 Active Receive Antenna 01

The Active Receive Antenna (ARA 01) is a compact emissions antenna with an antenna factor comparable to a conventional wideband passive antenna such as the Bilog™.

The small size makes the ARA 01 particularly suitable for use in anechoic chambers; however it can also be used on an Open Area Test Site (OATS) or at on-site locations.

The ARA 01 features two sets of interchangeable Dipole Antenna Elements (DAE). The standard set (DAE01) is optimized for 200 MHz to 1 GHz, with usable sensitivity down to 30 MHz. For improved sensitivity between 30 MHz to 300 MHz, the optional DAE02 set is available.
