Frequently Asked Questions
Analog Versus Digital Radios?
The main difference is in the way signals are transmitted and received. As with digital musical recordings, rather than use electrical signals resembling sound waves to deliver audio, the digital radio transmits and receives by processing sounds into patterns of numbers.
Both analogue and digital signals diminish as distance increases from a station transmitter. However, two-way digital radio offers improved audio quality at a greater range than analogue through better resistance to interference from other signals and avoiding the imperfections of transmission and reception which are typical of analogue.
Transmitting analogue radio is power-intensive, but new digital technology allows some radios to function about 40 per cent longer on a battery charge than a comparable analogue system.
How do I know what radio to use?
There are so many different factors which can affect a two-way radio transmitting and receiving. It is best to contact us, so we can establish your requirements and provide you with the optimum solution for your communication needs.
How much notice does TWHS need to organise a hire?
We can often fulfil orders the same day, but of course, the more time you give us, the more time we have to prepare your orders.
Do you receive a discount for long term hires?
Yes. If you are willing to commit to a long-term hire, we will commit to improved pricing for you. Please call us to discuss your requirements in more detail.
Will Two Way radios work indoors?
Yes, in most indoor situations UHF radios work best. UHF frequencies can penetrate concrete and steel walls and floors relatively well. In some cases, we need to install a repeater for greater penetration, but in any case, we will do everything we can to make sure you have the coverage you need.
Does TWHS have private frequencies customers can hire?
Yes, the frequencies you will be operating on will be digitally coded frequencies that are secured for your specific purpose and will not be accessible with by other users. It is required by ACMA that we know the exact location of where you will be using the hire radios for safety and security reasons.
What are the advantages of Two-way communication?
Two-way radios allow push to talk instantaneous communication. Two-way radios are used in a wide range of industries for safety, security and efficiency.
What is a Repeater?
A repeater is a device that takes a radio signal and re-transmits the signal at higher power to extend the coverage. Repeaters can be used in a vehicle or inside an office.
How far will a Two-Way Radio transmit and receive?
The distance a two-way radio will transmit and receive is dependent on the location of usage and whether there are any obstructions such as hills or buildings in between the radios. A portable two-way hand-held radio will work best with a line of sight within 2 kilometres of each other and is also dependent on the power watt of the radio. The more obstructions will reduce the range. However, this is a guide only and cannot be guaranteed. Mobile and fixed mount radio systems will increase the coverage to between 5 and 20 km depending on the terrain and the antenna. Users incorporate the use of a local repeater into their system to improve the unit-to-unit ranges.
