Uhf V/s Vhf - Which Two-way Radio Frequency Is Better? By: Today, there is an increasing demand for two way r
Today, there is an increasing demand for two way radios for communication in a limited area. There are basically two prime frequencies for the operation of two-way radios namely Ultra High Frequency (or UHF) and Very High Frequency (or VHF). In essence, nothing can be said with substance about the superiority of one over another because both have their pros and cons and are effectively used for communication in a small area. So how to decide which one is better? Let us have a look:
If you require a two way radio for use in the central parts of a prime city or a heavy industrial area, then definitely UHF is a good choice over VHF. This is because UHF has less probability of interference. You can also have good performance from VHF unless you select frequencies properly for preventing interferences from industrial area.
Suppose you have to use a two way radio in multiple cities then in that case, VHF operating on special frequencies will be the best and cost-effective selection. It is to be noted here these special frequencies also known as ‘traveling frequencies' may not be a proper choice in a situation wherein there are lots of other wireless equipments. E.g. in trade shows, exhibitions and other identical scenarios. In such situations, go for UHF technology based portable two-ways radio because there is a very minimal chance of any obstruction.
Single channel or steady frequency dependent VHF and UHF equipments in TV band are not regarded as fine choice for travelling. This is because almost all VHF and UHF TV channels are placed at one or other location and create frequency clashes. To avoid these clashes, you should use frequency-active UHF based two-ways radio.
When smaller and less-visible antennas are important e.g. when body transmitters have to be hidden, you should select UHF portable two-ways radio. UHF will be good when high-performance antennas are required for use in extended range.
VHF is best for use in vegetation areas or where it is possible for the signal to pass through the objects easily. Thus VHF is suitable for outdoor purpose but if the application demands both outdoor and indoor use, UHF based radio reigns supreme.
There are various situations where VHF based portable two-ways radio will be appropriate as compared to UHF based two way radio, and may also come at less price. At other times, UHF based two way radios will be ideal. There will always be complications in utilizing either one of the two and diverse factors have to be taken into account.
You must compare both UHF and VHF based radios and see what benefits you the most. If you cannot make the correct choice, do consult a dealer. There are many firms providing these gadgets in Australia. Two way Radio provides a wide range of quality 2 way radio sets and also offers accessories and services for the same. Customers have the option to customize and purchase their required handset through its online store.(read entire article)(posted on: 2014-02-13)
