Com-Power AH-220 Double Ridged Broadband Horn Antenna 200 MHz – 2 GHz
Description
The model AH-220 is a linearly polarized broadband double ridged horn antenna operating in the frequency range of 200 MHz – 2000 MHz
The AH-220 Horn antenna is an alternative to Biconical and log periodic antennas operating in the same frequency range for emissions and immunity testing where high gain is needed and the large size of the antenna is not an important factor. For immunity measurements the AH-220 can accept up to 800 Watts input power in a continuous mode.
For easier handling, the AH-220 is constructed using light weight aluminum with a corrosion resistant conductive coating. The mounting bases of Model AH-220 are located near the antenna’s center of gravity. Two mounting bases are provided for vertical and horizontal polarizations. Each mounting base has a 1/4 inch x 20 threaded hole. The antenna can be purchased with an optional Com-Power antenna tripod (Model AT-100) which has a mounting head with a matching screw.
Features
- Broadband – 200 MHz – 2 GHz
- High Gain
- Individual calibration
Com-Power AH-220 Application
The AH-220 horn antenna was specifically designed to make EMC measurements. This antenna is suitable for making EMC measurements per EN 61000-4-3 and MIL-STD 461/462 test specifications.
The distinct advantage of the AH-220 horn antenna is its high gain. This reduces necessary power requirement for generating high field strengths for immunity testing. High gain also increases antenna sensitivity to low level signals during emissions testing. The gain of this horn antenna is at least 6 dBi over the entire frequency range.
