Isotropic Omnifield Antenna® OFA-G 30MHz-6GHz

May 4, 2013

Omnifield Antenna® Model: OFA-G

A unique broadband active E- field isotropic (spherically isotropic) antenna for RF spectrum monitoring. Connects to any spectrum analyzer, and has frequency response practically independent of antenna orientation or electric field direction. Offers high sensitivity and broad dynamic range for the variety of RF regulatory, safety, EMC, wireless and telecommunications applications.  This antenna is very similar to previous generation OFA-S/SE antennas but has about 12 dB higher dynamic range, extends frequency range to 6 GHz and has much smaller size and weight.

Omnifield Antenna® consists of three parts: antenna head, handle and power unit. Antenna head and handle comprise a single module while power unit is detachable from the handle to allow convenient storage in the supplied rugged plastic case. For normal operation handle must be connected to the power unit to provide power to the antenna head.  Antenna head has 3 antennas positioned normal to each other.  Signals from each antenna are combined and amplified to allow utput signal of Omnifield Antenna® to be proportional to the absolute value of the field regardless of the field direction.  Power unit contains the rechargeable battery and connectors for the antenna and output cable. Ferrite beads, located on this cable, decouple the antenna from spectrum  analyzer and reduce the effects of this analyzer on measured field. This cable also allows operator to have freedom to place the antenna in right position either on non-metal table tripod (supplied with every system) or onto optional 5 feet adjustable tripod.

Selective Field Analyzer SFA-G

Active broadband isotropic antenna combined with portable USB powered spectrum analyzer. OFA-G antenna has frequency response independent of antenna or electric field orientation. It offers broad dynamic range for the variety of RF regulatory, safety, EMC, wireless and telecommunications applications. Spectrum analyzer SA-S/J displays the frequencies and field strength of selected signals, allowing all results to be viewed and stored on PC.

Omnifield Antenna® OFA-G, consists of antenna head with handle and detachable power unit PU-5G. Antenna head has 3 antennas positioned normal to each other. Signals from each antenna are combined to allow output signal to be proportional to the absolute value of the field regardless of the field direction. Power unit contains gain stage, rechargeable battery and connectors for the antenna and output cable.

Spectrum Analyzer SA-S/J is equipped with powerful RF signal processing software, preprogrammed with OFA-G antenna factors, allowing the display of the measurement data in natural field strength or power density units.

There are two variants of spectrum analyzer, having different frequency range: SA-S (1 Hz-4.4GHz) and SA-J (100 KHz-12.4 GHz).
