Two connection interfaces are combined in a single assembly for high frequency signal propagation of a GPS antenna. At least one connection interface is a constant impedance connector. The connector assembly allows for the application of o-rings and gaskets to be placed circumferentially about the radome to protect against environmental elements, mechanical shock and vibration. The first connection interface has a male plug on a first piece of a dual connector design, and a complementary female plug on a second piece. The second connection interface comprises a plug of any standard industry connector mounted on the second piece opposite the complementary female plug, and is configured to easily mate to a corresponding plug from a cable or other electronic equipment.
