The Motorola radio is available in two frequency ranges:
-
VHF (Very High Frequency) — 136–174 MHz
-
UHF (Ultra High Frequency) — 403–527 MHz
The difference between VHF and UHF in the context of this radio (including with AES-256 encryption) is as follows:
🔶 1. Frequency Range
| Characteristic | VHF | UHF |
|---|---|---|
| Frequency range | 136–174 MHz | 403–527 MHz |
| Wavelength | Longer | Shorter |
| Obstacle penetration | Worse (walls and obstructions interfere more) | Better penetration through walls and buildings |
| Range in open areas | Better (up to 10–15 km in the field) | Shorter (up to 5–8 km depending on conditions) |
🔶 2. Recommended Use
| Scenario | Recommended Band |
|---|---|
| Open areas, rural zones, nature | VHF |
| Urban environments, buildings, dense infrastructure | UHF |
🔶 3. Compatibility
UHF and VHF are not compatible with each other.
If you already have other radios, it's important that they operate on the same band, otherwise they won't be able to communicate.
🔶 4. Antennas and Size
-
VHF antennas are usually longer.
-
UHF antennas are shorter and more convenient for portable use.
🔐 AES256
The AES256 (Advanced Encryption Standard) algorithm provides voice and data encryption.
It does not depend on the frequency band — it works the same on both VHF and UHF.
✅ Which One to Choose?
| Condition | Recommendation |
|---|---|
| Outdoor use, nature, long-range communication | VHF |
| Indoor use, industrial settings, city | UHF |
| Existing radios in use | Choose the same band for compatibility |
