Taking Australian technology to the world

ZCG Scalar has successfully carved out a specialist niche in both the domestic and export markets.

Antenna manufacturer ZCG Scalar was founded at Lindenow in Gippsland, Victoria, in 1970 by Gregor Cox, a ham radio enthusiast with the call sign VK3ZCG. Cox had identified a gap in the market for amateur radio antennas, but the business soon expanded its scope, supplying users such as the police force and emergency services, and essentially anyone else in the region who needed an antenna.

The business was bought by Garry and Sally Kelly in the mid-2000s. At that stage it still had a heavy focus on mobile antennas for land and marine vehicles, but Garry’s experience with broadcast and base stations meant that the company started getting a lot of work from the broadcasters. Although the business today still has a niche within the mobile antenna market, it is no longer reliant on it, having long since broadened is remit to cover broadcast television and radio, telcos, marine, backhaul, military users and other sectors.

Lindenow is located near Bairnsdale, about three hours’ drive from Melbourne. “It’s rural — if you came down here, we’re in the middle of Victoria’s veggie bowl,” said Trevor Small, ZCG Scalar’s general manager. “One of the reasons we’re here is that we get ‘clean air’ for antenna design and development and testing. We don’t get radio interference.

“Our test range fires out over 100 acres of vacant land,” he added. “We can spin the antennas and see what they do on a 360.”

As well as the manufacturing base and head office in Lindenow, the company has warehousing and sales offices in Perth and Brisbane. It also has a technical services division at Lindenow, responsible for research and development, site coverage predictions and radiation exposure testing.

Despite its rural location, the company has built up an enviable reputation in the export market. “We’re certainly not exporting our mobile antennas; the market’s so flooded with cheap Chinese [antennas],” said Small. “But our specialised antennas are being used in South-East Asia, and we send products to Africa, Afghanistan and many other countries. Some of it gets used for military purposes, but it also gets used for mining communications, transportation fleets, tracking, taxi fleets and so on.”

Closer to home, Small said the company sells a lot of antennas into the agricultural sector, for instance for telemetry in vineyards. Vineyards are very sophisticated these days, with moisture sensors in the ground, taps that need to be turned on and off at certain times and so on. Data and commands are collected and sent wirelessly.

An unusual job was contributing antenna technology to a radio device that can counter the kind of improvised explosive devices found in hotspots such as Afghanistan. The two variants — Greengum for soldiers and Greygum for fitting to light vehicles — are seeing service on the frontline.

According to Small, one of the biggest constraints on antennas in this day and age is transportation. “Long, thin tubes are expensive and difficult to transport, so we’re always looking at how to make [our antennas] more compact for shipping,” he said.

When asked about where ZCG Scalar sits in the market, Small said, “We’re big enough to handle high-volume builds, but we’re small enough to do custom builds and do flexible designs for customers’ particular needs.

“A lot of companies can’t do that,” he added. “They’ll do it if you’re going to order 10,000, but if you don’t need 10,000 then [they’re not interested].

“[For instance] we did a custom antenna for a US warship. They needed it to ‘fit here’, and they needed it ‘this long’, and ‘this particular bandwidth’… and it bolted straight in, so they were pretty happy,” he said. “We’ve [also] made some prototypes for the ANZAC frigates. That’s the sort of thing we’re capable of, and that’s where ZCG’s niche is.”

“We have one customer who wanted an antenna that was just pretty much bulletproof, to put on the survey buoys that are around the top of Australia for tsunami warning and surveillance and tracking,” said Small. “And he said, ‘I can’t afford to have it fail. I’ve got a 50-nautical-mile journey out there in a boat, so I need an antenna that’s really bulletproof [and] I need a custom mount to fit on the buoys. Can you help me out?’ Two weeks later we had a design for him, and he said ‘You beauty!’ He said no-one else was going to be able to do that for him.

“We get a lot of those kinds of requests, and in most cases we can help them out.”

ZCG assisting in keeping troops safe from I.E.D. threats

ZCG supply antennas to protect soldiers from the on-going threat from I.E.D.S.

ZCG along with other Australian based industries were one of many collaborative partners in a new technological advancement titled ‘REDWING’ in a life-saving, Improvised Explosive Device (IED) protection system. In a first-of-its-kind technological protection upgrade, ZCG antennas have been implemented in both personnel mounted and vehicle mounted IED protection.

Two systems have been developed to counter radio controlled IEDs: GREENGUM (for use by dismounted elements) and GREYGUM (for fitting to light vehicles).

The Defences ‘REDWING’ program was initiated to find a low-cost, robust yet lightweight force protection system for soldiers/vehicles in high IED conflict zones around the world. The new technology titled Greengum (for dismounted personnel mounted units) and Greygum (for light vehicles) is designed for use by Police or military forces in high IED threat locations.

The Greengum and Greygum systems are currently being utilised by the Afghan National Defence and Security Forces in the current conflict season, their first without significant coalition support. The design and manufacture of the Greengum and Greygum systems allows for minimal operator training and limited logistic support.

The $50 million investment by the Australian government will ensure both safety to troops and civilians as well as a domestic investment into creating local employment for Australia.

Close collaboration between all of the Australian industries evolved, led to an accelerated production schedule which led to implementation for the Afghanistan defence forces within 5 months of the pre-production design.

ZCG are an Australian based antenna and RF solutions company based in East Gippsland Victoria. ZCG has collaborated with other Australian Industries to produce high quality RF solutions and our technical RF knowledge on time and on budget, to ensure the safety of troops in conflict zones.

ZCG Scalar antennas used for railway level crossing warning system trial

In an Australian first, Lindenow company ZCG Scalar is part of an innovative railway level crossing warning system trial that can prevent collisions between trains and road vehicles.

The “Road Break-in” collision warning system warns drivers of approaching trains at level crossings and is a new level crossing safety system.

During a trial of the system late last week, Minister for Public Transport and Roads, Terry Mulder said the Radio Break-in system broadcasts messages to local vehicles to warn them of the hazards, such as approaching trains at railway level crossings up to one kilometre away.

Directors of ZCG Scalar, Sally-ann and Garry Kelly said the company was proud to be involved with the trial that has the potential to save lives.

The only Victorian company involved in the trial, Sally said it would be of great benefit to the area if the system was rolled out.

“The system also has other possible applications such as warning drivers of approaching emergency vehicles such as Ambulances,” Sally said.

Mr Mulder said in Victoria between 2001 and 2009 there were 120 people killed and 172 injured in vehicle crashes involving collisions with trains at level crossings.

“If this system has the ability to reduce the amount of people killed or injured, that is a great benefit to everyone,” Sally said.

A receiver is fitted to the road vehicle and an audible warning message is played through the vehicle’s speakers regardless of whether the radio is switched off, or set to other inputs such as an MP3 player or CD.

The NFA system installed into a trial vehicle. This system sends an audible system warning the occupants of the oncoming train.

“This innovative approach captures the driver’s attention before the vehicle reaches the railway level crossing and ensures early driver awareness of an approaching train,” Sally said.

The trial is an initiative of Brisbane based company NFA Innovations in conjuction with VicRoads and the State Government, which requested that a Victorian company supplies the antennas.

ZCG Scalar said it developed a range of antennas specific to the trial, they had to be frequency specific and something that worked with NFA Innovation’s system.

With around 1,300 level rail crossings in Victoria, Sally said if rolled out, this would be one of the biggest projects the company had been involved in and would ensure ongoing employment for people in Gippsland.
