Originally configured for MIL-STD testing. The ALR-30 remote/manual loop antenna transforms magnetic field components by ten passive matching circuits from 9kHz-30MHz and has been designed for use with the Electro-Metrics EMC-30 ( item 100) GPIB controlled receiver but can be used with other 50Ω input systems. It covers the same octave ranges as the ten matching bands of the EMC30 Rx. The matching network switches automatically via TTL when the 7 metres length ACC-25A/30 control cable connects to the Rx.
The antenna can also be used independently with a BCU-25 battery unit which screws into the unit allowing band switching via a front panel rotary switch. Please specify how you wish to use the antenna.
The use of tuned matching transformers increases the sensitivity of the loop whilst reducing the risk of overload across the band. A Thru-Wall Filter (AWF-75) is available for a more permanent set-up where the ACC-25A/30 control cable has to pass through into a chamber. The control cable then comes in two lengths.
