RX ANT OUT Jack
This BNC 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 cir-
cuitry.
RX ANT IN Jack
This type-M jack is for a separate receive-only antenna.
An antenna connected here can be used when the [ RX ]
antenna button on the front panel is pressed.
If you want to use some special kind of external
bandpass filter or preamplifier, you may connect it
between the RX ANT OUT and RX ANT IN jacks.
ANT 1/2 Jacks
Connect your main antenna(s) here, using a type-M
(PL-259) plug and coaxial feedline for each. These an-
tenna ports are always used for transmission, and also
are used for reception unless a separate receive an-
tenna is also used for the receiver. The internal antenna
tuner affects only the antenna(s) connected here, and
only during transmission.
Warning!
The 141V RF voltage (@200 W/50 Ω) is applied to
the TX RF section of the transciver while transmitting.
Do not touch the TX RF section absolutely while trans-
mitting.

DC 13.8 V ... IN Jack
Connect this 6-pin connector to the DC 13.8 V Output
Jack on the FP-2000 AC Power Supply, using the sup-
plied DC Power Cord. This connector provides +13.8
V DC supply voltage for the FT-2000D.
–
DC 50 V ... IN Jack
Connect this 2-pin connector to the DC 50 V Output
Jack on the FP-2000 AC Power Supply, using the sup-
plied DC Power Cord. This connector provides +50 V
DC supply voltage for the power amplifier of the FT-
2000D.
GND
Use this terminal to connect the transceiver to a good
earth ground, for safety and optimum performance. Use
a large diameter, short braided cable for making ground
connections, and please refer to page 9 for other notes
about proper grounding.
μ-TUNE Jacks
These jacks are used for signal input/output of the op-
tional RF μTuning Kit.
