A6M External High Gain Antennas

Cellular external high gain antenna options for Wattwatchers Auditor devices in very low signal and remote locations

Wattwatchers Auditor 6M cellular devices are supplied with a right angle "stubby" antenna that fits directly onto the front of the device. This antenna is generally adequate for most situations, as our devices automatically choose the best of any of the available mobile communications networks.

Wattwatchers can also supply an external antenna for situations where the signal strength is particularly low inside the switchboard enclosure, but adequate in the general installation location.

The Wattwatchers external antenna is not a high gain antenna and does not boost the signal performance more than the stubby antenna. It is intended to capture the available signal outside of a switchboard enclosure and is then connected to the antenna port on the Auditor device.

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

Antennas connected to an A6M require an SMA male connector and 50Ω nominal impedance.

The following 3rd party 3G/4G high gain antennas have been evaluated in Australia with the Wattwatchers Auditor 6M, but are not officially supported. 

Please consider your specific use case, local network and installation requirements before selecting and testing any unsupported 3rd party antenna.
