What does it mean if a product is “on back-order”?

If the item you’re looking for says “on back-order”, it means our current stock has already been purchased from our East Gippsland warehouse. Don’t worry — the item is already in production, and most back-orders are fulfilled within 15 working days if not less.

You can contact us at [email protected] or via our contact form for the latest availability updates.

Our system automatically replenishes stock of popular products, but sometimes demand temporarily exceeds supply. If this happens, our online store team can provide an estimated timeframe and may even place your order for immediate dispatch once it’s ready.

Who do I contact if my antenna has a fault or I wish to return it?

For returns, troubleshooting, or faults, please use our online shop contact form or email us directly at [email protected]. Using the form helps us keep track of your request and allows us to provide step-by-step support quickly.

Once we receive your enquiry, we’ll guide you through troubleshooting or our returns process to make it as simple as possible. Please allow 1–2 working days (Mon–Fri, excluding Victorian and Australian public holidays) for a response.

For full details, please refer to our Terms and Conditions.

What basic troubleshooting can I do if my antenna system has issues?

If your antenna system isn’t functioning properly or performance has dropped, we recommend the following initial checks:

Check the connector:

Ensure it’s secure and clean on all contact points.
Make sure no water is present inside the connector.

This is often the cause of faults, especially if the connector isn’t pre-terminated or has been re-terminated.

2. Inspect the coaxial cable:

Look for cuts, abrasions, sharp kinks, squashed areas, or heat damage (melted jacket, exposed braid, or bulging).

3. Check the coax-to-antenna connection:

Ensure there’s no strain or bulging at the base of the antenna, as tension can cause disconnection or system failure.

4. Inspect the antenna itself:

Check the spring/mount base, antenna base/ferrule, and radiating section (radome or whip) for damage, dirt, or water ingress.

5. Test antenna performance separately:

Use an SWR meter or network analyser to check performance without your device connected – Multimeters are not suitable.

6. Test your device:

Connect another antenna to confirm your device (e.g., CB radio) is functioning correctly. Electronics may be the issue due to dirt, moisture, or general wear.

If you need additional assistance or your product is under warranty, please refer to our Terms and Conditions.

How do I fit my antenna onto my vehicle, vessel, or structure?

All ZCG Scalar antennas come with an easy-to-follow installation guide, including helpful tips for maintenance — we recommend checking your antenna annually or before any major adventure.

Our antennas are designed for easy installation, with pre-terminated connectors and antennas fitted onto mounting springs or bases.

Because every vehicle, vessel, or structure is different, you may need to make minor adjustments to the installation steps, such as cable routing or antenna placement, to suit your specific setup.

Can ZCG Scalar fit my antenna onto my vehicle/vessel or structure?

ZCG Scalar does not provide installation services or on-site assistance for antennas or RF solutions. All products come with a comprehensive installation guide.

For professional installation, we recommend using an auto-electrician, 4WD specialist, or marine specialist. These experts have the tools and experience to install, test, and troubleshoot your antenna system.

You can find a list of distributors here. Please note that not all distributors offer installation services.
