Antennas

We offer a wide range of 27 MHz, 477 MHz, mobile phone and AM/FM antennas. Manufactured to exacting high standards to accessorise our range of market leading radios. Suitable for all applications whilst offering exceptional performance, reliability and value.

Two important factors when choosing an antenna are the mounting position and the desired radiating patterns for the terrain in which the antenna is to be used.
Radiating patterns

It is important to understand the relation of an antenna’s gain to its radiating pattern, as shown below. As the electrical design of the antenna is modified to increase the gain, the omnidirectional pattern is squashed in a vertical plane and is enhanced in a horizontal plane. This expands the signal’s coverage. A high gain antenna will therefore give increased coverage on flat terrain but the elevation will be limited making it unsuitable in mountainous regions.
Mounting Postions
An antenna needs a large uniform metal surface beneath the radiating elements to perform correctly. This is referred to as a ‘ground plane’. Therefore the best position to install an antenna is in the centre of a metal roof, however, this is not always possible and installation on a bull bar or mirror mount is often necessary. In this case a ‘ground independent’ antenna should be used to give the antenna its desired radiating pattern without a metal ground plane.

Radiating pattern on a flat
metal surface

The direction of a ‘non ground independent’ antenna radiation pattern varies with the vehicle mounting position as shown below.

Rear Strongest to the front,
weak to the rear.
Left Strongest to the right,
weaker to the left
(antenna right – vice versa).
Centre All directions equal (best).
Antenna Construction

Below are two examples of the electrical construction
of antennas. High gain antennas (typical 8 to 9 dBi)
are usually longer than lower gain antennas (typical
6 to 7 dBi).

 

The Antenna to suit the Terrain

Lower gain antennas are more suited
for hilly terrain where reception does not
depend on the angle of the antenna, as
shown right.

 

 

 

 
 

 

 

AE4700 Series*

The AE4700 series is the most diverse and adaptable range of large vehicle mount antennas on the market today. Engineered with the coaxial termination protected inside the spring assembly and easy
screw down fit of the whip, the antenna can easily be changed
It is now becoming more common in the radio industry for dBi to be used when rating antennas. To covert the dBi to dBd the following formula can be used dBd = dBi – 2.15.
for different gain and lengths to suit operating conditions. This is beneficial when travelling from flatter open plains where a two metre, high gain antenna is needed compared to driving in the city where a lower gain, shorter length is required. Ground independent Also available in grey Also available in white New Zealand versions available Interchange whips without changing the AE4705/6 spring base. *Patent No. 776598

Any of the whips in the AE4700 range can be effortlessly
interchanged without changing the AE4705/6 spring base. The AE4401, AE409L and AE4013 will
also fit onto the spring base, this offers
an alternative to thicker radomes.

dBi – dBd Comparison

 

There are a number of different ways an antennas gain can be rated, the most common two are dBi and dBd. dBi is the amount of gain of an antenna with respect to an isotropic radiator where as dBd refers to the antenna gain with respect to a dipole.

It is now becoming more common in the radio industry for dBi to be used when rating antennas. To covert the dBi to dBd the following formula can be used dBd = dBi – 2.15.
