I'm looking for suggestions on the best antenna to use for Radiated Immunity test according to IEC 61000-4-3 between 80Mhz and 1Ghz. (we use a dual ridge horn above 1Ghz).
Our goal is to find an antenna which is not too large, yet, will give us good gain at the low end so we can generate 18-20V/m with a 100 watt amplifier. I've looked at the hybrid antennas and they just don't seem to have enough gain at the low end. It appears that most labs that use this type of antenna requires a 200 watt amp. Looks like a Log Periodic has much better gain and should work but we don't want the radials to get too close to the floor. Plus, some of these are nearly 2 meters long. Any suggestions or recommendations? What antenna do you use and how much power do you required to achieve 10V/m with 80% AM modulation without clipping??
