FTM-10R Operating Manual
antenna installation.
(!) Be certain to wrap any wire or cable splices thoroughly with insulating electrical tape,
to prevent short circuits.
(!) Do not route cables or wires through door jambs or other locations where, through
wear and tear, they may become frayed and shorted to ground or to each other.
(!) Do not stand in front of a directional antenna while you are transmitting into that
antenna. Do not install a directional antenna in any location where humans or pets may
be walking in the main directional lobe of the antenna’s radiation pattern.
(!) In mobile installations, it is preferable to mount your antenna on top of the roof of the
vehicle, if feasible, so as to utilize the car body as a counterpoise for the antenna and
raise the radiation pattern as far away from passengers as possible.
(!) During vehicular operation when stopped (in a parking lot, for example), make it a
practice to switch to Low power if there are people walking nearby.
(!) Never wear dual-earmuff headphones while driving a vehicle.
(!) Do not attempt to drive your vehicle while making a telephone call on an autopatch
using the optional DTMF microphone. Pull over to the side of the road, whether dialing
manually or using the auto-dial feature.
Warning!: The 70.7 V RF voltage (@50 W/50 Ohms) is applied to the TX RF section of the
transceiver while transmitting. Do not touch the TX RF section absolutely while
transmitting.
Antenna Considerations
The FTM-10R is designed for use with antennas presenting an impedance of near 50
Ohms at all operating frequencies. The antenna (or a 50 Ohm dummy load) should be
connected whenever the transceiver is turned on, to avoid damage that could otherwise
result if transmission occurs accidentally without an antenna.
Ensure that your antenna is designed to handle 50 Watts of transmitter power. Some
magnetic-mount mobile antennas, designed for use with hand-held transceivers, may
not be capable of withstanding this power level. Consult the antenna manufacturer’s
specification sheet for details.
Most all FM work is performed using vertical polarization. When installing a directional
antenna such as a Yagi or Cubical Quad, be certain to orient it so as to produce vertical
polarization, unless you are engaged in a special operating situation where horizontal
polarization is used. In the case of a Yagi antenna, orient the elements vertically for
vertical polarization; for a Cubical Quad, the feedpoint should be at the center of one of
