External High Gain Antenna Specifications

How to purchase a high gain antenna including options and specs

Wattwatchers Auditor 4G devices are supplied with a "stubby" antenna that fits directly onto the device. This antenna is generally adequate for most situations as our devices choose the best of any of the available mobile communications networks.

However, in some situations, an external antenna may be required. See our article Do I need to fit an external antenna for more information.

How to purchase a high-gain antenna or 15m extension

When do I need a high-gain antenna?

If you are getting a "Low Signal" or "Poor Signal" warning in Onboarding, or the Auditor's L3 light is off or flashing this means the Auditor is in a position with poor 4G and will require an external antenna to replace the right-angle "stubby" antenna. 

See our article Do I need to fit an external antenna for more information.

Why is my signal quality poor?

For some extreme cases, such as in very low signal environments and remote locations, an external high gain or specialised antenna may be required to establish a reliable connection to the network. External high-gain antennas allow installation outside the switchboard or electrical switchroom and boost the signal strength depending on the network and antenna characteristics.

What type of high-gain antenna do you supply?

We supply a CSM550 3G/4G/5G Compact High Gain Antenna

Extending External Antennas

We supply a 15m extension coaxial cable for our high-gain antenna

In some situations, the antenna may need to be installed some distance from the Auditor device so it can be placed in a location with an adequate signal. For example, if a device is installed in a basement, the standard cable length may not be sufficient to reach out of the room to achieve better reception.

Wattwatchers can also supply an extension cable so that the antenna can be mounted up to 15m away from the Auditor device if required.

Can I source my own antenna?

Yes, you can source your own antenna, we provide a link for antennas that have been tested with our device but are not fully supported. Please see this article for more information.
