USB-C Fast Charging - Modern USB-C charging ports on both radios provide convenient, faster charging with widely available cables and power sources. Compatible with rechargeable AAA batteries for eco-friendly operation (rechargeable batteries sold separately).
80 UHF Channels - Full 80-channel UHF CB band coverage provides maximum flexibility for communication, channel selection to avoid interference, and compatibility with other UHF users across Australian frequencies.
3+km Communication Range - Typical line-of-sight range exceeds 3 kilometres in open terrain, providing reliable communication for outdoor adventures, bush walks, camping groups, and remote property use where mobile coverage is unavailable.
20+ Hour Operating Time - Extended battery life delivers over 20 hours continuous operation per radio based on typical usage (5% transmitting, 5% receiving, 90% standby) with alkaline batteries, ensuring all-day adventures without battery anxiety.
D+Booster Technology - Extreme Distance Booster technology enhances transmission range and reception sensitivity beyond standard UHF performance, maximizing communication distance in challenging terrain and dense vegetation.
Range Extender Duplex Capability - Compatible with UHF repeater stations for dramatically extended communication range beyond line-of-sight limitations, enabling coverage across valleys, mountains, and vast distances depending on repeater location.
VOX Hands-Free Operation - Voice-activated transmission (VOX) enables hands-free communication without pressing PTT button, perfect for activities requiring both hands like climbing, cycling, driving, or carrying equipment.

Frequently Asked Questions
Q: Is this twin pack ready to use out of the box?
A: Almost! The UH45-2 Max includes 2 complete radios with all accessories (USB-C cables, belt clips, lanyards) for immediate 2-way communication. You only need to purchase 6 x AAA batteries total (3 per radio) - either rechargeable or alkaline. Insert batteries, turn on both radios to the same channel, and start communicating immediately.
Q: What's the difference between this and buying two single UH45 Max radios?
A: The UH45-2 Max twin pack includes 2 radios in matching Camouflage Grey colour with complete accessories for both units (2 USB-C cables, 2 belt clips, 2 lanyards). It's more cost-effective than buying two singles and ensures you have a matched set ready for 2-way communication right away.
Q: Can I add more radios to communicate with more people?
A: Yes! All Uniden UH45 series radios (and any UHF CB radio from any brand) can communicate with each other when set to the same channel and CTCSS code. You can purchase additional UH45 Max singles or twin packs to expand your group communication network to as many users as needed.
Q: Will the Kid-Zone Plus work between these two radios and other UH45 radios?
A: Yes! Set all your UH45 radios to the same channel and the same CTCSS privacy code to enable Kid-Zone Plus filtering. All radios with matching codes will communicate with each other while blocking transmissions from other users on the same channel without your privacy code.
Q: Do I need rechargeable batteries or can I use regular ones?
A: Both work! Each radio accepts 3 x AAA alkaline batteries (standard non-rechargeable) for convenience, or 3 x AAA rechargeable batteries for USB-C charging capability. USB-C charging ONLY works with rechargeable batteries - never attempt to charge alkaline batteries. For best value and environmental benefit, use rechargeable batteries (sold separately).
