A.H. Systems Inc.
Loop Antennas Loop Antennas 20 Hz - 30 MHz. A.H. Systems manufactures a wide variety of loop antennas in the frequency range of 20 Hz to 30 MHz. Loop antennas are primarily used to measure the magnetic field strength at lower frequencies. The small size of these loop antennas has the advantage of convenience in handling, availability of a zero- response orientation, and a simple expression for the voltage produced by a given field strength. At higher frequencies, about above 100 MHz, a loop of practical size... (read more)Browse Antennas Datasheets for A.H. Systems Inc. -

How to use Antenna Factors How to use Antenna Factors. What is an Antenna's "Antenna Factor"?. An antenna's antenna factor (AF) is a comparison between the field level presented to the antenna and the actual voltage produced by the antenna at it's connector. The antenna factor varies with frequency, that is for the same presented field strength, but at a different frequency, the voltage produced at the connector is not constant. Creating the AF Data. By way of further explanation, a not particularly accurate yet simple... (read more)Browse Antennas Datasheets for A.H. Systems Inc. -
