Dipoles
1) electric dipole - is the separation of a negative charge from a positive. 2) magnetic dipole - the closed circuit of an electric current system.

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.

Adjustable Dipole Antenna
SNA600a
-
The SNA600 antenna is a versatile tool for use with wireless microphone receivers or IFB transmitters. The center frequency of its 100 MHz bandwidth is tunable from 550 to 800 MHz. The frequency is set by adjusting the dipole elements using the scale printed on the body of the antenna. The elements fold for storage.

Horn Antennas
-
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. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.

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).

Electrical Tomography Software
Res2dinv
-
This very popular software, developped by M.H.Loke, uses the method involving the Sasaki minimum squares inversion (1992) to produce a 2D sub-soil model starting from the data of apparent resistivity (up to 2000 electrodes). It is completely automatic and does not require that the user formulates a starting model. When using a state-of-art computer, the inversion of a single pseudosection will require only a few minutes.RES2DINV supports spreading types like Wenner, Schlumberger, Pole-Pole, Pole-Dipole, line Dipole, equatorial Dipole and other non-conventional spreading types.

Logarithmic Periodic Broadband Antennas
-
Directional, active broadband antennas that are the ideal solution for interference tracking, site surveying, and most general RF and EMC analysis applications, due to their unique dipole elements positioned along the antenna axis in a triangular shape.

EM-6947 | 200 MHz – 5 GHz
-
The EM-6947 is an ultra-wide bandwidth log periodic dipole array aimed at applications requiring consistent performance over a very wide frequency range. Capable of both receiving and moderate power level transmitting, the EM-6947 can take the place of two or more conventional antennas, allowing you to take full advantage of the tuning range capabilities of modern receiver and spectrum analyzer designs with less inconvenience caused by the need to switch antennas.
