Questions to Ask When Looking for an EMC Immunity Antenna

Antennas come in many different types, and it can sometimes be overwhelming to decide which one fits the need the best. In the case of immunity antennas, the correct selection may be the difference of reaching field and not. The antenna is the most important part of the system. Given that the amplifiers can be the costliest part of the system, one needs to take the time to research and find the correct antenna to make the best use of the available power.
