Abstract: A cable reduces loop inductance by changing the cross-sectional shape of the conductive elements of power supply and return conductors to something other than the traditional circular cross sectional shape, e.g., to a thin generally rectangular shape. The power supply and return conductors are also controlled in placement along the length of the cable, so that mutual inductance is maximized within a given power supply circuit, and minimized between the given power supply circuit and other power supply circuits within the cable. The return power supply conductor may optionally be sized for multiple power supply circuits, which may further reduce loop inductance and reduce crosstalk noise between different power supply circuits within a common cable. The power supply and return conductors may be part of a hybrid cable used to power and communicate with plural remote radio units proximate a top of a tower.
