Here at Radiotronics we tend to be asked this question a lot, and for good reason. Picking wrong could result in your radios not working as effectively in your business, or not even working at all. Firstly, this is what they are:
UHF – Ultra High Frequency
This is the frequency band of 440-470mHz for business-grade two way radios. This frequency band is often selected if the radios are to be used both indoors and outdoors. A UHF wavelength is smaller (about 70cm) than VHF which means it is much better at penetrating walls and obstacles. Because of this, UHF is a much more common choice than it’s VHF counterpart, for example in schools, offices, warehouses, etc. Wherever there are walls, think UHF!
VHF – Very High Frequency
This is the frequency band of 136-174mHz for two way radios. This band is often used for the outdoors only. VHF’s wavelength is much larger (around 2m) than UHF, which means it can really struggle through solid objects. However, in the outdoors, it tends to have better range than UHF in open environments, such as farming, hiking and outdoor activities.
One very important thing to know about these frequency bands are that they do not mix; UHF radios will not work with VHF radios and vice versa. These radios are manufactured so you could not add a frequency if it is not within the range.
If you have purchased licenced radios from another company in the past and are wanting to purchase more from Radiotronics, we can confirm what frequency your radios are already on before you select a band and make a purchase. You can either contact us and quote the long model number on the radio (which can be found when you remove the battery on a sticker on the radio side) or alternatively take a look at our detailed product pages which are being updated with this information.
If you have purchased radios from Radiotronics in the past, your previous invoices will confirm your frequency version.
If you are wanting to purchase a brand new fleet of radios and can’t decide which frequency band would be best for you, please give us a call and we will be more than happy to assist!
