A wireless power line sensing device can include an external antenna port that permits connection of an external loop antenna to the wireless power line sensing device. The external loop antenna can be used in place of the integral loop antenna which can be disabled when the external loop antenna is connected. The external loop antenna can extend substantially linearly to define a non-spherical sensing field. The wireless sensing device can also include an ultracapacitor that provides power to the wireless sensing device and/or a curved solar panel that maximizes the solar input over a wide range of angles, providing power over a longer period of time compared to a flat solar panel.
