25.11 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, and 6600(M) models contain two fully equivalent but independent
SCUs. The FLEX-6500, 6400(M), and FLEX-6300 contain a single SCU.
 The FLEX-6700, 6700R, and 6600(M) models can simultaneously digitize RF from two
separate antennas, one for each SCU, while the FLEX-6500, 6400(M) and FLEX-6300 digitize
RF from a single antenna.
 Each Panadapter spectral display requires the 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 dual 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 and 6600(M) has the option of a dedicated receive-only
antenna designated RX A and RX B respectively. These inputs are hard-wired to their
respective SCUs and may not be switched between SCUs.
Note: This does not preclude using RX A with ANT2 or RX B with ANT1.
 A single SCU radio 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 ANT1 and ANT2 ports. This means that a preamplifier
installed in LoopA will be functional if either LoopA or RX A is 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.
