When you are considering which of the multiple types of two-way radios to buy, you may have heard of UHF and VHF radios. But you may not know what these acronyms tand for. The concept of UHF and VHF radios are quite simple, and choosing between the two doesn't have to be a difficult decision.
Function
UHF and VHF radios are two-way radios. UHF stands for Ultra High Frequency, and VHF stands for Very High Frequency. A two-way radio is something like walkie talkies, though there are several differences between a simple set of walkie talkies and UHF or VHF radios. The biggest of these is the range and frequencies of the three.
UHF
From 300 to 3000 Mhz (mega hertz) frequencies represent the range of UHF (Ultra High Frequency) radios. It has now become possible and easy to create and build a two-way radio with this frequency capability. Due to this, UHF radios have become more economical to buy and have come into direct competition with VHF radios. UHF are, in fact, considered to be more popular than VHF radios. UHF radios are most commonly used indoors or in areas where a lot of interference may be found, such as buildings and hills. They are known to have a smaller outdoor distance range, but are known to be able to get through steel, woodand other building materials.
VHF
VHF radios use frequencies from 30 to 300 Mhz. Remember, VHF stands for Very High Frequency. These radios work best in environments that are outdoors and with little to obstruct the signal. For these reasons, VHF radios are often used in public safety settings, such as with outdoor security and line-of-sight situations. VHF signals travel farther than UHF, but again, cannot penetrate obstructions the way UHF radios can.
Insights From Experts
If you are completely lost, or think you have the gist and want to find the two-way radio that best fits you, be sure to still talk with the professional in the equipment store before you purchase. Depending on your usage and your plans for it, the expert in the store may be able to suggest a certain brand name or additional equipment to get the optimal benefits of it.
Bottom Line
The bottom line is that which product you buy, UHF or VHF, depends greatly on your needs and plans for it. Both of these radios are great for certain purposes. It is clear that the decision cannot be made without knowing the specifics of the radios and the specifics for your plans for them. If you are going to be using it in an area with a lot of interference, a UHF radio may be best. However, if you are using these radios over a long range with little interference, a UHF is for you. The choice is up to you.
