UHF Radios

UHF versus VHF Radios

Find out about the primary differences between UHF and VHS radios.

There are two main type of for walky talk type radios.  There is UHF, known as ultra high frequency, and VHF, which is called very high frequency.  Really, though, neither is better than the other one, it is just they both are best used for particular application.  Each frequency band is effective when used in the proper environment and use.  You need to understand how each of the radios operate best so you can decide which unit is most appropriate for you.

With UHF radios its frequency range is between three hundred and three thousand mega hertz.  Up until lately, you would not find it used very often.  But now, with the proliferation of wireless applications you see it used extensively.  Bluetooth, GPS, and WiFi are all common uses of UHF frequencies you will see today.  UHF radios have many more available channels than with VHS radios.  This means there is less of a possibility of having signal interference when it is being used.  In the city where there are many people and building the UHF signal has much better penetration than with VHF.  Also, if you are in an area where there might be interference from other radio channels then UHF is best for that situation as well.  UHF shines when it is used near barriers like walls, parking structures, or dense landscaping.  One thing to keep in mind is that if you decided to use these radios for commercial application the FCC will require you to obtain a license.  

With the VHF radios they will function between the frequencies of thirty to three hundred mega Hertz.  You will see that TV stations, two way radios, and FM radio stations will broadcast their signal in this range. VHF is vulnerable to more line of site issues, and the signal excels and at traveling across wide open spaces. The VHS signal can penetrate some barriers, it just can’t do this as well as with UHF signals. Jus to give you an idea on the power of VHF, it can travel over double the distance that UHF can. This makes the VHF radio quite suitable if you mainly work outside, and using it with a base station. VHS equipment is usually much easier to operate and maintain, however, the equipment is typically much larger compared to UHF. Because of this, you can usually purchase VHF radios much cheaper and get better deals with them. You will also see that these units will have much longer battery life compared to other radio units. This is particularly beneficial if you are using hand held devices.    

To keep this in perspective, if you are operating your radio around many obstructions, and you are not on a tight budget, then  you will want to consider using UHF radios.  If you are using your radio in wide open spaces or over long distances, and your funds are limited, then you should consider a VHF radio.  Both types of radios will work fine over short distances, and can be used as hand held devices.
