22.11 ANTENNA CONFIGURATION BASIC TERMS AND RULES
For more advanced antenna configurations, it is helpful to define terms used to describe the FLEX-
6000 Signature Series architecture and the rules associated with its configuration.
• A Spectral Capture Unit (SCU) is a direct sampling, wideband digitizer that captures the entire
RF spectrum within its input filter limits.
• The FLEX-6700/6700R models contain two fully equivalent but independent SCUs. The FLEX-
6500 and FLEX-6300 contain a single SCU.
• The FLEX-6700/6700R models can simultaneously digitize two antennas, one for each SCU,
while the FLEX-6500 and FLEX-6300 digitize a single antenna.
• Each Panadapter spectral display requires selection of an associated receive antenna. The
default association for the first Panadapter is ANT1.
• One or more Slice Receivers may be placed on one or more Panadapters.
• Multiple Slices and Panadapters can share a single receive antenna.
• Maestro implements at most two Panadapters and two Slice Receivers.
• In single SCU radios, all Slices must use the same receive antenna. Changing the receive
antenna for a single Slice will change the receive antenna for all Slice Receivers, regardless
of the number of Panadapters.
• In double SCU radios, all Slices placed on a Panadapter must use the same receive antenna
as the Panadapter. Changing the receive antenna for a single Slice will change the receive
antenna for its host Panadapter and all Slices within.
• The receive RF Gain control located on the Slice Receiver’s Antenna Menu is tied to its
respective SCU/ receive antenna combination.
• Transmit antenna selection is completely independent of the receive antenna. Only one
transmit Slice can be active at one time.
• The transmit Slice is selected by tapping the large “TX” button on the Slice Flag, which will
illuminate the button in red, or by pressing the corresponding TX button.
• ANT1 and ANT2 ports allow transmission at 100W on 160m through 6m amateur bands. The
XVTR port allows continuous coverage low power (+10 dBm max) transverter IF from 100 KHz
to 165 MHz.
• Each Slice can have its own transmit antenna selection, which may be the same as or different
from the assigned receive antenna.
• Each SCU on the FLEX-6700 has the option of a dedicated receive-only antenna designated
RX A and RX B respectively. These inputs are hard wired to their respective SCU and may not
be switched between SCUs.
Note: This does not preclude using RX A with ANT2 or RX B with ANT1.
• The single SCU on the FLEX-6500 has the option of the dedicated receive-only antenna input
RX A.
• LoopA and LoopB on the FLEX-6500 and FLEX-6700 are provided to allow connection of
external preamplifiers or pre-selectors. The internal relay switching is identical to RX A and
RX B respectively. However, LoopA and LoopB is a logical designation that assumes that their
input is from one or both of ANT1 and ANT2. This means that a preamplifier installed in
LoopA will be functional if either LoopA or RX A are selected. Logically RX A will assume a
receive-only antenna connected to RX A and LoopA will assume that a device is connected
between RX A IN and RX A OUT.
