Log periodic antennas are our specialty here at A.H. Systems, and on this page you will find a great selection of log periodic antennas, ranging from standard frequency coverage to broadband and folding antennas. 详细
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. 详细
Our Monopole (both active and passive) Antennas provide superior performance in electric field measurements. The Active Monopole Antenna can drive any receiver with 50 ohm input impedance and will perform FCC 详细
A.H. Systems' Preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 20 dB. All of A.H. 详细
The broadband horn antennas BBHA 9120 offer a very low SWR in their nominal frequency range and a very broad bandwidth. The gain increases with frequency up to approx. 21 dBi, depending on the horn's size and shape. The increasing gain with frequency hel 详细
