ZCG’s head office and manufacturing facility in Lindenow, East Gippsland, Victoria, Australia.

ZCG Scalar™ is a world class radio frequency antenna designer, manufacturer and consulting organisation that offer an integrated approach to identifying RF solutions in partnership with client needs.

The company began in 1970 as a family business and is still a family-owned business to this day. It started because of a need within the amateur radio fraternity for high quality reliable antenna systems, specifically designed to deliver long-term and trouble-free service in the worlds harshest environments for a wide range of industries.

Following strong support received in response to early antenna designs, in 1994 the owners took control of Scalar™ Antennas based in Melbourne and shifted the manufacturing equipment to Lindenow. The company name changed to ZCG Scalar™ and it was at this point we became a major commercial antenna manufacturer competing with other companies on the domestic and international stage.

In September 2004, G-Tech Communication Services Pty Ltd purchased ZCG Scalar™. With over 30 years experience in the RF industry, the current Directors Garry and Sally-Ann Kelly provide clients with a high degree of competence and extensive technical knowledge in antenna design, installation and performance optimisation.

Customer support, customised solutions as well as market demand resulted in continual growth of our product range to accommodate a diverse range of antennas, filters, multicouplers, coaxial cables, coaxial connectors and mounting hardware necessary for the ever-changing RF landscape.

ZCG’s in-house Research and development facility offers a wide range of RF services including custom RF antenna design & manufacture, RF systems consultancy and RF system prediction/reporting. Our R&D department technicians are qualified in:

Computer-based site propagation prediction
Computer-based antenna design and performance evaluation
360° radiation pattern testing
Passive Inter-modulation or P.I.M. evaluation
CAD/CAM antenna design and manufacture

Utilising state of the art testing hardware, software and testing facilities, our research and development technicians are able to design, model, prototype, mass manufacture and test custom RF systems ranging from low frequency HF systems through to high frequency mmW (millimetre wave) systems.

Our Research and development department is situated on-site, along-side our engineering and manufacturing departments within our facility located in Lindenow, Victoria, Australia. Allowing for seamless transition from prototype to market-ready RF solutions for today’s RF industry.

The moment we installed the first antenna we noticed a greater broadcast and reception range…“As the Director of one of Australia’s largest off-road communities, it has been a pleasure utilising the range of ZCG Scalar™ antenna systems on our race vehicles in the most demanding and unforgiving environments in the world.

Our experience has shown that the range of ZCG Scalar™ antennas provide reliability, quality and cost effectiveness that surpassed our expectations.

From the moment we installed the first antenna we noticed a greater broadcast and reception range compared to other higher priced units produced by other manufacturers.

We now run nothing but ZCG Scalar™ products on all our team vehicles and would highly recommend this great Australian made product to anyone looking for a superior quality vehicle antenna.”

Evan Sycamnias, Director, Team MudRhino.

Joe Bonavia, Regional Director Australasian Operations, Ikusi ANZ Pty Ltd, Vic.

Your firm is very reliable with deliveries…
“It arrived in good condition and on time…your firm is very reliable with deliveries, it is very much appreciated.”

Dave Eisenhauer, 96.3 FM Radio, Tumut, New South Wales.

Performance has been way beyond expectation…
“Just a bit of feedback for you, regarding vertical 3dB aerial recently purchased. Performance has been way beyond expectations, the coverage I am now achieving from my commercial security radio systems has improved at least 90% better coverage. I have one of your 15 element beams, connected to a 2 way phasing harness and connecting to the vertical, with outstanding results. Your Technical guys may like to know this feedback as well.”
Michael Searle Security Services, Tasmania.

We continue to be impressed by the quality and performance of your products…
“Yes, the antenna arrived yesterday and we were able to implement it 2 days prior than expected. I really thought we would be pushing it to be able to get the product in such quick time, but you were able to get it to us in half that time again!! It is very pleasing to be given such great customer service. Well done to you and your colleagues! We continue to be impressed by the quality and performance of your products. Many thanks.”
Rowan Quinn, Bureau of Meteorology, Tasmania.

Knowledgeable and helpful…
“It was a rare pleasure to deal with such a knowledgeable and helpful group of people. By exceeding my expectations in all areas you have ensured that next time I or anyone I know needs an antenna I will not hesitate to direct the business to ZCG Scalar™.”
Roger Costello, Western Australia.

Impressed with the service…
“From first contact through to a quick call from site to check on an installation detail I found the entire experience to be conducted in a clear, professional and efficient manner.

I was already impressed with the service provided when I unpacked the kit and found a well presented Handbook for the array with all relevant plots and installation data.

For me this was the icing on the cake ! It meant that I did not need to generate a documentation package to the customer; it had been done for me.

It is this attention to detail and focus on customer service that ensures Australian Small Business’s can stand apart from other competitors, congratulations and I look forward to a long and mutually beneficial relationship.”

John Horder, Mountain Electronic Services Pty Ltd, South Australia.

Quick and professional…
“Thanks also for the quick and professional service. We may be needing more from you as the weeks progress, look forward to doing business.”

Steve Caldwell, Head Tech, Jands Pty Ltd, New South Wales.
