Technical Specifications

Frequently Asked Questions

Q: What's the difference between 2 Watt and other UHF radios?

A: The UH620-2 Max delivers 2 Watts (2000mW) output - quadruple the power of standard 500mW radios, double 1W models, and 33% more than 1.5W. This translates to 13+km range versus 10+km for 1.5W, 7+km for 1W, and 3+km for 500mW. This is the absolute maximum power and range available in handheld UHF radios, providing unmatched signal penetration through obstacles and the longest-distance communication for extreme remote exploration.

Q: Is this twin pack ready to use out of the box?

A: Absolutely! The UH620-2 Max includes 2 complete radios with 6 x AA Ni-MH 1200mAh rechargeable batteries (3 per radio, pre-installed), 1 AC adaptor for mains charging, 2 USB-C cables for portable charging, plus mounting accessories. Simply charge the batteries and start communicating immediately with ultimate 13+km range.

Q: Can both radios use voice scramble together?

A: Yes! Both radios feature compatible voice scramble technology. When enabled with matching scramble codes, your communications are encrypted preventing eavesdropping from other UHF users on the same channel for private ultra-long-distance communication.

Q: What's the real-world range with 2 Watt power?

A: The 13+km specification is line-of-sight range in open terrain. Real-world performance: open fields/beaches 10-13km, light forest 5-8km, dense vegetation/urban 3-5km, mountainous valleys variable. The 2W power provides the absolute best performance available in handheld UHF radios, maintaining reliable contact in extreme-distance scenarios where all other radios fail. Duplex repeater access extends range to 50+km depending on repeater location.

Q: Does the extra power drain batteries faster?

A: While 2W transmission uses more power than lower-powered models during actual transmission, the 20+ hour rating reflects typical usage patterns (5% transmitting, 5% receiving, 90% standby). The included higher-capacity 1200mAh batteries (versus 1000mAh in lower models) help offset the increased power consumption. For extreme remote adventures requiring maximum range, the trade-off is worthwhile. Dual USB-C charging provides flexible power management.
