Tait TP9355: The Ultimate Guide to New Zealand's Toughest Radio

The Tait TP9355 is a quad-mode, IP68-rated radio built for NZ conditions. Here is how it works and how MSL sets it up.

When your team's health and safety depends on clear, instant communication, you cannot afford equipment that might fail. The Tait TP9355 is engineered right here in New Zealand to handle exactly that pressure, the benchmark for durability and rock-solid performance when things get difficult.

It's a genuine workhorse, built to operate across different radio networks rather than locking you into one. This guide covers what the TP9355 actually does, how tough it really is, and how Mobile Systems gets it set up properly.

// Key Takeaways

  • The Tait TP9355 is quad-mode, supporting DMR Tier 2 conventional, DMR Tier 3 trunking, MPT1327, and analogue FM in one device.
  • It's IP68 (submersible) and IP65 (spray-proof) rated, and exceeds MIL-STD-810 C/D/E/F/G for shock, vibration and temperature extremes.
  • Built-in GPS, Man Down and Lone Worker alerts give genuine protection for staff working alone or in high-risk environments.
  • Available in black, red, yellow, hi-vis orange and hi-vis green, with blue specifically denoting intrinsically safe (IS) rated units.
  • Mobile Systems supplies the Tait TP9355 from $1,640.00, with expert programming and after-sales support included.
01 Β· Durability

Why "Tait Tough" Is More Than a Slogan

In critical communications, "tough" isn't a feature you add to a list, it's the starting point. Tait puts its radios through serious stress testing to prove their resilience, as shown in its well-known "Tait Tough" test videos.

Here's a look at that testing in action.

That demonstration is backed by real certifications. The TP9355 is IP68 rated, completely sealed against dust and submersible beyond the standard IP67 benchmark, plus IP65 rated against water jets. It also exceeds MIL-STD-810 C/D/E/F/G standards, tested against shock, vibration, extreme temperatures, humidity and drops, suited to the unpredictable conditions on any Kiwi worksite.


02 Β· Multi-Mode

Multi-Mode Flexibility That Future-Proofs Your Network

The TP9355 is genuinely quad-mode, supporting DMR Tier 2 conventional, DMR Tier 3 trunking, MPT1327 trunked networks, and analogue FM, all in one device. It can roam seamlessly between these, a real advantage for teams working across varied landscapes or collaborating with different agencies running different systems.

This multi-mode capability lets the TP9355 work on a modern DMR digital network while staying compatible with an older analogue fleet, so you can upgrade gradually rather than replacing everything at once. DMR delivers clear audio right to the limit of coverage, supports encryption to keep operational chatter private, and is more efficient with the radio spectrum than analogue.


03 Β· Safety

Advanced Safety and Tracking Features

Integrated GPS

Real-time location data monitored from a central dispatch, improving both safety and logistics.

Man Down

If the radio is tipped on its side for a set period, a possible sign of a fall, the device can automatically trigger an alarm.

Lone Worker

If a scheduled check-in is missed, the radio automatically triggers an alert.

Built-in Bluetooth

A clean, wireless connection to an earpiece or speaker mic, removing cables that can snag on machinery.

These are genuine safety features built to protect people working alone or in high-risk environments, not just a checklist item.


04 Β· Real-World Use

How NZ Industries Rely on the TP9355

For transport and logistics teams, a missed call can mean a delayed shipment or a safety breach. The TP9355's audio clarity helps instructions cut through the roar of a truck engine, and its integrated GPS gives fleet managers useful visibility of their assets.

On construction and civil works sites, constant noise, dust and rough handling are the norm, exactly where the Tait Tough build shines. The marine sector is another natural fit: for port workers, commercial fishers or boaties, exposure to salt and spray is a given, and the TP9355's sealed design offers real peace of mind.


05 Β· Colour Options

Colour Options for Your Operation

Tait TP9355 in different colour options

Beyond standard black, the TP9355 is available in hi-vis green, hi-vis orange, red and yellow, useful for colour-coding teams on a busy site or at a major event, high-visibility colours for ground crew, a distinct colour for supervisors or health and safety officers.

Worth knowing: blue-coloured TP9355 units specifically denote intrinsically safe (IS) rated radios, not simply a colour choice for a department. If your team works in hazardous atmospheres, an IS-rated radio is a genuine compliance requirement, not a visual preference. Talk to us about which colour and rating combination is right for your worksite.

Permanently engraving each radio with a company name, asset ID or department is a straightforward way to protect the investment, making a radio less appealing to thieves, easier to recover if lost, and simpler to manage across a large fleet.


06 Β· Getting It Right

Why Your Choice of Supplier Matters

Buying a mission-critical device like the TP9355 is the start of a long-term partnership, not a simple transaction. Mobile Systems provides solid advice on picking the right frequencies and matching your radios with the right accessories, a rugged headset for noisy sites, or a vehicle charger.

As a Tait dealer, Mobile Systems provides genuine after-sales service, repair and warranty support, backed by decades of local expertise with the Tait brand and its history in NZ public safety and emergency response.
