There is provided, in combination, a mounting assembly for an upright pole through which at least one cable extends and an anti-theft assembly for inhibiting theft of the cable. The pole has a bottom and is supported by a foundation. The mounting assembly includes a plurality of spaced-apart couplers each having a top end configured to connect to the bottom of the pole, a bottom end configured to connect to the foundation and a breakaway point between the top and bottom ends of the couplers. The breakaway points cause the couplers to fail when the pole is impacted by a vehicle. The anti-theft assembly includes an inner sleeve shaped to extend about the cable. The sleeve is robust and tamper-resistant. The sleeve is positioned between the bottom of the pole and the foundation. According to one aspect, the sleeve has an upper end that connects to the bottom of the pole and a lower end that is spaced-apart from the foundation.
