Antenna Considerations
The FTDX101D is designed for 50 Ohm resistive impedance at the amateur operating frequencies.
6HOHFWWKHSURSHUDQWHQQDGLSROHDQWHQQD<$*,DQWHQQDFXELFDOTXDGDQWHQQDHWFVXLWDEOHIRUWKH
chosen operation and bands.
Construct the antenna and coaxial cable, or use a suitable antenna tuner, to maintain the impedance pre-
sented to the FTDX101D antenna connector for an SWR of 1.5 or less. Careful preparation of the antenna
and/or tuner will permit maximum performance and protect the transceiver from damage.
High voltages may be present on the antenna; install it so it will not be easily touched when in operation.
Connection of Antenna and Power Cables
Please follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as
well as the DC power cable.

GND
Use this terminal to connect the transceiver to a
good earth ground, for safety and optimum perfor-
mance. Use a large diameter, short braided cable
for making ground connections.
DC IN
This is the DC power supply connection for the
transceiver. Use the supplied DC cable to connect
directly to a DC power supply, which must be capa-
ble of supplying at least 23 A @13.8 VDC.
RX OUT A
This RCA jack provides output of the receiver signal
lines from the Antenna jacks which are connected
to “RX” side of the transceiver’s main T/R switching
circuitry.

TX-GND
This RCA jack’s center pin is closed to ground while
the transceiver’s transmitter is engaged. The tran-
sistor open collector circuit used for this jack is ca-
pable of switching a DC voltage of 60 V at 200 mA,
or DC 30 V at up to 1Amp.
PTT
This RCA input jack may be used to provide manu-
al transmitter activation using a foot switch or other
switching device. Its function is identical to the
[MOX] key on the front panel. Open-circuit voltage
is +5 VDC, and closed-circuit current is 2 mA.
RX OUT B
This RCA jack provides output of the receiver signal
lines from the Antenna jacks which are connected
to “RX” side of the transceiver’s main T/R switching
circuitry.
+13.8V
This RCA output jack provides regulated, sepa-
rately fused 13.8 VDC at up to 200 mA, to power
an external device such as a packet TNC. Make
