實名制已有900萬人購買，各藥局據點每日穩定供貨，已不需要排隊。為進一步提供幼兒家庭更足量的家用抗原快篩試劑，及保障無法接種COVID-19疫苗之0至6歲幼兒健康，行政院公布民眾可持0至6歲孩童健保卡(2016年1月1日以後出生之孩童)，至各快篩實名制販售據點免費領取一份5劑家用快篩試劑。

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

指揮中心提醒幼兒家長，家用快篩僅可用於2歲以上幼童，幫2歲以下幼童領取的快篩試劑，可供幼童家長使用，勿使用於2歲以下幼童。
