VHF or UHF: Decoding Two-Way Radio Frequencies for Business

VHF and UHF are the most common types of two-way radio frequencies businesses use for their communication needs. Each two-way radio frequency has its own strengths and weaknesses, and is better suited for particular industries.

Understanding which is better for your business will save time, money and improve productivity.

VHF (Very-High Frequency) 136MHz-174MHz

The VHF frequency works best in rural areas and outdoor applications where few obstacles will block the radio’s signal. The signal can be affected by line of sight factors such as buildings or mountains.

However, the VHF signal does have a greater range than its UHF counterpart, making it ideal for industries and businesses whose communication needs span large geographical areas, such as farmers and transportation.

VHF Two-Way Radios Work Best for the Following Industries:

• Construction
• Volunteer Firefighting
  
• Farming, Agriculture
• Transport

UHF (Ultra-High Frequency) 403MHz-470MHz

Two-way radios using the UHF frequency are recommended when the coverage area is restricted. Hotels and office building maintenance staff are the most common users of UHF two-way radios. The maximum distance they need to communicate rarely reaches more than a few hundred yards or several stories.

Clarity is the biggest benefit of UHF two-way radio systems. Wavelengths from UHF two-way radios travel faster than VHF wavelengths, creating a stronger signal quality and crisp sound.

UHF Two-Way Radios Work Best for the Following Industries:

• Hotels (Tourism and Hospitality)
  
• Property Management
  
• On-Site Security
• Hospitals
• Factories/Plant Production
• Schools and Universities

Repeater Systems

Repeater systems allow multiple radios on the same frequency to communicate over a large distance without loss of quality or signal strength.

For example, a construction company may set up a repeater at its command center to communicate with drivers across the city. The construction company could choose the less expensive route and rent space on a repeater network or trunking system, referred to as an RCC.
