Active Receive Antenna
Model: ARA 30MHz -
1GHz
The unit is powered from a single PP3
battery. A green LED indicates that the antenna is active, a red LED
indicates that the battery is low and should be recharged or replaced.
There is also an external DC option where the DC is supplied via the RF
cable.
There are two sets of Dipole Antenna
Elements (DAE) which can be used. The unit is supplied with one set as
standard (DAE01). For higher sensitivity at the low frequencies DAE02
should be used. The Active Receive Antenna has
been designed as a compact emissions antenna. The small size makes it
particularly suitable for use in anechoic chambers, however it can also be
used on an Open Area Test Site (OATS). |
