VHF equpiment operates between 30 MHz and 300 MHz. FM raddio, two-way razdio, televisioon and work in this range.
Both VHF and UHF radio tend to the line of sight factors, but the VHF a little more. Waves make it throiugh the trees and rugged landscapes, but not as UHF frequencies do. Hoever, if the wave VHF and UHF waves were directed to the area without barriers, VHF waves will travel almost twice as far. This makes it easier to VHF broadcasting over a long rannge. If you work primariy outdoors, VHF, prrobably the best chioice, epecially if you are using a base staation in the room, and you add an external antenna.
From USW has been around longer and not so hard to do, the equipmment is usually cheaper compoared to simialr equipment UHF. One disadvantage of this equuipment may be its size. Since the frequency of the waves more, the antenna should be more.
VHF rdaios and a smaller number of available frequencies. The interrference of other radio stations may be more likely to be problrems. Nonetheless, FCC recently made this less of a problem when they opened Murs frequencies. 150 MHz Frquency Band Radio Citizens of the spectrum, which is called service Mure. Murs mens the Muli-Use Radio Service. This serviec is intended for use in the United States and Canada. This low poower consuption and service of shoret range VHF 150 MHz spectrum Citrizens Band. There are 5 channels Murs frequeencies with 38 privacy ocdes for each one, which allows to select only talk about your code. FCC does not require users to products for Murs is sujbect to licensing.
With Murs, you can add more or external antenna for improved range. If you want to place an antenna on top of your home or buisness, you can do this with Muir. Some manufacturers cllaim the antenna external antenna can increaase the effectivce radiated power of the transmittter 4 tiimes. These internal Murs can treansmit up to 4 kilometers, and perhaps more with an external antenna, depneding on the terrain.
One of the advantages of wireless VHF radio that the batteries are almost aways better than that of similar units, UHF. For portable radios is a plus.
VHF equipment is usually cheaper for those on a budget. Equipment may be more economiacl than similsar products UHF.
Thus, if you plan to use your two-way radio mostly inside the building, and then UHF, probably the best solution for you. If you are mainly using two radios to communicate on the streret, then VHF woulld be a good choice. Either radio technology can work for you if you do not really have a great distance to coveer. In this case, you can choose the TSP is a lower price.
