Installation and Interconnections

Antenna Considerations

The FTDX101MP/FTDX101D is designed to connect to a 50 Ohm resistive impedance antenna at the
Amateur operating frequencies. Select an appropriate antenna (dipole antenna, YAGI antenna, cubical
quad antenna, etc.) that is suitable for the chosen operation and bands.
Construct the antenna and coaxial cable, or use a suitable antenna tuner, to maintain the impedance
presented to the FTDX101MP/FTDX101D antenna connector for an SWR of 1.5 or less. Careful prepara-
tion of the antenna and/or tuner will permit maximum performance, and protect the transceiver from dam-
age.
High transmitter RF voltages may be present on the antenna; install it so it will not be easily touched when
in operation.

Antenna Connections

Carefully follow the illustration regarding the proper connection of antennas and coaxial cables.
To prevent damage from lightning, atmospheric electrical
discharges, electric shock etc., provide a good earth ground.
Use a short, thick, braided cable to connect the station equipment
to the buried ground rod (or alternative earth ground system).
