Zartek ZA-725 Professional 16-Channel UHF Two-Way Radio | 500 mW Licence-Free

Description

Zartek ZA-725 professional UHF radio for licence-free operation with a licensed higher-power option

The Zartek ZA-725 is a robust 16-channel handheld UHF radio designed for professional team communication in security, farming, factories, warehouses, hospitality, events and similar working environments. As supplied, it operates at 500 mW on preset 446 MHz and 464 MHz licence-free frequencies.

For applications where greater communication distance is required, Zartek states that the ZA-725 can be configured for higher-power 4 W licensed UHF operation. This is not a licence-free power boost: the customer must obtain the applicable ICASA radio frequency spectrum licence and the radio must be programmed to an authorised frequency.

Is This Right for You?

• Well suited to security teams, factories, warehouses, farms, hotels, events and other groups needing fast local push-to-talk communication.
• A practical choice where teams need communication without depending on mobile-network coverage or cellular airtime.
• Useful where compatible earpieces, speaker microphones, vehicle charging or external antenna options may be required later.
• If you specifically require an IP-rated waterproof radio or encrypted digital communications, choose a model designed and rated for those requirements.

How It Works

For standard licence-free use, the ZA-725 is supplied with 16 factory-programmed channels using the 446 MHz and 464 MHz licence-free frequency groups at 500 mW. Radios communicating with one another must use matching frequencies and compatible CTCSS or DCS tone settings.

If the standard configuration does not provide enough range for the application, the ZA-725 can be configured for 4 W licensed operation within its 400–470 MHz UHF hardware range. Higher transmit power can support greater practical communication distance in suitable conditions, but actual performance still depends heavily on terrain, buildings, antenna position and interference. The customer must first obtain the appropriate ICASA spectrum licence and authorised frequency; the radio’s 400–470 MHz capability does not mean every frequency in that range is available for private use.

Why Choose This Product?

• Ready for licence-free use: The factory-programmed 500 mW channels allow compatible radios to be put into service without setting up a high-power licensed radio system.
• Useful working range: Zartek estimates 600 m–1.2 km indoors, 2–6 km outdoors and 10–30 km with elevated line-of-sight. Actual range varies with the operating environment.
• Long operating time: The 1100 mAh Li-ion battery is rated at approximately 30 hours of average use on a 5:5:90 transmit, receive and standby duty cycle.
• Flexible accessory support: The 2-pin side connection supports verified Zartek earpieces, headsets, speaker microphones and the optional programming cable.
• Expandable antenna options: The detachable antenna allows compatible Zartek vehicle and fixed external antenna kits to be used where appropriate.
• Programmable operation: VOX, channel announce, call ring, emergency alarm, compander, battery indication and other programmable functions allow the radio to be adapted to different working environments.

Before You Buy

• Licence-free configuration: Standard operation is 500 mW on the factory-programmed 446 MHz and 464 MHz licence-free frequencies.
• 4 W operation requires an ICASA licence: Higher-power operation must use an appropriately licensed and authorised frequency. The customer is responsible for obtaining the applicable ICASA radio frequency spectrum licence before operating the radio in this configuration.
• Channel settings must match: Radios need matching frequency and tone settings to communicate correctly.
• CTCSS and DCS are not encryption: Tone filtering helps reduce unwanted received traffic on shared frequencies but does not make conversations secure or private.
• No published IP rating: Zartek does not specify an IP waterproof rating for the ZA-725, so the radio should be protected from significant water exposure.
• Optional equipment: Vehicle accessories, external antenna kits, programming equipment, spare batteries and specialist audio accessories are sold separately.
