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.

空軍司令部今（14）日表示，本屬新竹基地一架幻象2000-5戰機（機號2017），今上午10時許於台東志航基地起飛，執行例行戰訓任務，於空域回報機械故障返場，11時26分在台東志航基地南面10浬呼叫彈射跳傘，空軍表示，隨即派遣UH-60M赴現場，於12時06分完成人員吊掛，人員獲救情況良好，並送醫觀察。空軍司令部進一步表示，已組成專案小組赴台東志航基地，以釐清事件肇因。
