In one embodiment, an apparatus includes three remote radio heads (RRHs) mounted on a pole using one or more triangular brackets, each RRH connected to a corresponding antenna. Each RRH includes an electronics module, a heat sink mounted on the electronics module, and a cover attached to the heat sink. The heat sink comprises a base, a plurality of attached forward-facing fins, and a pair of backward-facing fins. Each forward-facing fin and backward-facing fin comprises a proximal end attached to the base and an opposite distal end. The proximal ends of the plurality of forward-facing fins are collinear. The distal ends of the plurality of forward-facing fins and the backward-facing fins define an arc of an ellipse.
