UHF Antennas Made Easy

The antenna is the most important piece of equipment in an RF communication system. It does not matter how powerful the transmitter or how sensitive the receiver, without a good antenna the propagation and collection of signals will suffer and hence limit the communication range.

It is also important to understand the relation of an antenna's gain to it's radiating pattern. The diagram below shows the radiating pattern of different gain antennas. As the electrical design of the antenna is modified to increase the gain, the omnidirectional pattern is squashed in a vertical plane, therefore furthering 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 country.

In the following information we will inform you on the basics of UHF antennas and which antenna to choose to suit your travelling requirements.

Hence the antenna choice for undulating and mountainous terrain is different than flat outback conditions.

Radiation Patterns of Different Db Gain Antennas

The illustrations below best demonstrate how radiation patterns differ between antennas.

Radiation Patterns

 

As you can see the lower dB gain antennas have a wide radiation pattern which is ideal for the coastal traveller in undulating terrain. The wider radiation pattern allows the RF to travel up and out of the lower areas. You can now purchase extremely efficient 4-5 dB gain antennas like the AE4018K1, AE4012K2, AE4702, AE4703, AE4705, CB5000 and many more.

The higher dB gain antennas have a flatter and longer radiation pattern which is ideal for flat or slightly undulating terrain. These antennas are generally 6-7.5 dB gain. Some of the best antennas in this category are AE4706, AE4011, Col6M, Col7M.

Extremely efficient 4-5 dB Gain Antennas are the most popular sold antennas in Australia for 4WD users. If you have any further queries regarding antenna applications please feel free to leave us a message on the olbis forum. Just click on the link in the left hand banner.

The antennas listed below comprise of the most efficient in there categories.
