Reviews indicate that the stronger the signal, the more reliable the reception at greater distances and with more obstacles. Businesses or municipalities in need of longer-range communications can boost their signal with repeaters or work using a trunking system.
Repeaters and trunking systems significantly increase the cost of radio setup versus handheld-to-handheld communication; however, they are necessary for large scale, emergency communication operations such as fire and police departments.

VHF Radios - It's very important to get this right the first time. Business walkie-talkies aren't toys and they aren't cheap, which is why it's important to order the right radio the first time.
Whether you're reviewing a set of 4 radios for your deli or a fleet of 40 for your distribution center, you'll want to spend wisely to avoid having to live with a costly mistake. In most circumstances, a UHF walkie-talkie is going to be your best bet. However, because UHF radios and VHF radios can't communicate with one another, it's important to take their differences into consideration when making a purchase.
The lowest high-band MHz includes 8 different frequencies designated by the FCC, and is often used by the general public and wireless microphone devices. For best results you typically only want to operate two to three units on this frequency. High quality audio is possible as well as smaller antenna size, down to 14 inches or less. The same 50 mW power restrictions apply.
As a result antenna length is reduced as well as radio range. Anything from a building to a human body can interfere with UHF transmissions. Dropouts and interferences are far more likely, but greater bandwidth occupation is permitted. As a result you may find a wider frequency range as well as wider range of audio signal. Typically, business services and UHF television channels 14 through 69 operate using these frequencies.
High-band UHF anything above MHz offers the least amount of disturbances and requires antennas measuring between 3 and 4 inches. You can increase the height of the antenna to increase the distance and quality of communication. The spectrum of each frequency band has a significant impact on the quality of communication. The higher the frequency, the better the in-building penetration. A good distance and works well inside buildings Lower frequencies travel further in non-obstructed environments MHZ is excellent for built-up indoor environments but does not offer great distance Better suited for outdoor professions like forestry and oil Often used by schools, warehouses, and retail stores.

The frequencies of VHF travel further if they are not disrupted by barriers. The only time you will want to use VHF is if you are outside in a wide-open space like a field.
VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication. UHF is better when using radios for indoor use like buildings or around cities. A plus to using UHF is you are less likely to be interfered by other two-way radios. The reason why UHF is better for inside use opposed to VHF is, UHF signal does a better job at reaching through wood, steel and concrete, therefore, can reach further into the building.
MHz stands for Megahertz and measures the speed of electronic devices. UHF is typically used by public safety officials like fire, police, and EMS with tv channels of UHF is used for common purposes like phones, televisions, and ham radio operators.
Casinos, security officials, warehouses, construction, manufacturing, and health care also use UHF radios to communicate to others across the building and through departments. A public safety official uses MHz frequencies between and and a 13 cm ham radio band has an MHz of to
