Abstract: Apparatus having an integral coaxial antenna coupled via a coaxial connector to its internal circuitry has a coaxial switch/connector for alternatively coupling an external coaxial signal source to the internal circuitry, thus reducing impedance mismatch to a minimum with no impedance matching network required.

Abstract: A carrying device for an elongated portable article has a back plate with an integral portion forming a loop for receiving the article, with a stop surface adapted to be engaged by a ledge on the article. The device includes a latch secured to the back plate having a projection cooperating with a part of the article to hold the article in the device. The device can be adapted to carry a portable radio having controls on the top and side and a grille at the front, with the ledge being below the side control. The controls and the speaker grille are not obstructed when the radio is being carried. The device can be used to carry radios which vary in length and in other respects, which are of a size to be positioned within the loop and which have a ledge and a part at a fixed position with respect to the ledge to cooperate with the latch. A belt loop or other mounting element can be attached to the device for supporting the same.

Abstract: An improved subminiature electrical connector arrangement especially suited for miniature electrical or electronic apparatus. The connector arrangement includes a two-piece female connector assembly wherein one part thereof may be suitably interconnected to the circuitry of the apparatus while the same is outside the associated housing. This connector may then be placed in alignment with an opening within the housing and a second connector portion inserts within the opening and makes a snap-fit, weather tight seal therein and engages said first connector portion, all without special tools or any additional hardware. An associated male connector plug makes a convenient interconnection with the female assembly by including a hook-like projection overhanging one edge thereof and which engages a recess in the top of a housing to permit the male plug to rotate downwardly and inwardly into correct mechanical and electrical engagement with the female connector assembly.
