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.
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 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.
