EXTREMELY BROADBAND OMNIS

Transcription

1 A) VERTICALLY POLARIZED, RECEIVE ONLY Our SAS series antennas are ideally suited for spectrum surveillance and spectrum management applications. These 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 fullscale antennas many times larger. All SAS series antennas except for SAS2 alpha antennas are supplied with protective radomes for outdoor use. SAS11/E SAS2 and SAS2/SE antennas are designed for use in environmentally controlled chambers or test laboratories. The SAS2 series antennas have an integrated, rechargeable power supply for stand alone operation. A gradual rolloff in the response below khz in SAS antennas prevents overload due to strong 6 Hz harmonics, in areas where manmade noise is a problem. Some SAS antennas can be modified for significantly larger overload protection when used in a high field environment (see available options for SAS22). SAS22 ON A VEHICLE SAS23 series antennas covering 2 MHz to 3 GHz are available with high and low band preamplifiers which maybe bypassed remotely by integrated low loss coax switches. See separate datasheet for more details related to various options available for the SAS23 antenna. Remote and rackmountable power supplies are also available for use with SAS antennas. These antennas can be modified for use with auto batteries for vehicle mounted applications. SAS22/CR in a mobile Spectrum Management System Telephone Fax (MD) 1877ARASALE (MA) sales@arainc.com 1

3 B) VERTICALLY POLARIZED The SAS23 series antennas are our extremely broadband (from 2 MHz to beyond 3 GHz) omni directional antennas. A complete passive version of the SAS23 antenna is ideally suited for extremely broadband transmit and receive applications. In the transmit mode, they can be utilized to generate large fields (EIRP) for signal jamming, EMC susceptibility testing and other tactical applications. In the receive mode, they can be used for field measurement, spectrum surveillance and spectrum management in the presence of high fields. Three different models of passive SAS23 antennas are supplied with protective radomes. 1) Model SAS23/2 has two connectors; one for low band (2 MHz) and the other one for the high band (83 MHz). 2) Model SAS23/ is similar to SAS23/2 but with a single connector to cover the complete 2 to 3 MHz band. 3) Model SAS23/HP is a ruggedized antenna for use in mobile and military environments. It can handle a significantly larger amount of RF power (in excess of 3W CW over the frequency band, 2 to MHz). SAS 23/HP is supplied in military OD green color.
