    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-450D 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.

  • Page 14: About Coaxial Cable

    OAXIAL ABLE Use high-quality 50-Ohm coaxial cable for the lead-in to your FT-450D transceiver. All efforts at providing an efficient antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes standard “M” (“PL-259”) type connector.
