FTM-10R Operating Manual
the vertical sides of the driven element (or at a side corner, in the case of a
diamond-shaped Cubical Quad).
Note that this transceiver is designed with wide frequency coverage in the VHF/UHF
spectrum. For general listening, you may wish to have a broadband antenna such as a
discone available, as a directional antenna such as a Yagi will have degraded
performance outside the Amateur band for which it is designed.
Excellent reference texts and computer software are available for the design and
optimization of VHF and UHF antennas. Your dealer should be able to assist you with
all aspects of your antenna installation requirements.
Use high-quality 50 Ohm coaxial cable for the lead-in to your FTM-10R transceiver. All
efforts at providing an efficient antenna system will be wasted if poor quality, lossy
coaxial cable is used. Losses in coaxial lines increase as the frequency increases, so an
8-meter-long (25’) coaxial line with under 1 dB of loss at 144 MHz may have a loss of 3
dB or more at 446 MHz; choose your coaxial cable carefully based on the installation
location (mobile vs. base) and the overall length of the cable required (for very short
runs of cable in a mobile installation, the smaller, more flexible cable types may be
acceptable).
For reference, the chart below shows approximate loss figures for typically-available
coaxial cables frequently used in VHF/UHF installations.
In outdoor installations, be certain to weatherproof all connectors thoroughly, as water
entering a coaxial cable will cause losses to escalate rapidly, thus diminishing your
communications effectiveness. The use of the shortest possible length of the highest
quality coaxial cable that fits within your budget will ensure the best performance from
your FTM-10R.
Mobile Installation
The FTM-10R must only be installed in vehicles having a 13.8 Volt negative ground
electrical system. Mount the transceiver where the display, controls, and microphone
are easily accessible, using the supplied MMB-?? Mobile Mounting Bracket.
The transceiver may be installed in almost any location, but should not be positioned
near a heating vent nor anywhere where it might interfere with driving (either visually
or mechanically). Make sure to provide plenty of space on all sides of the transceiver so
that air can flow freely around the radio’s case. Refer to the diagrams showing proper
installation procedures.
