PANORAMA ANTENNAS SW3-684 Range of Transit Antennas Instruction Manual
Introduction
This document is a guideline for installation of the TRNC[G] range of transit
antennas onto a vehicle roof and should be used as guidance in the context of
a well-planned installation.
It should be noted that the requirements of a specific installation may differ
from those outlined in this document, which gives best practice.
If In any doubt, advice from installation experts or the vehicle manufacturer
should be sought.
Important Safety Considerations
| Failure to carry out an adequate risk assessments, to follow relevant laws,
specifications,
and best practice, and to plan installations with expert advice in respect of
the matters
below may increase the possibility of death, serious injury or damage to
property.
---|---
| Panorama strongly recommends mounting the antenna using
appropriate stainless steel M12 cap
head bolts, nuts and washers sealed with the supplied M12 bonded sealing
washers tightened to a
torque of 6Nm along with the supplied N connector mounting nuts and washers
tightened to 5Nm.
| Electrical Safety Note
This product contains an active GPS/GNSS antenna (part number SR8-HG26-04FJ.
Rated voltage: 3-5VDC Rated current: 20mA maximum.
The supply to these devices must be provided with overcurrent protection of 1A
maximum.
Earthing-Grounding
In many installation scenarios (e.g.: where overhead lines are present) it
will be extremely important to ensure that there is a low resistance contact
between the antenna housing and the body of the vehicle.
After the roof is prepared for installation the conductivity in the contact
areas with the antenna should always be checked using an ohmmeter.
In accordance with Panorama’s recommendations above it is important that
appropriate corrosion resistant mounting hardware is utilized for installation
with washers and other ancillaries sufficient to provide and maintain the
required level of contact.
Where the antenna is to be fitted to a non-conductive panel an appropriate
conductive mounting plate and earthing cable or similar apparatus should be
employed in order to provide adequate earthing contact.
The installer should take all necessary steps to ensure that the antenna
installation and mounting hardware are fully compliant with applicable
regulations and industry best practice with respect to conductivity and
earthing.
Sealing
The antenna is supplied with a closed cell silicone rubber sealing pad
which requires a totally flat, clean and clear mounting surface of sufficient
strength and a significant amount of compression in order to provide an
adequate seal to the vehicle roof.
These factors should be taken into account when planning the installation or
alternative sealing measures should be adopted as appropriate.
If mounted using the recommended fixings, then the supplied M12 bonded seal
(Dowty) washers should be used.
If additional sealant is used, then care should be taken to select the correct
type to meet environmental durability, adequate adhesion and in particular,
compatibility with the antenna component material.
It is extremely important that any measures taken to seal the mounting bolts
do not impact upon the earthing contact they provide between the vehicle body
and the antenna.
Other Safety Considerations
The installation should always be planned to take account of any other
applicable safety concerns.
These should be established through an appropriate risk assessment exercise.
Other factors which may need to be considered are the strength of the mounting
panel and hardware in event of impact, the position of the antenna, which
should be adequately protected from any impact which may damage the antenna
and installation location, and the height of the installation which should be
compliant with the relevant regulations.
The antenna install location should be safely accessible by installation
personnel.
Planning & Preparation
Select an installation location, with the antenna sited a minimum of 1m (3’)
away from existing roof structures.
Check clearance under the panel, considering the depth required for mating
connector(s).
For cellular LTE variants (TRNC[G]-7-60-NJ), the antenna should be fitted in
the centre of a metallic (conductive) ground plane of minimum size 250mmx250mm
(10”x10”) or 600mm x 600mm (2’ x 2’) for UHF variants (e.g.: TRNC[G]-TET-NJ).
If fitting to a non-conductive panel, a ground plane plate of above minimum
dimension should be fitted to the underside of the panel.
In both these cases, the antenna must make low resistance contact with this
plate (<0.1Ω) using the mounting bolts and washers.
In some cases, it may be better to mount the antenna on a separate flange with
integrated mounting bolts, which is then welded to the roof panel.
Drilling Holes
Drill mounting and connector holes as appropriate.
The supplied drilling template (SW3-320) can be utilized as a guide if
required.
NOTE: Do NOT use a photocopy of the template as it may not be 1:1 scaled!
Clearance holes for the connectors should not exceed 24mm diameter to avoid
encroaching on the sealing area.
Clean the area around the holes, removing all burrs and swarf.
Apply a conductive corrosion resistant coating or paint to bare metal surfaces
to prevent corrosion.
Fitting
Ensure that the mounting panel is clean and flat within the antenna base
footprint area.
Place the antenna in position, check that the mounting holes are aligned,
check that the connectors have adequate clearance through the holes and are
accessible from the underside.
Fit the bolts with washers and lightly tighten, checking that the sealing pad
is compressing evenly.
Finally tighten all bolts to the recommended torque setting.
Route and Connect Coaxial Cables
Plan the cable routing to take into account the minimum bend radius for the
cable type used.
The cable should be routed to avoid running parallel to existing wiring or
fouling any moving controls or components.
Fit connector to suit both the equipment and cable to type and consider
securing to avoid coming lose in service.
Test and Commission
The comms antenna elements are d.c. grounded and will present a short circuit.
In order to test this antenna disconnect the commas cable from antenna, the
connector body to centre pin (on the cable) should measure open circuit.
Reconnect the comms cable to antenna and the connector body to centre pin (on
the cable) should measure short circuit.
With the GPS cable connected to the GPS antenna port the connector body to
centre pin should measure high resistance.
It is recommended to carry out a VSWR check, this should measure <2.5:1.
Cleaning and Maintenance
The antenna should not be cleaned with or exposed to strong base or solvent
cleaners.
The antenna should not be exposed to excessive oil and grease. Once installed
it is not recommended to remove or re-fit the antenna.
The antenna should be checked periodically for signs of damage.
