INSTALLATION
Antenna Considerations
The FT-2311R is designed for use with an antenna having an impedance
near 50 ohms at thè operating frequency. For optimum performance
use a high-quality, carefully designed antenna. The antenna should be
connected at ali times when power is on, to avoid damage that can
otherwise result if transmission occurs accidentally when no antenna
is connected.
Another i m p o r t a n t consideration in i n s t a l l i n g thè antenna for thè
FT-2311R is thè feedline. For optimum performance use thè shortest
possible length of thè best quality coaxial cable available, and be sure
to use a properly matching fitting (type-N) for thè jack on thè trans-
ceiver.
Mobile Installation
The FT-2311R must only be installed in cars having a negative ground
electrical System. The transceiver should be located where thè dis-
play, controls and microphone are easily accessible, and should be
securely
affixed using thè supplied MMB-33 mobile mounting bracket.
The transceiver
may be installed in any position without adversely
affecting its performance, but it should not be mounted near a heater
vent or where it could interfere with safe operation of thè vehicle.
Make sure that plenty of space is provided at thè rear of thè trans-
ceiver so that air can flow freely around thè heatsink. Refer to thè
diagrams on thè facing page for reversai of thè front panel (if installing
thè transceiver overhead), and installation of thè MMB-33.
(1)
Use thè mounting bracket as a tempiale for positioning thè
mounting holes, after determining thè proper location with
sufficient clearance for thè transceiver. Use a 4.8mm (3/16")
bit for drilling thè holes. Secure thè bracket with thè screws,
washers and nuts supplied, as shown in Figure 1. (Continued
on page 10).

Front Panel Reversai
The front panel may be installed so that it is angled either upward (as
supplied from thè factory), or downward, to accommodate various
installation requirements. To reverse thè front panel;
(1)
Remove thè ten screws affixing thè top and bottom covers, and
remove thè covers, using care not to strain thè speaker wires.
(2)
Remove thè four screws affixing thè front panel, and gently
separate it from thè chassis.
(3) Using care not to pulì on thè interconnecting wiring, turn
thè front panel over, and remount it.
(4)
Replace thè top and bottom covers (now also reversed) and their
ten screws.
