ANTENNA CONSIDERATIONS
The FLEX-6400/FLEX-6600 Series radios incorporate a unique smart antenna switching
matrix to simplify connections from your radio to your station antennas. The following is
the signal flow diagram for the FLEX-6400 and FLEX-6600 transceivers:
•
ANT1 and ANT2 can be used for transceiver operation. RXA (and RXB on FLEX-
6600) are for receive only but can be paired with ANT1 or ANT2 for split antenna
operation. The XVTR ports can be used for transverter operation or as an
additional receive antenna port.
•
For very high-speed CW above 60WPM (QRQ mode), separate receive and
transmit antennas should be used to remove any switching delays. The transmit
antenna must be connected to ANT-A or ANT-B and the receive antenna must be
connected directly to RXA or RXB.
Consult the
SmartSDR Software User’s Guide
for a complete description of the operation
and configuration of the FLEX-6400/FLEX-6600 antenna matrix system.

ANTENNA SELECTION
The unique ability of the FLEX-6400/FLEX-6600 to receive continuously over a very wide
bandwidth opens up a new paradigm in amateur transceiver operation. This also changes
how you might consider the proper antenna for your station operation. First, it’s
