The AH18G active horn antenna allows for precisions noise measurement and identification.
• FREQUENCY RANGE
This antenna covers the 700 MHz Hz to 18 GHz range making it ideal as a receive antenna for any emissions testing above 1 GHz.
• DESIGNED FOR MIL-STD-461
DRHA18G Dual Ridged Horn Antenna, (without pre-amplifier) is identical to the antenna described in MIL-STD-461 RE102, for emissions testing above 1 GHz.
• FITTED AMPLIFIER
The amplifier has a typical gain of 28 dB. The gain flatness across the range is 2.5 dB. The pre-amplifier has a maximum noise figure of 4 dB maximum with the typical noise figure being 3 dB. The power output is +17 dB minimum at the 1 dB point. The input and output characteristics of the pre-amplifier are an input and output VSWR of 2:1 maximum.
