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.
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.
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.
