The Com-Power 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 biconicals 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 a 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-220) which has a mounting head with a matching screw.
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 4.6 dBi over the entire frequency range.
For immunity testing, the input power requirement P in Watts to generate E Electric Field Strength in V/m at a distance in D meters can be calculated by using the following formula:
P = E2 x D2 / 30 x Numeric Gain
G = 20 log F -29.79- AF
G =10 log (Numeric Gain)
Each new antenna is individually calibrated before shipment. The test data will be shipped with the antenna.
