The FT
5000 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operat-
DX
ing frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio
(SWR) present at the Antenna jack is greater than 3:1, the Antenna Tuner may not be able to reduce the impedance mis-
match to an acceptable value.
It is very important, therefore, to ensure that the impedance of the antenna system utilized with the FT
as possible to the specified 50-Ohm value.
Note that the "G5RV" type antenna does not provide a 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
"balanced" antenna such as a dipole, remember that a balun or other matching/balancing device must be used to ensure
proper antenna performance.
The same precautions apply to any additional (receive-only) antennas connected to the RX ANT jack; if your receive-only
antennas do not have an impedance near 50 Ohms at the operating frequency, you may need to install an external antenna
tuner to obtain optimum performance.
Use high-quality 50-Ohm coaxial cable for the lead-in to your FT
antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes standard "M" ("PL-259")
type connectors, except for the "RX OUT" BNC connector.
