IDA - 3106 Narda
1.3 Narda directional antennas
Three Narda directional antennas that are specially matched to the
IDA - 3106 and which fit the antenna handle are available. They cover the
frequency range from 20 MHz to 6 GHz. A highly sensitive loop antenna is
also available as an accessory for covering the lower frequency range from
9 kHz to 30 MHz.
You can of course also use directional or omnidirectional antennas from
other manufacturers with the IDA - 3106. Even Direction Finding mode is
possible when using the antenna with the antenna handle and adapter.
