Abstract: A new and improved multi-pin RF field replaceable mounting flange structure, to be mounted upon a RF hybrid assembly, comprises a predetermined arrangement of multi-pin coaxial electrical connectors integrally incorporated upon a single field replaceable mounting flange structure for enabling the connection of a plurality of coaxial cables onto a single field replaceable mounting flange structure such that the plurality of coaxial cables can be electrically connected in a more spatially efficient manner than has been previously capable of being achieved regardless of the particular number of coaxial electrical connectors being connected.

Abstract: A swingbolt hook includes a base having rear and front surfaces and extending along a base axis between first and second ends. Depending from the base is a swingbolt catch adapted for selective retaining engagement with the hook catch of a swingbolt. The swingbolt catch has base and distal ends and first and second opposed surfaces. Each of the first and second surfaces extends laterally between left and right sides and (i) the first surface extends between the front surface of the base and the distal end of the swingbolt catch and is adjacent to, and joined through a first transition region with, the front surface of the base and (ii) the second surface extends between the rear surface of the base and the distal end of the swingbolt catch and is joined, through a second transition region, with the rear surface of the base.
