The Aaronia 727 PowerLOG Horn Antenna, 4GHz to 40GHz features horn antennas characterized by an enormous broad frequency range and very high input powers. The gain increases with increasing frequency up to max. 17 dBi. This gain increase compensates the increasing cable losses at higher frequencies. The PowerLOG 40400 is suitable for both transmitting and receiving purposes. Due to the very high maximum transmission power of up to 300W (peak), the PowerLOG is especially suitable for EMC and immunity test measurements. The antenna is delivered including specific calibration data.
