oNNectioN 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 specied 50-Ohm value. Note that the “G5RV” type antenna does not provide 50Ohm 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 specied 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.
