Antenna Port and External Keying Lines
You will next need to configure the antenna ports such that the correct antenna is selected for each
band as well as the correct keying line(s), if any. To do so, click on Antenna in the menu of the Front
Console (Figure 30). We will only describe certain controls at the Simple complexity level here. For
more detailed information, including Expert level, see page 149).
Complexity: Simple uses the same antenna port for all bands, whereas Expert allows you to
select different antenna ports for each band If you use only one antenna, choose Simple.
Antenna: The following selections are possible:
o Receiver 1: ANT1 (default), ANT2, ANT3 or RX1 IN
o Receiver 2: (if installed) RX2 IN (default), RX1 Tap (the same antenna port as selected
for receiver 1), ANT1
1
, or N/C (not connected).
o Transmit: ANT1 (default), ANT2 or ANT3
2
.

Earlier versions of the FLEX-5000, with the HRFIO board Assembly Number (ASSY) 27 installed instead of the later HRFIO
board ASSY 34, do not have ANT1 available as an option for Receiver 2. You can check which board is installed in your
FLEX-5000 by opening the Setup Form – General Tab, Hardware Config Sub-Tab, in the section marked FLEX-5000 Config. The
Assembly Number is shown between brackets at the end of the line beginning with RFIO (see e.g. Figure 64 on page 81). Also
see the Knowledge Center articles HRFIO Capabilities by Assembly Number , How to Identify the HRFIO Assembly Number and
Antenna Selection Options for the RX2 (a search for HRFIO in our Knowledge Center at http://kc.flex-radio.com/search.aspx
will yield all these articles). If you have the earlier HRFIO ASSY 27, you can upgrade to ASSY 34. See the Flex-Radio Systems
website ( http://www.flex-radio.com/ ) for more information.

For the earlier HRFIO board ASSY 27 (see footnote 1 above), the 6m transmit antenna port is fixed to ANT3 and cannot be
changed. Only the ANT3 port meets the -60dBc spurious output requirement at 6m. For the later HRFIO ASSY 34, this is not the
case and the 6m transmit antenna port can be assigned to any of ANT1-3, just like any other band.
