The shipping cartons for the
ASB-850 have been
carefully designed
to protect the transceiver and
accessories during shipmetit. This carton and its
associated packing materials should
be used to
reship the radio.
If
the original shipping carton is not available, be
sure to caref~rllypack each ilnit separately, using
s~iituble
cushioning material. Very special attention
should
be given to providing enough packing
material around controls. connectors. arid other
protrusions from the radio. Rigid cardboard should
be placed at the corners of
the equipment to
protect against damage
if the carton is dropped.

2.4 GENERAL INSTALLATION AND MOUNT-
ING INFORMATION
Satisfactory operation of this equipment will
depend
upon the care and thoroughness taken
during installation.
2.4.1 GENERAL INSTALLATION
a. Carefully plan the Amplifier/Coupler antenna
installation to minimize the length of wire between
the coupler output and the antenna itself. This
lead should be kept as short asphysically possible,
6 inches orless is optimum. The wire inside the air-
craft is
a part of the antenna, but will radiate
inside the fuselage, not outside. This energy may
cause interference with other electronic equipment
in the vicinity. This interference can often be
reduced by using high voltage coaxial cable such
as
RE8/U, between the coupler and the antenna
feedthrough.
The coax must be kept short because
coax lengths longer than 3 feet can cause large
losses, particularly at the antenna resonant and
antiresonant frequencies,
when VSW R exceeds 1 0.
b. The location of the ReceiverIExciter unit is
not critical, and may be placed anywhere there is
available space within the fuselage.
Installation ol !he A mplifierl
Cuupler and ReceiverlExciter
musf conform
to the A ltitudel
Temperature resrrictions detail-
ed in the equipmc~rspecifica-
tions.
c. Install the Remote Control Head in the cockpit
in any convenient location.
d. The installations should be carefully planned
beforehand in accordance with the drawings on the
following pages.
2.5 POWER REQUl REMENTS
The ASB-850 is designed to operate from a
nominal 27.5 VDC + 10%, - 20%, source. The sys-
tem should be connected to the source through
the
aircraft circuit breaker panel. using a 20 ampere
breaker. The Receiver/Exciter receives aircraft
28V
through a 5A SB fuse mounted in the PAICpIr.
All low level voltages used in the Remote Control
are cilrrent limited to safe levels
by voltage regula-
tors and do not require fusing. Power used in the
PA/Cplr is fed through a 10A S0 fuse located in
the PAICplr.
2.6 GROUNDING REQUl REMENTS
2.6.1 GENERAL
It is very important that all ground straps provided
on the mounting racks and
the ground strap attach-
ed to the rear panel of the PAICplr be securely con-
nected to the aircraft frame.The radiation resistance
of some aircraft antennas is q~~itelow, sometimes
less than
1 ohm at the lower frequencies. In order
not
to decrease the efficiency the bonding straps
from the PA/Cplr must be very securely bonded
to the aircraft such that the resistance readings
should
be in the order of 1 milliohm or less from
the aircraft frame to the ground portion of the
antenna RF output connector.
3A 156. Connecting
all ground straps properly should resi~ltin
an ade:
quate ground system.
2.7 CABLE FABRICATION
2.7.1 GENERAL
The cables listed in paragraph 1.5 must be wired go
their appropriate connections as shown in Figure
2.8 Interconnect Wiring Diagram. Cable
Fabrication is shown in Figure 2.9.
All cables are available from Sunair with the excep-
tion of
the audio wiring from the control head con-
nector
2A3J2. Since this wiring must be routed to
various locations in the aircraft instrument panel
the installer should fabricate this cable
using stsn-
dard aircraft installation practices
The document reference is online, please check the correspondence between the online documentation and the printed version.

2.7.2 CHECKS AFTER FABRICATION
2.7.3.1 SYNTHESIZER PROGRAMMING
Each cable must be checked for continuity and
shorts to other pins. All wiring is pin to pin;
"A" to "A", "B" to "B" etc. In order to be certain
the synthesizer is being programmed correctly it
is necessary that the exciter frequency be checked
with a counter as each decade frequency must be
checked from
0 to 9 to verify that the wiring of
cable 8040007500 is correct. See Figure
2.1 for a
recommended test set-up to verify operation on
the bench.
Rotate each frequency switch through all 10
positions and check for the correct frequency
readout on the counter.
2.7.2.2 BAND SWITCHING
Bandpass filters are located in the exciter unit
at the exciter output and low pass filters are
located in the PA/Cplr unit at the output of the
power amplifier. These filters are automatically
switched by the 10 MHz and
1 MHz frequency
switches in the control head.
Operation of these filters may be checked
by
monitoring the power output of the PA in each
band.
Bands are divided as shown below:
Freq.
MHz Band
Connect the equipment as shown
in Figure 2.2.
Turn equipment ON and set mode switch to AM
and set frequency for the middle of each band.
Key microphone and check for power output in
each band. If the bands are not being switched
properly the power will be essentially zero
on the
watt meter in the non-operating band. Note:
The
PA filters are of the low pass type so a low band
frequency could pass through a higher band but
not the reverse.
2.7.2.3 MISCELLANEOUS CHECKS
Other functions that must be verified are shown
in chart form below. Functions such as audio,
squelch,etc are self explanatory and are not shown.

tem first tuned on.

2.8 ANTENNA INSTALLATION
2.8.1 GENERAL
The installation of a high frequency antenna on an
aircraft involves the consideration of several factors.
The shape or configuration of the antenna must
allow the transceiver to transmit and receive as
required by the user. The user or aircraft owner
also i~si~allyhas a requirement regarding appearance
and flight qualities of the antenna and of course
these should be considered by the installer also.
However, as occurs in most things in nature,

what is best for one parameter is not best for
another. The
HF antenna is no exception. What
sometimes occurs
is that the length, shape (con-
figuration) and location of the iIntenna on an air-
craft is something very visible and these factors
receive tlie major consideration. The cornmunica-
tions performance of tile antenna is not readily
apparent or known. partic~~larlyat the time of
installation and decisions are made regarding the
antenna installation which later prove to be bad
for system operation. The solution tlien
is to
select an antenna that does not overly favor any
factor to the detrement of the other factors.
2.8.2 FACTORS TO BE CONSIDERED
In order to select the best antenna, consideration
must be given to the following factors:
I. Type of aircraft
a. Size. shape, airspeed
2. Required con~rnunioationsrange
3. Transmitter frequencies
4. Antenna flight requirements
5. Possible antenna coupler locations
6. Antenna radiatiori ckaracteristics.
Aircraft size and shape is important as it mily re-
strict the types ot possible antennas. Aircraft
speed must be considered. as
160 MPH and faster
type of aircraft cannot generally i~sc
a wing tip
attached
V antenna. This type OF aircraft rnay also
operate in icing conditions which adversely affect
V antennas more than t11c straight type.
The end users commu~iicationsdist;lncr retluire-
ments must be considered, particularly if long runge
such as
800 rniles and greater is reqttired on
freq~~enciosas low as 0 to 8 MHz. This would re-
quire a
V antenna or a long straight antenna 35
feet or longer, if ungrounded.
Transmitter freqi~encies
arc getlerully determined
by the area of operation and statiotls to be worked.
These in turn can affect the aritenlla selection. If
most of the freqi~e~iciesare
above 5 MHz it is
possible to use
a shorter or srraiglit atitrn~iaas
coi~plerefficiency above 5 MHz is good regardless
of the antenna type.
The antenna uerodyt~arnicrerluirrmc.~itsare related
to the aircraft type and operating capabilities.
Generally tlie best aerodyt~aniicdesig~ires~~ltsin
the poorest radiating Jntenna when consiclering
only ungroi~ndedantennas. and care must be
taken here
in order not to dcgratle the systen?
operation.
The antenna coupler locatioti ~fictatcsthe location
of one end of the atiterinn.
Thc oi~tp~~tof the
coupler is the beg~nning ut' [Izc antenna and the
antenna wire inside thc aircraft rni~stbe restrict-
ed

The antenna radiation cllaractrristics
