Omni Directional

Overview

Vertical Polarization

Our VBC Series of omni antennas are the best choice when directivity or gain at the horizon is an important factor. These antennas do not need to be mounted on a ground plane.

The VBC antennas are well isolated from the base, resulting in a predictable elevation pattern and reduction in common mode interference.

All VBC antennas are intended for all-weather applications. Antenna elements for VBC antennas are removable for ease of transport and storage.

The VBC-C3059-2, for example, is ideal for tactical applications when quick deployment of the system is critical. All antenna elements fold around the mast section for storage. The antenna can be reassembled from the “storage” to the “in use” position in less than two minutes.

The CMA series antennas are ideally suited for applications where omni coverage at or above the horizon is required and the antenna is mounted on a large ground plane. CMA-118 may be mounted on a ground plane, a tripod or a mast for good omni coverage at or above the horizon.

Also review our Vehicular mounted and Handheld antennas for Law Enforcement and First Responder communication and Jamming networks.  A single antenna may cover all cellular communication bands.

Slant Polarization

The BSB Series antennas are stackable omni antennas which offer excellent performance over a wideband. These antennas are ideally suited for reception of signals on the horizon for nautical and broadband spectrum surveillance applications. The slant linear polarization makes them suitable for receiving vertical, horizontal, and circularly polarized signals.

The stacked antenna models are available with multiple connectors (one for each band) or a single connector for extremely wide band operation.

All BSB series antennas are sealed in low-loss dielectric radomes for shipborne and various outdoor applications.

Vertical Polarization 

SAS-230 series antennas covering 20 MHz to 3 GHz are available with high and low band preamplifiers, which maybe bypassed remotely by integrated low loss coax switches.

Our SAS Series antennas are extremely broadband, portable receive antennas designed specifically for accurate measurement of the vertical electric field intensity. Integral active networks provide outstanding performance over the entire frequency range of operation. This is performance normally associated with full-scale antennas many times larger. All SAS series antennas  for outdoor applications are supplied with protective radomes for outdoor use.

The VBA Series of omni antennas are best suited when directivity or gain at the horizon is important. These antennas do not need to be mounted on a ground plane. The VBA antennas are well isolated from the base, resulting in a predictable elevation pattern andreduction in common mode interference.  All VBA series antennas are intended for all-weather applications. Antenna elements for VBA antennas are removable for ease of transport and storage.

ARA’s ADA Series antennas are electrically small and easily transportable antennas, ideally suited for measuring electric fields and for broadband spectrum surveillance applications. The active circuit design provides a near perfect balance, eliminating the need for a ground plane in the measurement. For applications where antenna sensitivity is critical over a broad frequency range where no suitable ground plane is available, an ADA is your best choice.

CMA-5100/A and CMA-5240 antennas fold into  small volume packages, ideally suited for extremely fast deployment in the field and tactical applications. These antennas  provides excellent coverage at and around the horizon when mounted on a mast.  CMA-5240 is a ruggedized antenna designed for use in harsh environments. CMA-5240 can be operated in a passive or active mode. A new unique design for CMA-5240 antenna elements has reduced the set up time to less than 3 minutes.

Horizontal Polarization

ARA’s ADC Series antennas made for extremely broadband applications to receive horizontally polarized signals and 360 degree coverage in azimuth. Horizontally polarized Omni antennas ADC-2100, ADC-2200 and ADC-2300 cover the frequency bands 20-1000 MHz, 20-2000 MHz and 20-3000 MHz respectively.

The ADC-230 Series antennas  cover the frequency band from 20 MHz to 3 GHz. These antennas are available with high and low band preamplifiers which may be bypassed remotely by integrated low loss switches. ADC-230 antennas can be modified for significantly larger overload protection for use in a high field environment.

Power Supply

Remote and rack-mountable power supplies are also available for use with SAS antennas. These antennas can be modified for use with auto batteries for vehicle mounted applications.

Power supply / Control box, Model PFS-SAS, is recommended for use with the ADC-230 antennas. It provides dc output voltages to drive anADC-230 antenna and also enables the Band/Amplifier bypass switching capability. The PFS-SAS interfaces directly with worldwide AC mains. For controlling purposes, it has a circuitry designed to produce TTL outputs. This provides toggling between different operations modes of Band/Amplifier Bypass/Inline modes.

Vertical Polarization

OVP and RSA Series high gain Omni antennas are used in a wide variety of applications including communication base stations (ground-to-air, point-to-point or mobile communication), Electronic News Gathering (ENG), MMDS and radar systems. Several models are enclosed in special radomes optimized for airborne applications.

The OVP Series antennas include one or more vertically polarized dipoles mounted on a common axis and integrated into a dielectric radome. Multiport OVP antennas have at least 30dB isolation between ports. An internal matching network keeps all antenna parts at DC ground potential.

Horizontal Polarization

The OHP series antennas include one or more horizontally polarized antenna elements mounted on a common axis and integrated into a dielectric radome. Multiport OHP antennas have at least 30dB isolation between ports. An internal matching network keeps all antenna parts at DC ground potential.

STA Series super turnstile antennas are designed to provide omni-directional coverage for communication and spectrum surveillance in the VHF and UHF bands. The super turnstile design allows complete frequency coverage of the VHF/UHF commercial broadcast bands using a single antenna.

STA series antennas offer low to medium gain, low VSWR, and wide frequency bands for transmit applications. By combining single turnstile elements, higher gain can be achieved. An omnidirectional gain of up to 10 dBi can be achieved with a multiple bay antenna. The design is such that from one to eight bays can be constructed on a single modular mast.

One or more super turnstile elements, each covering a different frequency band, can be used in tandem on a single mast to effectively span much wider frequency ranges.

The ARA WDA Series of antennas are optimized for both broadband and high gain performance. These antennas are ideally suited for use with frequency hopping radios and wideband jammers where tuning or band switching is difficult and high gain omnidirectional performance is essential. The sealed radome offers mechanical stability and environmental protection. The antenna elements in a WDA antenna are arrayed and center-fed using a unique method (patent pending) of feeder cable arrangement which creates superb wideband performance with few compromises.
