connected to a UUC (Ultrasonic UpConverter), which is then connected to an
antenna port on the receiver’s ASP-8. The UUC converts the hydrophone’s
acoustic signals to radio signals.

Antennas can be radio or upconverted hydrophones. However, they are treated
as separate groups by the receiver. For example, in an eight antenna
configuration, if radio antennas are connected to antenna ports 1,2, 4, and 6, then
this is referred to as the Radio Group. If the rest of the ports available (3, 5, 7, and
8) are upconverted hydrophones, then they are referred to as the Hydrophone
Group.
If there are no hydrophones used, then there is no hydrophone group
(likewise for radio antennas).

Antennas/hydrophones must be added in the order in which they should be
scanned (scan order). The receiver treats radio antennas as a radio group and the
hydrophones as a hydrophone group (see Understanding Antenna Groups above
for details).
For example, the radio group may be connected to antenna ports 1, 2, 4, and 6,
but if they are entered into the receiver in this order: 4, 2, 1, and 6, then that is
their scan order. The same scenario could apply to a hydrophone group.
Add an antenna to a group via:
Codelog > 1)Config## > 3)Ant (or) 4)Hydr > 1)Radio Ant Grp (or) 1)Acoustic Hydr Grp
The type of antenna must be selected first; selecting 3)Ant proceeds to the Radio
Antenna Group page and selecting 4)Hydr proceeds to the hydrophone group
page.
It is possible to add radio antennas and hydrophones alternately, but it
requires switching back and forth between the radio antenna and hydrophone
pages, which could be time consuming.
