2019 Automatic Tuning Mobile HF Antenna - Barrett P/N 2019-00-10
The 2019 antenna plugs directly into the “ATU” and “RF” connectors located on the
rear of the PRC-2090 docking station using the cables supplied.
Important:- PRC-2090 transceivers must have the 2019 antenna option set during
programming.
2019 Antenna to PRC-2090 Docking Station Connection Diagram
269 of 285
Mounting the Barrett 2019 Automatic Tuning Mobile HF Antenna
The Barrett 2019 antenna should be mounted in positions similar to those
illustrated in the diagrams on the following pages. Select a position free from
excessive vibration. A bracket, fabricated to withstand the forces and vibration that
can be expected during off-road driving, should be used to mount the antenna to
the vehicle. When locating the mounting position for the antenna ensure that the
antenna body, when flexing on its vibration mount, cannot come into contact with
other parts of the vehicle. The antenna should be mounted as far from surrounding
objects on the vehicle as possible.
The antenna is supplied with one middle section and one top whip section (Barrett
P/N: BCA201901), a tapered black spring (Barrett P/N: BCA201903), an antenna
installation guide and a pre-terminated 6 metre control cable to suit the Barrett
2019 antenna to transceiver. A 6 metre (Barrett P/N: BCA201904) or 10 metre
(Barrett P/N: BCA201902) extension cable for the control cable is also available.
The control cable should be routed into either the engine compartment or boot
(trunk) of the vehicle. If the joint between the antenna control cable and the
extension cable is in an exposed position, a butyl rubber self amalgamating tape
should be used to seal the joint. Do not wrap this joint if it cannot be made
completely water tight as water will collect in the joint and cause it to corrode.
A good earth (ground) to the main body of the vehicle is essential for
efficient operation of the antenna. To achieve this clean all joints to bare metal
and use copper braid earth straps if any non-metallic joints are encountered.
After mounting the main body of the antenna, screw the black base spring onto the
antenna body followed by the whip section.
Important Information
It is ESSENTIAL to maintain the minimum clearances between the antenna
and surrounding metal work as indicated in the diagrams. FAILURE TO
MAINTAIN THESE CLEARANCES WILL NOT ONLY REDUCE THE
EFFICIENCY OF THE BARRETT 2019 AUTOMATIC TUNING MOBILE HF
ANTENNA BUT MAY ALSO LEAD TO INTERNAL RF ARCING AND FAILURE.

Typical Military Vehicle Mounting Example
Caution:- Whilst the 2019 automatic tuning mobile HF antenna is designed to
withstand vibration to military specifications on tyred vehicles, some
mounting positions on large prime-movers, particularly front mounted bull
bars, are subject to vibration that far exceeds this specification. Do not mount
the 2019 antenna in positions such as these as damage to the antenna may
result.
272 of 285
Antenna Assembly
Mounting the Base Spring
The base spring should only ever be hand tightened, if a tool is used it may damage
the spring base.
273 of 285
Mounting the Whip Sections
To mount the whip section it is recommended that only one section of the whip is
screwed onto the antenna at a time. The whip section should be hand tightened fully
then a suitable tool (ie: a spanner) can be used to tighten the section a further 10 to
20 degrees clockwise while holding the antenna body with a free hand.
To mount 2 whip sections together the unattached whip section should be hand
tightened fully then a suitable tool (ie: a spanner) can be used to tighten the section
a further 10 to 20 degrees clockwise while holding the already screwed on whip
section with a free hand.

Testing the Barrett 2019 Automatic Tuning Mobile HF Antenna
To test the Barrett 2019 antenna, first select the lowest transmit frequency in the
transceiver and press the TUNE key. The display should show the word “Tuning”
for a few seconds, followed briefly by “Tune Passed” and an indication of the
measured VSWR (Voltage Standing Wave Ratio) value. Check this reading against
the VSWR meter.
Repeat the above test on the highest frequency in the transceiver and on a
selection of frequencies in between at approximately 2 MHz intervals. If the tune
passes at all times the Barrett 2019 antenna is working correctly. The Barrett 2019
antenna tunes to maximise whip current, not minimise VSWR, but the displayed
VSWR value should generally be between 1.0:1 and 2.0:1. However, if the display
shows “Autotune Fail” accompanied by low pitched beeps at any point, the Barrett
2019 antenna has failed tune. Confirm the "Antenna Type" is selected as either
"910 Mobile Antenna" or “2019 Mobile Antenna” in the transceiver Protected Menu
I/O settings field. Check all cables are correctly connected, check the earth cable
from the base of the Barrett 2019 antenna has a good connection to the vehicle
body (not chassis or battery), check the whip fitted is not faulty or incorrect and
move the vehicle if the Barrett 2019 antenna is close to any metal fences, buildings
etc. If the problem cannot be resolved, contact your dealer or Barrett Service
Department for advice.

910 Automatic Tuning Mobile Antenna - Barrett P/N BC91000
The 910 antenna plugs directly into the rear of a PRC-2090 fitted into the PRC-2090
Vehicle docking station or the PRC-2090 Base docking station transceiver using the
cables supplied. Important:- PRC-2090 transceivers must have the 910 antenna
option set during programming.
The 910 antenna should be mounted in positions similar to those illustrated in the
diagrams below. Select a position free from excessive vibration. A bracket,
fabricated to withstand the forces and vibration that can be expected during off-road
driving, should be used to mount the antenna to the vehicle. When locating the
mounting position for the antenna ensure that the antenna body, when flexing on its
vibration mount, cannot come into contact with other parts of the vehicle. The
antenna should be mounted as far from surrounding objects on the vehicle as
possible.
276 of 285
Caution:- Whilst the 910 automatic tuning mobile antenna is designed to
withstand vibration to military specifications on tyred vehicles, some
mounting positions on large prime-movers, particularly front mounted bullbars, are subject to vibration that far exceeds this specification. Do not
mount the 910 antenna in positions such as these as damage to the antenna
may result.
277 of 285
A good earth (ground) to the main body of the vehicle is essential for efficient
operation of the antenna. To achieve this clean all joints to bare metal and use
copper braid earth straps if any non-metallic joints are encountered.
After mounting the main body of the antenna, screw the black coil onto the antenna
body followed by the stainless steel whip.
Note:- Some models of the 910 antenna have a one piece spring and a stainless
steel whip in place of the coil and whip.
278 of 285
The antenna is supplied with a pre-terminated 1.5 metre cable tail. This should be
routed into either the engine compartment or boot (trunk) of the vehicle. A 6 metre
pre-terminated extension cable is supplied to connect the antenna to the
transceiver (this cable may be extended to 12 metres by use of another extension
cable). If the joint between the antenna stub cable and the extension cable is in an
exposed position, a butyl rubber self amalgamating tape should be used to seal the
joint. Do not wrap this joint if it cannot be made completely water tight as water will
collect in the joint and cause it to corrode.
To test the antenna, attach a VSWR meter in line with the coaxial cable at the
transceiver. Select any channel on the transceiver and activate PTT or use the tune
function on the transceiver. The antenna should tune (indicated by the sound of
relays clattering), within 2 seconds. Use the tune function to check the VSWR of
the antenna, it should be less than 2:1. If the tune sequence does not occur check
all wiring thoroughly and check that the transceiver is programmed for use with a
510/910 antenna. If the VSWR is not within an acceptable limit check the earth
(ground) bonding of the antenna base to the vehicle.
To secure the whip if driving under low objects or for use of the 910 in an NVIS
mode (for short range communication) secure the whip as illustrated in the diagram
below with the steel wire clip and lanyard supplied.

Overview of HF Operation
HF (High Frequency) is the radio spectrum with frequencies between 1.6 and 30
MHz. Within this radio spectrum an efficient form of transmitter modulation, SSB
(Single Side Band), is used. This, combined with the use of the ionosphere - a layer
of ionisation gases that resides between 100 and 700km above the earth’s surface,
provides efficient, cost effective communications over short, medium and long
distances - without the need for expensive re-transmission devices, such as the
VHF or UHF repeaters or satellites, all of which have on going operational costs
and a reliance on a physical infrastructure.
In many remote areas, HF/SSB is the only form of communication possible.
HF Propagation
When HF/SSB radio waves are generated by the transceiver there are usually two
components:-
The ground-wave, which travels directly from the transmitting antenna to the
receiving antenna following the contours of the earth.
The sky-wave, which travels upward and at an angle from the antenna, until
it reaches the ionosphere (an ionised layer high above the earth’s surface),
is refracted back down to earth, to the receiving antenna.
Generally speaking, ground-wave is used to communicate over shorter distances
usually less than 50km. Because ground-wave follows the contours of the earth, it
is affected by the type of terrain it passes over. Ground wave is rapidly reduced in
level when it passes over heavily forested areas or mountainous terrain.
Sky-wave is used to communicate reliably over medium to long distances up to
3,000km. Whilst the nature of sky-wave propagation means it is not affected by the
type of terrain as in ground waves it is affected by factors involving the ionosphere
as described below.
280 of 285
Radio Wave Propagation Illustrated
The following illustrations show the characteristics of ground-wave and sky-wave
propagation during day and night time. In each illustration the height of the
ionosphere above the ground is shown.
In both illustrations Station A communicates with Stations B, C and D. Propagation
from Station A to B is by ground-wave. The diagrams illustrate that the ground
wave is not affected by the time of day and the height of the ionosphere above the
ground.
Propagation from Station A to C and D, however, is by sky-wave and as the
diagrams illustrate the sky wave is significantly affected by the time of day and the
height of the ionosphere above the ground.
Under each diagram there are recommended working frequencies listed. Please
note that these will vary according to time of year and other factors. They are
intended only as a guide and are subject to change.
Day
The sun is higher, the ionosphere is higher, the best frequency to use is
higher
A to B - Possible optimum working frequency is 3 MHz
A to C - Possible optimum working frequency is between 7 - 9 MHz
A to D - Possible optimum working frequency is between 13-16 MHz
281 of 285
Night
The sun is lower, ionosphere is lower, best frequency to use is lower
A to B - Possible optimum working frequency is 3 MHz
A to C - Possible optimum working frequency is between 5 - 7 MHz
A to D - Possible optimum working frequency is between 9 -12 MHz
Factors Which Affect HF/SSB Communications
There are a number of different factors which will affect the success of your
communications via HF/SSB radio. These are outlined below:Frequency Selection
Frequency selection is perhaps the most important factor that will determine the
success of your HF/SSB communications.
Generally speaking the greater the distance over which you want to communicate,
the higher the frequency you should use.
Beacon Call, a Selcall (Selective Call) function built into the Barrett 950 transceiver,
makes finding the correct frequency to use easy. Beacon Call is based on the
network transceivers all having a selection of frequencies that will accommodate
most ionospheric conditions. When in standby the network transceivers scan these
frequencies waiting for a call (Selcall or Beacon Call) from another transceiver. The
transceiver wishing to check for the best frequency to operate on sends a Beacon
Call to the station he wishes to contact. If his call to the other station is successful
he will hear a revertive call from the station he is calling, indicating the channel he
selected was suitable for the ionospheric conditions prevailing. If he does not hear
this revertive call or it is very weak, he tries on another channel until a revertive call
of satisfactory signal strength is heard.
282 of 285
(Refer to Selcall (Selective Call) section of this manual for full details on Beacon
Call operation.)
Time of Day
As a rule, the higher the sun, the higher the frequency that should be used. This
means that you will generally use a low frequency to communicate early morning,
late afternoon and evening, but you will use a higher frequency to cover the same
distance during times when the sun is high in the sky (e.g. midday). You will need
to observe the above rule carefully if your transceiver has a limited number of
frequencies programmed into it, as you may only be able to communicate
effectively at certain times of the day.
Weather Conditions
Certain weather conditions will also affect HF/SSB communications.
Stormy
conditions will increase the background noise as a result of ‘static’ caused by
lightning. This background noise could rise to a level that will blank out the signals
you are trying to receive.
Man-made Electrical Interference
Interference of an electrical nature can be caused by overhanging power lines, high
power generators, air-conditioners, thermostats, refrigerators and vehicle engines,
when in close proximity to your antenna. The result of such interference may cause
a continuous or intermittent increase in the level of background noise.
System Configuration and Installation
The method in which your system is configured and installed will also affect the
success of your HF/SSB communications. Your choice of antenna system and
power supply is critical. Correct installation is also extremely important. An HF/SSB
transceiver is generally installed using different rules to those used to install VHF or
UHF transceivers. Failure to correctly install an HF/SSB system will greatly affect
the communications quality you will obtain. Refer to the installation section of this
manual for details.
Your local Barrett representative will be able to assist with your system
configuration and/or installation.
Special Note - HF Communications Compared with VHF or UHF Short Distance
Communications
Communications on any HF/SSB transceiver will sound different to that on a VHF
(Very High Frequency) radio or UHF (Ultra High Frequency) radio or telephone.
This is because of the nature of HF propagation and the modulation methods used.
On HF/SSB transceivers there will always be background noise evident behind the
signal you are receiving and this will increase when there is electrical interference
or thunderstorm activity in the area.
