9- Antenna memory per band
The MBD-8G has a memory for each of the eight antennas so that whenever an antenna is
selected this memory registers the band selected by the Radio. With each band change in the radio
the MBD-8G will activate the last antenna that was used in that band.
Note: The setting mode is only possible when the Radio is properly connected to the MBD-8G.
10- Connectors description (connector # on rear panel image)
a- Band Data Out (#3)
The DB-9 Band Data Out connector on the rear of the MBD-8G provides a Band Data output
that matches the frequency of the radio that is connected. When the MBD-8G receives the band
information from the Band Data, this same information will be passed to the Band Data Out
connector. When receiving the information through Frequency the conversion to Band Data will be
done according to the table in item 8.
