快篩完「狂打噴嚏」錯了？　醫曝實情：有這感覺才對

-

HA-0218G-NF

Applications:

  •  2GHz to 18GHz
  •  6061 Aluminum metal alloy
  •  Stainless Steel N-female
  •  Taiwan Design, Made in Taiwan

Features:

  • High Power 300W (peak) 150W (Cont)
  •  DC Short lightning protection
  •  Low VSWR
  •  Uniform Gain
  •  Consolidated performance database

The horn antennas of the FT-RF horn double ridged antenna series are characterized by an enormous broad frequency range from 2GHz to 18GHz and very high input powers reach to 300W. The gain increases with increasing frequency up to max 17 dBi. The products are in stock and can be shipped
It is suitable for both transmitting and receiving purposes, especially suitable for microwave and EMC measurements.
This antenna has a more uniform gain and antenna factor because of the better behavior of its radiation pattern.

For EMC/ EMC testing: 

  • Pre-compliance testing lowers the chances of certification failure.
    You can make adjustments throughout the design phase with pre-compliance testing.
    Fixing issues after compliance testing are far more costly and time-consuming than fixing them at the design stage.
    Pre-compliance testing might concentrate on the areas where you are concerned about potential issues.
    Instead of looking for faults, pre-compliance testing focuses on identifying solutions.

國內本土疫情進入高原期，單日確診病例均維持在4萬多例間上下浮動。即便家用快篩上路已經將近半年多的時間，不過仍有許多民眾出現超囧狀況「明明在家篩呈陰性，到醫院、診所後結果卻變陽性」為此，知名小兒科醫師黎博彥揭錯誤關鍵。

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

「大家真的是對自己太溫柔了」黎博彥表示，之前也提過鼻咽取樣正確的話，喉頭會覺得有胃食道逆流的感覺，像喉嚨卡卡那樣，若出現猛打噴嚏、鼻子很酸，那麼八九不離十是錯誤的。

再來，黎博彥直呼請大家對自己不要太客氣，若真的鼻子戳不下去，就換換唾液快篩，同時一定要記得「撈一撈喉嚨、有催吐的感覺」才是真的有篩對。

底下留言區有網友發問「所以深度是從棉棒起始點到刻度線（快8cm）全進鼻子裡這樣深度夠嗎？」黎博彥則回應，建議直接握住棒子尾端、插入到手碰得到鼻孔為止，基本上戳對地方就不會痛。
