CB Radios

Uhf And Vhf Applications

UHF radios are the Ultra High Frequency version of two Way Radios. Many individuals suppose that using a very high frequency radio, also known as a VHF, as a significantly better signal than with UHF radios because they work over longer distances, and can deliver a very powerful signal.  That is not continually the case, and there are more radios that have as much or more of a signal. UHF radios have a shorter frequency and therefore cover a shorter distance, however they will penetrate obstacles a lot of easier than VHF. VHF works best with an unobstructed terrain, like through middle America. Sometimes though, you can not avoid obstructions, and you would like a product that may rise over them.  An example is when you are using the radios in an exceedingly tall building, or if you are near a mountain range. There are walls and floors separating you from your fellow workers, or giant peaks are in your way. VHF would not even work in this situation, and it would be a waste of time to even attempt it. However, UHF would be fine and is a much better alternative.  The shorter wavelengths for UHF radios make it easier for them to penetrate through walls and different obstructions and create a connection with the receiver.

If you are using UHF radios as hand held devices only on FRS channels, also known as the family radio service, you do not need to apply for a license. However, if you are using UHF for business purposes then you need to have a license with the FCC. All commercial uses require the user to be licensed, however it you use them for personal use then a license would not be necessary.  Hand held devices are typically used for signals that are not over 5 watts of power. If you utilize a vehicle mounted model the Car Battery will generate the power needed to run the device. Several taxi firms use these versions of UHF radios.  It’s much easier for the company to keep in touch with the driver using a two way type of radio as with UHF, than with a cell phone, particularly if they are operating within a large crowded city.  These radios are significantly easier to operate while driving, and cause less distraction than when one is using a cell phone.

UHF radios are typically a lot better for business applications than using a mobile phone, especially if the business is operated among a smaller area or within an operating plant or factory.  Most of the communications are completed inside the business compound and thus longer ranges are not as necessary, and neither is clarity of signal.   For these commercial situations UHF radios are ideal.  Usually the signal among the confines of a plant or workplace building requires that the radio signal be ready to penetrate barriers or rise over buildings.   The UHF signal is perfect for this type of application.  If distance is additionally important and you are operating in an unobstructed location then VHF is probably a better choice.  For instance, if your business operates in a very wide open area then the VHF radio would be a significantly better alternative than with UHF radios.
