The active monopole antenna VAMP 9243 consists of a vertical rod and an impedance matching amplifier. The rod has a standard length of 1m (other rod length on request) and can be considered as short compared to the wave length in the frequency range 9 kHz-30MHz.

The conversion factor is independent of the frequency because of the extremely high impedance of the matching amplifier.

Dipole antenna is used to transmit and receive signals of fixed frequency. Dipole antenna is needed in the field attenuation and antenna coefficient measurement. The frequency range of dipole antenna covers 30MHz ~ 4GHz. Among them, vhap and uhap are a set of precise dipole antennas, which are especially suitable for field attenuation and antenna coefficient measurement.

The biconical antenna fully meets the requirements of CISPR, FCC and MIL-STD standards. It is mainly used in radiation disturbance, radiation immunity test and signal transmission and reception. Biconical antenna is composed of antenna bracket and antenna vibrator. The antenna can be composed according to the needs, or the combined biconical antenna can be selected.

The LPA fully meets the requirements of CISPR, FCC and MIL-STD standards. It is mainly used in radiation disturbance, radiation immunity test and signal transmission and reception. The working frequency can be as high as 18GHz and the power can be as high as 3000W. The antennas are all made of aluminum, light weight. Among them, the vulp9118 series is suitable to be used as a transmitting antenna for Radiated Immunity test due to its high power and large gain.

Stacked Double Log Periodic Antenna is a composite antenna array with two log periodic antennas. Its performance is better than that of a single log periodic antenna: it has a flatter antenna gain and a lower VSWR in the broadband. The stacked design makes the directionality of the antenna in the horizontal plane more centralized, and the gain of the antenna is improved by 2 - 3dB compared with the standard log periodic antenna.

The loop antenna includes active loop antenna and passive loop antenna, which are mainly used to measure the intensity of the radiated magnetic field. The antenna factor of active loop antenna is close to a fixed value in the whole frequency range. It can be used for testing CISPR, mil, FCC, en, ISO, ANSI, ETSI and other standards.

A lot of EMI tests need to be carried out outside the laboratory, and testers usually carry different instruments, equipment, antennas, cables, etc. In order to facilitate the user's field test requirements, we can provide nearly 10 kinds of portable antenna toolbox to meet the user's requirements of carrying out electromagnetic interference test in accordance with CISPR, MIL-STD, FCC, en, VDE, IEC and SAE standards.

The HIRA180S is an ultra wideband half radiating antenna using a ground plane as an electromagnetic mirror. This antenna produces a very narrow beam in the bore sight direction. The advantage of this construction compared to a full paraboloidal reflector antenna is a better ruggedness, a broader frequency range and an improved return loss.
