UHF Explained

Oct 11, †Ј Firstly, CB radio channels are synonymous with UHF radio channels in Australia. The CitizensТ Band is on the UHF range (Ultra High Frequency). TheyТre just different names for the same thing. That said, these are the most important CB radio channels to use. The UHF CB band radio service is available for public access and is authorised by the governments of Australia, New Zealand, Vanuatu and Malaysia. UHF CB provides 77 UHF channels, including 32 channels (16 output and 16 input) assigned to repeater stations.

For caravanning devotees and long-distance travellers, an ultra-high frequency citizen band UHF CB radko is an essential device. Ardio is especially true if you go hcannels the wilderness and bushland, and get all the channnels to the chsnnels Australian outback where cell phone reception is weak to totally channeos.

With a UHF CB radio, caravan owners and travellers can venture far and explore vast expanses of the outback without worrying about communication problems. If you do happen to uhhf into any trouble e.

But whzt the initial thrill of procuring your own UHF CB radio and practising your Alpha-Bravo-Charlie phonetic alphabet mastery and a couple of pretend s, what chnanels next? UHF CB is a auatralia citizen band two-way radio service using the Although the service is technically available to everyone, not all CB radio channels are allowed for use by just anyone for whatever reason.

In fact, the penalties can be pretty stiff for anyone caught misusing certain UHF radio channels. For example, people can face imprisonment or a hefty fine for the arf misuse of the legally allocated UHF emergency channel, or a few hundred dollars for minor cases. Therefore, it helps to te about CB radio channels in what type of pesticide is ddt, as well as legally restricted channels and proper UHF CB radio etiquette.

Below is information from the Australian UHF channel chart you can refer to so you know which channel you should leave your CB radio on by default for general use:.

Kenwood PKT-23 Two Way Radio

41 rows†Ј UHF 80 Channel Frequencies 3 Radio Frequencies (Talk Channels) for Two Way Radio are . Jan 21, †Ј UHF CB or citizen band radio is a 80 channel two-way radio system that uses the ЦMHz, radio spectrum for short-distance line of sight communications. The Australian Government has legislated that channels 5 & 35 on the UHF CB Band are reserved for emergency use only. Simply put, UHF CB or citizen band radio is a two-way radio system that uses the ЦMHz, radio spectrum for short-distance communications. It is divided into .

Whether you are planning a trip into the Australian outback, towing a caravan on the black top or a weekend 4WD adventurer, then a UHF Radio is an essential communications tool to have. UHF MHz radios have nearly replaced the older 27MHz CBs, mainly due to their considerable price drop over the past decade and the extended range offer by repeaters located throughout Australia. Since UHF signals generally travel in a straight line, the terrain can impact how well the signal is transmitted or received.

For example, UHF CB radios, pending on the antenna used, may perform poorly in hilly or forested areas and perform well in flat open countryside. UHF CBs can also access repeater stations that re-transmit the signals on another channel which can provide much further coverage see Repeaters for more information.

Spend the time viewing, they are well presented and informative. This covers These stations, which are usually owned by businesses, farmers and clubs, allow UHF users to use them to re-transmit their signal. The repeater, which previously collected the signal on 31 to 38 or 71 Ч 78 , then switches to its output channel 1 to 8 and 41 Ч 48 to transmit simultaneously to say another radio user on the other side of the hill. Repeater Station locations An interactive listing of all licensed Australian UHF radio repeaters, that can be searched by clicking on a location on a map, by town name or postcode, by call sign or by state.

Site users can update the current operational status, and link to maps of the repeater locations are provided. Below you will find a list of UHF Radio channel allocations. There are many channels that have been established by law including the Emergency channel 5 and the data transmission channels 22 and The new 80 channel system does not change the allocation use of these channels.

This chart is also available for download free from our online store. This channel, which is established by law, is used to call or locate another station. Voice transmissions are not allowed on these two channels 24 Ч 30 Used for conversations.

Note Channel 29 is specifically as a road channel. Press the duplex button on your radio to use any available repeaters. Telemetry Systems This technology is used for the transmission of data.

By utilising telemetry systems via UHF signals, farmers can remotely control the operation and function of various types of equipment such as electric fences, water pumps and dam levels from many kilometres away. Use a poor antenna or mount the antenna is a bad location, will greatly reduce your range and clarity. However depending on where you mount your antenna, will affect the way the antenna radiates. The best location for an antenna is in the middle of your roof however this is generally not practical.

Antenna are normally mounted the guard or bull bar. This these cases, it is essential that you A use a ground independent antenna see Ground Independent Antenna for more information , B mount the antenna away for vertical metal section like windscreen pillars etc. Following these suggestions will help minimise any affect on the radiation pattern.

As gain is increased, the radiation gets compressed into a thinner pattern and reaches out further to the side. The more gain an antenna has the thinner the pattern becomes and the further the signal can travel or reach.

However a thinner radiation pattern may prevent strong signal reception when driving through hills. The laws of physics cannot be defeated and without these characteristics there is simply no way to increase antenna gain. Various antenna manufactures use different references when declaring their gain figures. In the absence of a defined reference, some claims made in catalogues and on retail packaging by some manufacturers are just plain wrong.

When selecting an antenna be sure to make a couple of basic checks:. As discussed previously most UHF antennas require a ground plane, which means they should be mounted on top of a metal surface. The best spot in this regard would be the centre of your roof. Unfortunately for some people, this may not be a great idea because it could require drilling through the roof for installation.

Travellers also prefer to utilise their roof rack space for carrying supplies. If the roof is not on the cards, then other good locations to mount an antennal can include: the front guard or on the bull bar, which is probably the most common.

In all types of UHF antennas, feed line loss can be a constant threat in regards to performance. Bad feed lines can swallow up half or more of your transmitting power and therefore degrading reception.

Loss can be determined by length and quality of the feed lines, so the use of thicker co-axial cables over thinner ones is a much better option. Some common cable specifications, each being 50ohm impedance and the loss figures on a 30m run are listed below:. Handheld models are also popular with obvious advantages of portable, the high advances in electronic technology and their increased affordability.

There are some top end models that have a range of up to 12km with an impressive 5 watts of TX output power. As well as being lightweight, ruggedly built with waterproof construction, these CBs are no toy.

These units can be very handy for travellers in a whole range of situations. With handheld units, you have an extra level of safety and peace of mind when heading off on solo excursions away from the vehicle, or campsite for minimal cost. Some travellers have employed the hand held whilst maneuvering into a site. This is tactic utilises a hand held in the hand of the person guiding and either a second hand held or a fitted unit in the vehicle.
