A heat dissipating hardline connector includes a first body portion configured to support a terminal pin assembly and a second body portion configured to be coupled with the first body portion. The second body portion is configured to receive a hardline cable. The second body portion includes a plurality of spaced apart annular grooves formed in an outer surface of the second body portion to define a plurality of fin portions that are spaced apart from one another along a length of the second body portion. The annular grooves and fin portions are configured to increase the surface area of the outer surface of the second body portion to provide increased heat dissipation by the second body portion.
