1 Introduction
The OMNI-A0092 is a high power wide band jamming antenna intended for use in the 1-30
MHz frequency range. The antenna is equipped with an efficient matching unit which
provides excellent VSWR characteristics across the band with maximal efficiency.
The antenna is designed to be mounted on the roof of a vehicle or shelter and deploys
pneumatically in a fully automatic fashion in a very short period of time, requiring only two
people to deploy. When stowed, the low profile of the antenna system and its enclosure
provides for covert tactical operation.

diagram overleaf. This block diagram also illustrates the interconnections between the
components.
The following items must be secured to the roof of the container or mounting structure.
The main antenna assembly
The winch
The guy rope restraining anchors
Care must be taken with the quality of installation of the components on the roof because
personnel will be working on top of the container to deploy and retract the antenna. The items
must be mounted securely and positioned judicially to ensure the safest possible
configuration.
Incorrect, or inadequate installation could result in damage to the
antenna, and injury or death to the personnel operating the antenna.
The following items can be placed at the discretion of the installer or operator, but should be
located in a cool, well ventilated, under cover area as they are not weatherproof.
Compressor Unit
oConnected via pneumatic hose to the main antenna assembly
Remote control for compressor unit
oConnected via electrical cable to the compressor
MISC- A00052 RF Load
oThis load is used as part of the AMU, and needs to be connected to the AMU
via a length of RF cable (supplied). It is essential for the correct operation of
the antenna.

2.1 Items to be secured to the roof of the container
The OMNI-A0092 system has been designed to be roof-mounted on a container, shelter,
vehicle or the like. For the purposes of this document, installation on a container has been
illustrated, but the same principles apply to all installation types.
The items shown in Figure 3 are roof-mounted. These items must be bolted firmly to the roof
of the container.
The main antenna assembly must be bolted to the roof of the container in 40 places.
The winch is used to raise the antenna mast to the vertical position and is a heavily loaded
item (up to 500kg of pulling load can be expected). The high pulling load on the winch must
be catered for in the design of the attachment of the winch to the roof of the container.
Anchors for attaching ropes (three places) must be bolted to the roof of the container or
mounting surface. These anchor points form part of the guy rope restraining system for the
mast when it is upright.

2.1.1.1 Mounting
The main antenna assembly must be bolted down by its base plate. This is a 8mm thick plate
that flanges out at the base of the enclosure. 40 bolt holes of 8.5mm diameter are provided
around the perimeter of the enclosure. The bolt holes are all equi-spaced 250mm apart with
the corner holes spaced 45mm apart in the x- and y-direction. The bolt holes are all
symmetrically arranged.

2.1.1.2 Fasteners
M8 Stainless steel bolts are recommended for bolting down the unit. The length is to be
determined by the nature of the mounting platform, so the fasteners have not been provided
with the antenna. Mild steel bolts are not recommended due to the high likelihood of
corrosion.
2.1.1.3 Location and Orientation
The „back‟ of the main antenna assembly is defined as the end whose face has the antenna
nameplate and hazard stickers located. On a vehicle, this typically corresponds to the back
of the vehicle. The front of the main antenna assembly corresponds to the end closest to which
the winch must be located.
When selection a mounting location, it is therefore necessary to ensure there will be sufficient
space at the front of the main antenna assembly to find a place to mount the winch. As shown
in Figure 3, the back of the main antenna assembly can be mounted flush with the back of the
mounting platform.
Also take note that space (no less than 0.5m is recommended) to the sides of the main antenna
assembly is necessary, to provide a location for the guy rope anchoring brackets.
2.1.1.4 Lifting of the main antenna assembly
The main antenna assembly is a large and heavy unit that needs special care when being
handled. The unit is 4114mm long, 614mm wide and 500mm high. The unit weighs 350kg.
The unit must under no circumstances be mechanically hoisted by its
handles. The handles are not rugged enough for mechanised
hoisting. (See 2.1.1.4.1 for lifting by hand)
2.1.1.4.1 Lifting the unit by hand
Lifting the unit by hand is only recommended to a maximum of table height, for short
distances and manoeuvring the unit in place.
A total of 8 handles are provided (4 on each side of the unit). The unit must under no
circumstances be mechanically hoisted by its handles. The handles are not rugged enough for
mechanised hoisting.
Moving the unit by hand requires a minimum of 8 able bodied individuals.
For lifting by hand the weight of the unit must be distributed across the 8 handles. This means
that 8 people must carry the unit with each person taking his share of the weight at each
handle.

2.1.1.4.2 Mechanically hoisting the unit
Four hard points for hoisting have been provided. These hard points come in the form of eye
bolts situated inside the enclosure at either end in the corners. The first pair is located near the
front of the unit, on top of the steel bracket securing the sprung rollers. The second pair is
located inside the enclosure mounted directly to the base plate on either side of the securing
clamp.
Figure 5: Top view of main antenna assembly
It is recommended that a sling be used for lifting. The recommended slinging angle is 45°.
Special care should be taken using the sling with the eye bolts at the rear hard points to ensure
the sling does not interfere with and damage the top parts of the antenna. Rigging should be
performed by an experienced rigger. Installation via either a crane or forklift using the sling is

possible.
2.1.1.5 RF Installation
The main antenna assembly houses the antenna matching unit (AMU). There are four N-
connector ports on the AMU. The RF installation of the load is covered later in section 2.2.2.2
and utilises one of the ports on the AMU.
The port on the AMU which feeds the OMNI-A0092 is labelled „TO: TRANSMITTER
(MONOCONE)‟. RF cable is provided to connect the antenna to the transmitter. The cable is
to be routed through the provided hole in the base plate of the main antenna assembly. The
cable should not be pinched or over-bent during installation.
An auxiliary port is also provided on the AMU to interface to an auxiliary antenna. The port
labelled „TO: TRANSMITTER (AUX ANTENNA)‟ can be connected via the provided length
of RF cable to the transmitter. Cable leading to the auxiliary antenna from the provided port
on the top lid of the AMU is not provided.
Should the provided RF cable not be of sufficient length or become damaged, they can be
replaced with new or longer cable of similar power handling capacity, close to at least 1.5kW
up to 30MHz for the cable used to power up the OMNI-A0092 antenna, and an adequate
power handling to manage the power to be transmitted to the auxiliary antenna.
A total of three RF cables as well as a pneumatic hose (see section 2.2.1.1) are eventually to
be routed through the fairly small hole in the base plate of the main antenna assembly. The
hole has been kept purposefully small to reduce the probability of water and dust ingress and
to ease the installation of sealant once the cables have been routed. As such, the RF cables
must be fed through the hole one at a time to ensure that the connectors can clear the hole
once some cables have already been fitted. The pneumatic hose should be fitted through the
hole last. The RF cables should be secured to the base plate using the P-clips provided and the
hole in the base plate should finally be sealed once the antenna system has been tested.

2.1.2.1 Mounting
NB! The winch must be attached securely to the mounting surface. A structural evaluation of
the structure/attachment mechanics is recommended to ensure an adequate margin of safety.
To hoist the mast a load of 500kg can be expected.
The winch is used to hoist the mast out of its enclosure.
NB! Safety issues
With the winch positioned at the edge of the mounting structure, care must be taken
during winching so that the operator does not fall from the container.

2.1.2.2 Location and orientation
The winch must be mounted on the centreline of the container.
The winch must be positioned as far as possible from the antenna.
The drum side of the winch must face the antenna.
2.1.2.3 Fasteners
M12 High Strength fasteners are recommended for bolting down the winch.
2.1.2.4 Connecting the winch to the antenna
The winch must be connected via the provided steel D-shackle to the second hole on the end
of the gin pole of the main antenna assembly. The gin pole is secured via a hinged joint to the
hinge plate of the antenna assembly and via a permanently installed length of rope running
from the top hole of the gin pole to a collar at the top of the bottom mast section.
The antenna has been designed to allow the rope connection from the winch to the antenna to
be permanent, so the main antenna assembly enclosure has been provided with a notch to
allow the cable to remain in place when the enclosure lids are closed and secured. This allows
for a more rapid deployment of the antenna, as well as ensuring the winch does not get used
for tasks it was not intended. As such, the rope leading from the winch can be secured to the
antenna during initial antenna installation and allowed to remain there throughout the
antenna‟s operational life time.

2.1.3 Guy rope anchoring brackets
After the antenna is winched up it must be restrained by means of guy ropes before the mast is
pneumatically extended. Three guy ropes are employed. Two guy ropes steady the mast
laterally and one guy rope steadies the mast on the winch side towards the front.
In case of windy conditions high loads can be expected at the anchor points.
The anchors must therefore be securely attached to the mounting structure. A structural
evaluation of the roof structure/attachment mechanics is recommended.
Figure 7: Anchor fitting
2.1.3.1 Location
The two laterally positioned fittings (one on each side of the mast) must be mounted in line
with the mast when it is in the upright position. The fittings must be positioned as close as is
practically possible to the edge of the container.
The third fitting must be positioned next to the winch. Take care not to position the fitting to
close to the winch thus interfering with the winding lever.
2.1.3.2 Fasteners
The anchor fittings have 8.5mm holes for mounting. M8 bolts are recommended for
attachment of the anchor fittings.

2.2.1.1 Installation of pressure hose
The pressure hose used to actuate the mast is pre-installed on the main antenna assembly. The
hose should be routed through the hole in the base plate provided near the AMU and to the
compressor, where it should be attached to the air pressure nozzle. Care should be taken to
ensure that the hose is not pinched.
2.2.1.2 Installation of power to compressor

2.2.2.1.2 19” Rack mounting
The load has also been designed to fit a standard 19" racking system in which case the
detachable lower feet must be removed if the unit is mounted directly above other equipment
in the rack.
2.2.2.1.3 Other mounting options.
The feet on the back and bottom are screwed into mounting hard points. Brackets can be
designed to bolt to these hard points to facilitate other mounting configurations.
2.2.2.1.4 Mounting Considerations
The unit has two cooling fans that suck cooling air from the rear of the unit and blow it out
the sides. The installation must not obstruct the flow of cooling air.
2.2.2.2 RF installation
The load must be connected to the main antenna assembly AMU via a length of RF cable
(provided). The length of RF cable runs from the port on the AMU labelled „TO:
MATCHING LOAD‟ to the N-connector on the back of the RF load. The cable must be
routed through the hole on the base plate of the main antenna assembly and should not be
subjected to over-bending and pinching during installation.
The antenna should never be used at frequencies below 7 MHz if the
load is not attached. The load is necessary to provide adequate
antenna VSWR.
If a replacement or longer RF cable is required, then be sure to make use of cable rated for at
least 1.5kW power handling capacity up to 30MHz.
2.2.2.3 Powering up the load
The load must be powered up with 220 V AC via the IEC socket located at the back of the
unit. Power is required to run the cooling fans which are essential if the antenna is to operate
at full power for an extended period of time.
2.2.2.4 Alarm signal setup
The alarm status of the load can be determined from the ports of the multipin connector
located at the back of the unit.
There are 4 pins emerging from the connector, labelled „A‟, „B‟, „C‟ and „D‟. The labels are
embossed on the face of the connector.
The alarm states are described in the table below.
