When HF radio is used. a limited amount of communication is accomplished in a direct line. Some radio waves
will travel outward from the transmit antenna along the ground (ground wave propagation) but these waves soon
lose their strength and are eventually lost. The greater use of HF radio is via Skywave Propagation which, simp|y
stated, is a process of using the ionosphere to bend the radio waves back to earth to arrive at the distant station.
To be successful in using the ionosphere in this manner you must:
a) Have a general knowledge of the ionosphere and its effect on radio waves,
b) Select the proper frequency to work in conjunction with the condition of the
ionosphere.
c) Ensure the angle of radiation of the radio waves is correct for the condition ot
the ionosphere and the distance to the receiving station.
Proper frequency selection is critical toreffective communication. To select the proper frequency. consuiting any
of the available sources of such information as ‘IONCAF' would be of great benefit. In the absence oi such
information, viable paths may be selected by receiver monitoring for calls originating near the destination of
interest or by trial and error. For example, a high frequency at night. when the ionosphere is at its weakest, would
be too strong and the signal would go completelythrough the ionosphere and out into space. Too low a frequency
during the day, when the ionosphere is the most dense. would create a situation where the signal is so weak the
ionosphere would totally absorb the radio waves and nothing would return to earth. The general rule ct thumb,
then is; higher frequencies in the day. lower frequenu’es at night.
The angle of radiation ortake-otf angle of a given antenna is also crucial to etlective communication. The distance
from where the signal exits the transmit antenna to the point at which it returns to earth depends on the angle it
enters the ionosphere. it the angle is HIGH, the distance of the signal will be SHORT. If the angle is LOW, the
distance will be FAFt. The angle ct radiation also presents another problem. Too steep an angle means the area
of interaction between radio wave and ionosphere is smaller and the danger of the radio wave going straight
through and into space increases. Check the literature of the antenna system in use to be sure the angle of
radiation or take oft angle is consistent with the distance over which you wish to communicate.
1-6 WWW
HF radio can provide reliable communication where all other means of communication tail. The key is to know
how HF skywave propagation works and to observe the basic rules for its use.
ALE Modems provide a good deal of simplification to the operational scenario. Proper selection of antennas and
Viable frequenCies must still be made at the time 01 system commissioning, but the daily routine of selecting proper
frequencies is accomplished automatically. thus allowing the radio in an ALE network to function much like a
telephone.
All of the control functions for operating the Sunair ALE Modems are built-in to the RT-9000 software. Adding
such a modem at a later date is easily facilitated. A discussion of ‘ALE' operating routines is presented later in
this manual.

Satisfactory operation of this equipment will depend upon the care and thoroughness taken during installation.
2.4.1 GENERALINSTALLATION
For installation and use with KW equipment, modems. and other peripherals. Use this manual in conjunction
with their respective operating manuals for complete installation information.
a) Carefully plan transceiver/peripherals/coupler/antenna locations. observing thefollowing
requirements before starting installation.
b) Provide best possible FlF ground for transceiver and coupler. Use flat copper strap 1"
wide, or No.6 or larger wire, and connect to ground terminal at rear oftransceiver. Leads
to ground system should be as short as possible.
0) Provide separation between coupler output and transceiver with its associated wiring.
Coupler may be mounted up to 100 feet from transceiver it R658 RF coax cable is used,
or further if R68 RF coax cable is used.
(1) Antenna lead from couplerto antenna must be insulated for at least tokv potential. The
lead should run parallel to metal fittings or other metal objects that are bonded to the
system ground. The coupler should be as close to the antenna as possible, and never
more than three (3) feet distant as this will decrease antenna efficiency.
2-2
SUNAIR INT-9000
If the transceiver is installed on a wood or fiberglass boat. approximately ten (10) to
twelve (1 2) square feet of metal surface area in contact with the water should be provided
for use as an RF ground.
If operated on DC power. check for correct polarity before applying power.
Linear amplifiers with low level drive such as used in the
HT-SOOO will oscillate it the RF power output is radiated or
conducted into the low level stages Evidence of this situation
is erratic or excessive power output This is caused by close
proximity of the coupler output and antenna to the transmitter
and/or inadequate HF grounds. Carefully following the above
procedures will prevent this from occurring.

2.5.1 GENERAL
The RT-QOOO is designed to operate into a 50 Ohm resistive antenna system with a maximum Voltage Standing
Wave Ratio (VSWR) of 2:1. When used with the CU-9125 Digital Antenna Coupler, the system will match
antennas ranging from sixteen (16) foot whips to 150 foot long wires. The ooupler will also efficiently match
nine (9) foot whip antennas at frequencies above 4 MHz.
As there are numerous types of antennas, a complete discussion is beyond the scope of this manual.
Antennas for use in the 1.6 to 30 MHz spectmm generally fall into three of the following categories:
a) Narrow Band 50 Ohm Antennas
b) Random Length Non-Resonant Antennas.
c) Broad Band 50 Ohm Antennas.
Some general DOs and DON'T: of antenna installation are:
a) The antenna should be clear of all large objects such as trees, buildings and power lines.
b) Although the CU»9125 Digital Antenna Coupler will match electrically short antennas
(i.e. those under 1/8 wavelength), such antennas are not efficient radiators. If the
installation permits, antennas over 1 /a wavelength long at the lowest operating frequency
should be used. (Antenna length generally limits system performance in vehicular
applications at frequencies below tour [4] MHz) as proper size would be inappropriate
for the vehicle.
c) When using whip antennas. the ground system actually forms part of the radiating
system. Where space permits (such as in a base station installation) a good ground
plane or radial system should be installed at the base of the antenna.
NOTE: An inadequate ground system is most often responsible for
disappointing performance when using a whip antenna.
d) In vehicular installations and marine installations in a metal hull ship, one inch (1') wide
strap or braid should be connected between the antenna coupler ground and the frame
of the vehicle. The length should be as short as possible. in an installation aboard a
wood or fiberglass boat. a ground plate with at least twelve (12) square feet in contact
with the water should be attached to the hull and a short one (1) inch wide strap should
be connected between the coupler ground post and the plate. As previously mentioned
this ground lead should be as short as possible.
2.5.2 NARROW BAND 50 OHM ANTENNAS
Typical of this type of antenna are the Doublet and the Inverted V. Both types of antennas may be assembled
from the Sunair Doublet Antenna Kit (Sunair p/n 0996240004). Their operation is efficient for only a narrow
band of frequencies within approximately 1 1/2% of their center frequency. The antenna coupler is N_u
generally required it the frequency span of the antenna is not exceeded. Both antennas exhibit somewhat
directional characteristics. The direction of maxrmum radiation is perpendicular to the antenna wire. The
inverted V antenna is particularly suitable for communication with nearby mobile stations (with vertical
antennas) since a portion of the radiation is in a vertical direction.

2.5.3 RANDOM LENGTH NON-RESONANT ANTENNAS
Whips and Iongwires are popular non-resonant antennas The whip antenna is often used in mobile, marine,
portable or semi-portable installations because it is rugged and self-supporting. The antenna impedance is
strongly dependent on the operating frequency. therefore, an antenna coupler MUST BE used to match the
antenna to the transceiver. Best radiation efficiency will be obtained if the antenna is at least 1/8 wavelength
long at the lowest operating frequency; however, this requirement does not result in a practical size antenna
for low frequency operation. Thirty-five (35) foot whip antennas offer a good compromise between practical
height and good electrical performance at low frequencies The CU-9125 Digital Antenna Coupler is designed
to efficientiy match whip antennas of sixteen (16) foot length or greater. An efficient match may also be
obtained for a nine (9) foot whip above 4 MHz. The whip's performance is greatly influenced by its ground
system. For temporary base station installations, a minimum offour (4), six (6) foot long ground rods should
be driven into the ground symmetrically placed around the antenna base. The rods should be bonded together
with heavy strap and then connected to the antenna coupler ground by another short heavy strap. If the
antenna is mounted on the roof of a building, where a short ground lead to the coupler cannot be obtained,
a minimum of four (4) symmetrically placed ground radials should be installed at the base of the antenna.
bonded together, and connected to the antenna coupler ground post. The radials should be made of number
twelve (12) gauge wire or larger and should be at least 1/4 wave long at the lowest operating frequency. The
radiation pattern is omni-directional in the horizontal plane.
The Iongwire antenna. is a popular base station antenna where a wide range of operating frequencies are
used. The antenna impedance varies greatly with frequency and. therefore, MUST BE matched to the
transceiver with an antenna coupler. The CU»9125 will efficiently match Iongwire antennas up to 150 feet in
length. The radiation pattern of the Iongwire antenna is also a function of the operating frequency. The
two (2) most popular length Iongwire antennas. 75 and 150 feet (Sunair P/Ns 0999200003 and 099210009)
exhibit excellent low frequency radiation efficiency.
2.5.4 BROADBAND 50 OHM ANTENNAS
These are generally complex. expensive antennas requiring a large area for installation. Their use is usually
limited to high performance base station installations which must operate at an extended frequency range. As
this class of antennas has approximately 50 Ohm output impedance over the rated band of frequencies, an
antenna coupler is M required,
Some common examples are:
a) Discone (a vertical antenna with an omni-directional pattern).
b) Log Periodic (a broadband antenna with a directional pattern, this antenna is often made
in a rotatable configuration).
