Specifications

A low profile antenna type may be more suitable and is preferable to mounting the antenna on the side of
vehicles; particularly high sided vans.
If a whip antenna is cut to length a protective cap must be securely fitted. Do not leave a sharp,
uncovered point at the top of the rod.
2.8.2.4. Magnetic base antenna safety
The magnetic base must be of a suitable size for the antenna and vehicle operating speed. If necessary
consult the antenna manufacturer for the application data to ensure suitability.
The base
• must be directly placed on a flat area of steel
• should not have any other material inserted between the magnetic base and vehicle body other than
a protective pad or boot supplied by the antenna base manufacturer. This is to avoid reduction in the
magnetic retention strength and any effect on the coupling to the ground plane
2.8.2.5. On-glass antenna safety
On-glass antennas must be:
• securely fitted and fixed as per manufacturer’s instructions
• located such that driver visibility is not impaired
• mounted outside of the swept area of the front or rear windscreen, see Appendix H.
2.8.2.6. Antenna safety on motorcycles
When an antenna is to be installed on a motorcycle consideration should be given to the type and
position of antenna to minimise any safety hazard to the rider, pillion passenger, other road users and
pedestrians (e.g. use of a flexible whip type antenna).
2.9. Precautions when working on vehicles
If there is any doubt over safety seek expert advice.
2.9.1. Electric powered and hybrid vehicles
Caution should be exercised when working on this type of vehicle due to the presence of high energy
potentials from a large bank of batteries.
The location of the isolation switch should be noted and in the interests of safety the supply should be
isolated before work on the vehicle begins.
To ensure that any adverse effect on existing vehicle equipment is avoided advice on the correct isolation
procedure should be obtained from the vehicle manufacturer.
Note that on some hybrid vehicles utilising both an internal combustion engine and a battery-powered
motor for propulsion power cables carrying up to 500 Volts may exist. Before working on vehicles of this
type ensure that the route of high voltage cables has been identified, and if possible isolate the battery
supply. If in doubt, seek advice from the vehicle manufacturer.
2.9.2. Vehicle battery disconnection
Some electronic equipment fitted to vehicles may malfunction or require resetting when disconnected
from the power source, see section 2.9.2.1. It is therefore recommended that where possible but without
compromising safety the vehicle’s battery is not disconnected.
If the battery remains connected while installation work is carried out then adequate safety precautions
must be taken to prevent any damage to existing electrical circuits and to ensure the safety of the
installer. Note that some vehicles carry more than one battery.
Always refer to the vehicle manufacturer for guidance regarding the vehicle battery and safely working on
the vehicle.
