WebHorn Antenna Equation. Horn antenna is used for directional transmission and reception of EM waves. It is an example of aperture antenna. In this structure, the electromagnetic … WebHorn antennas are very directional both for receiving and transmitting so they can both pick up weak signals and transmit a strong signal to a device. This makes them a good choice for both immunity and emission testing. Above 1 GHz a horn is still a good choice and they get physically smaller and more directional as frequency increases. green thai lieferando https://ohiospyderryders.org
