Short Answer
VHF stands for Very High Frequency and roughly covers the range of 30 to 300 MHz. UHF stands for Ultra High Frequency and roughly ranges from 300 MHz to 3 GHz. In professional radio, both ranges are utilized. VHF may have advantages in open terrain and at greater distances, while UHF is widely adopted due to shorter antennas and often better suitability in buildings, areas, and urban environments. The appropriate variant depends on frequency allocation, environment, antennas, buildings, range, and system.
Choosing between VHF or UHF is not merely a product option. The choice affects antennas, range, building penetration, channel planning, licensing, and accessories.
VHF and UHF Comparison
| Criterion | VHF | UHF |
|---|---|---|
| Frequency Range | Approximately 30 to 300 MHz. | Approximately 300 MHz to 3 GHz. |
| Antennas | Longer for comparable designs. | Shorter and often more practical for handheld devices. |
| Terrain | Can be advantageous in open areas. | Strong in areas, buildings, and urban usage. |
| Buildings | Project-dependent, not universally better. | Commonly used for building and business radio. |
| Decision | Always check based on location, frequency allocation, measurement, and system requirements. | |
What Does This Mean in Practice?
A VHF device is not automatically stronger in range, and a UHF device is not automatically better in buildings. Key factors include antenna, mounting height, transmission power, attenuation, interferences, repeaters, building structure, and permitted frequency use.
Common Mistakes
- Selecting VHF or UHF based solely on hearsay.
- Confusing frequency band with guaranteed range.
- Failing to consider antenna length, accessories, and vehicle installation.
- Purchasing devices before frequency allocation and measurement are clarified.
FAQ
What does VHF CH mean?
In the product context, VHF CH usually refers to a VHF version or channel configuration for the Swiss market or Swiss requirements. The exact meaning depends on the manufacturer and project.
Is VHF better than UHF?
Not universally. VHF and UHF have different propagation characteristics. The better choice depends on the place of use.
Which VHF frequencies are used in Switzerland?
This depends on the radio service and frequency allocation. The binding framework is the National Frequency Allocation Plan of BAKOM.
Which UHF frequencies are used in Switzerland?
UHF encompasses many applications, including business radio, security radio, PMR446, mobile communication segments, and other radio services. Permitted use must be checked specifically.
