coNNectioN of ANteNNA ANd power Supply
The FT-410 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the
desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is
as close as possible to the specied 50-Ohm value. Note that the “G5RV” type antenna does not provide 50-
Ohm impedance on all HF Amateur bands, and an external wide-range antenna coupler must be used with
this antenna type.
Any antenna to be used with the FT-410 must, ultimately, be fed with 50 Ohm coaxial cable. Therefore, when
using a “balanced” antenna such as a dipole, remember that a balun or other matching/balancing device
must be used to ensure proper antenna performance.
Warning!
The 100V RF voltage (@100 W/50 Ω) is applied to the TX RF section of the transciver while
transmitting.
Do not touch the TX RF section absolutely while transmitting.
CAUTION
Permanent damage can result if improper supply voltage, or reverse-polarity voltage, is applied
to the FT-410. The Limited Warranty on this transceiver does not cover damage caused by
application of AC voltage, reversed polarity DC, or DC voltage outside the specied range of
13.8V ±15%.
When replacing fuses, be certain to use a fuse of the proper rating. The FT-410 requires a 25A
fast-blow fuse.

CAUTION
Do not position this apparatus in a location with direct exposure to sunshine.
Do not position this apparatus in a location exposed to dust and/or high humidity.
Do not expose the apparatus to dripping or splashing. Do not put objects with liquids on the
apparatus.
Ensure adequate ventilation around this apparatus, so as to prevent heat build-up and
possible reduction of performance due to high heat.
Do not install this apparatus in a mechanically-unstable location, or where objects may fall
onto this product from above.
To minimize the possibility of interference to home entertainment devices, take all
precautionary steps including separation of TV/FM antennas from Amateur transmitting
antennas to the greatest extent possible, and keep transmitting coaxial cables separated
from cables connected to home entertainment devices.
Be absolutely certain to install your transmitting antenna(s) such that they cannot possibly
come in contact with TV/FM radio or other antennas, nor with outside power or telephone
lines.
About coAxiAl cAble
Use high-quality 50-Ohm coaxial cable for the lead-in to your FT-410 transceiver. All efforts at providing an
efcient antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes
standard “M” (“PL-259”) type connector.

GrouNdiNG
The FT-410 transceiver, like any other HF communications apparatus, requires an effective ground system
for maximum electrical safety and best communications effectiveness. A good ground system can contribute
to station efciency in a number of ways:
It can minimize the possibility of electrical shock to the operator.
It can minimize RF currents owing on the shield of the coaxial cable and the chassis of the transceiv-
er. Such currents may lead to radiation, which can cause interference to home entertainment devices
or laboratory test equipment.

It can minimize the possibility of erratic transceiver/accessory operation caused by RF feedback and/or
improper current ow through logic devices.
An effective earth ground system may take several forms. For a more complete discussion, see an
appropriate RF engineering text. The information below is intended only as a guideline.
Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If
multiple ground rods are used, they should be positioned in a “V” conguration, and bonded together at the
apex of the “V” which is nearest the station location. Use a heavy, braided cable (such as the discarded
shield from type RG-213 coaxial cable) and strong cable clamps to secure the braided cable(s) to the ground
rods. Be sure to weatherproof the connections to ensure many years of reliable service. Use the same type
of heavy, braided cable for the connections to the station ground bus (described below).
Inside of the station, a common ground bus consisting of a copper pipe of at least 25 mm (1”) diameter
should be used. An alternative station ground bus may consist of a wide copper plate (single-sided circuit
board material is ideal) secured to the bottom of the operating desk. Grounding connections from individual
devices such as transceivers, power supplies, and data communications devices (TNCs, etc.) should be
made directly to the ground bus using a heavy, braided cable.
Do not make ground connections from one electrical device to
another, and thence to the ground bus. This so-called “Daisy-
Chain” grounding technique may nullify any attempt at effective
radio frequency grounding. See the drawing at the right for
examples of proper grounding techniques.
Inspect the ground system - inside the station as well as outside
- on a regular basis so as to ensure maximum performance and
safety.
Besides following the above guidelines carefully, note that
household or industrial gas lines must never be used in an
attempt to establish an electrical ground. Cold water pipes may,
in some instances, help in the grounding effort, but gas lines
represent a signicant explosion hazard, and must never be used.

iNterfAciNG to other liNeAr Amplifier
The T/R control line is a transistor “open collector” circuit, capable of handling positive amplier relay coil
voltages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear ampliers for
different bands, you must provide external band-switching of the “Lin Tx” relay control line from the “TX GND
OUT” line at the LINEAR jack.
Important Note!
Do not exceed the maximum voltage or current ratings for the “TX GND OUT” line at the LINEAR jack.
This line is not compatible with negative DC voltages, nor AC voltages of any magnitude.
Most amplier control relay systems require only low DC voltage/current switching capability (typically,
+12V DC at 25 ~ 75 mA), and the switching transistor in the FT-410 will easily accommodate such
ampliers.
