ABSTRACT:
A dipole element insulator integrally formed of a substantially rigid, yet somewhat resilient, synthetic plastic material has opposed dipole element rod supporting arms to which inner ends of the element rods are pivotally supported to enable their swinging towards and away from a supporting boom across which the insulator is fixed, outer marginal peripheral portions of which insulator arms are formed with U-shaped through slots defining outwardly-extending U-shaped marginal arm portions the outer or base sides of which are provided with ramps leading to central locking slots operative as detents for removably retaining the respective dipole element rods in their extended positions of use.
