Reference Antennas
Type NRD
-
Reference antennas are precision dipole antennas that offer a fixed 2.15 dB of gain over an isotropic antenna along the major lobe axis at specified frequencies (2.15 dBi). They are intended to be used for antenna field pattern and gain measurements, or general RF sensing in the laboratory.

Biconic Logarithmic Periodic Antennas
Stacked LPDA
-
The stacked Logarithmic Periodic Dipole Antenna consists of two ordinary Log.-Per. structures. The excellent characteristics (flat gain over a large bandwidth, low SWR) of the ordinary Log.-Per. designs could be maintained using the stacked LP design. The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of ca. 2-3 dB compared to an ordinary LPDA. This is especially important for immunity testing, where a maximum fieldstrength and a good field uniformity is required. The beamwidth in the E-plane and the H-plane are nearly identical, providing an optimised illumination of the EuT with minimised ground reflection influence. Further the STLP 9128 C has an excellent cross-polar rejection.

Field Strength Meter
FIM-72A UHF
-
The Model FIM-72A is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-72A is suitable for practically all types of RF emission measurements in the 450 MHz to 960 MHz spectrum. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and meter dynamic range of either 20 dB or 60 dB. A dc analog voltage, proportional to meter indication, is provided for driving a chart recorder or similar device. A leveled output from the calibrating generator is available for measuring cable insertion loss, filter response, amplifier gain, VSWR, and other signal ratio measurements. The 4-1/2 inch, taut band, mirrored scale meter is calibrated in volts and dB for precise measurements in field or laboratory environments.

Biconical Antennas
-
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.

AD-100
-
The Tuned Dipole Antenna model AD-100 is a reference antenna set specified in many EMC standards. It is used in the frequency range of 30 MHz to 1 GHz. This set consists of four baluns and was designed according to American National Standard C63.4. This reference antenna set is used for EMC test site calibrations and for calibrating other antennas, because it is considered a standard antenna according to ANSI C63.5 standard.

High-performance LPDA
ALP690
-
The ALP690 is a high-performance LPDA (log periodic dipole array) antenna with a bypassable, built-in RF amplifier for use with wireless microphone receivers in location or studio production. The design delivers +4 dBd of passive gain in a directional pattern to extend operating range, and, when DC power is applied, the amplifier applies gain to overcome loss in long coaxial cable runs. By offering both active and passive operation modes, the ALP690 can be used as a receiver antenna (active or passive) and as a transmitter antenna (passive only).

Antenna

The multifunctional antennas are designed to meet the harsh environmental conditions and limited space availability found on submarines. This is achieved by utilizing a unique stack array enclosed within a protecting fibre glass dome.The antenna characteristics has been developed in such a way so that aircrafts can also operate in the airspace for data and voice communications next to ship-to-ship or ship-to-shore communications. In this way aircrafts e.g. AWACS act as relay stations to transfer radio signals. Although the dipole of the lizard has a primarily plane oriented radiation characteristic – up until an elevation angle of 60 degrees-, submarines can still track aircrafts up to an elevation angle of 90 degree. This guarantees complete coverage of the surrounding airspace in 360 degree horizontal level as well as in 180 degree vertical level.With this outstanding multifunction antenna capability Aeromaritime significantly extends the military communications for submarines by offering this unique capability.

Lens Antennas
-
A lens antenna is a directional antenna that uses a shaped piece of microwave-transparent material to bend and focus microwaves by refraction, as an optical lens does for light.[1] Typically it consists of a small feed antenna such as a patch antenna or horn antenna which radiates radio waves, with a piece of dielectric or composite material in front which functions as a converging lens to collimate the radio waves into a beam.[2] Conversely, in a receiving antenna the lens focuses the incoming radio waves onto the feed antenna, which converts them to electric currents which are delivered to a radio receiver. They can also be fed by an array of feed antennas, called a focal plane array (FPA), to create more complicated radiation patterns.
