To provide an installation structure and an installation method of a communication equipment to reduce a number of components of the equipment and make the installation work easy. A communication equipment and an installation structure of the communication equipment to be installed, e.g., outdoors is provided. A handle for carrying the communication equipment also serves as a fixation component of the communication equipment. A method for installation of a communication equipment comprises providing an inclined portion formed at a part of bottom surface of a communication equipment and keeping the communication equipment in a forward-inclined position temporarily with the assistance of the inclined shape portion when the communication equipment is set on a fixation mount to fix the communication equipment preparatory to installation.

Installation structure of (outdoor) communication equipment and installation method thereof

A coaxially connected structure for opposed wiring substrates of the present invention includes a first substrate equipped with a tab type bracket and a second substrate equipped with a socket type bracket, and further includes first and second ground cases respectively mounted on the first and second substrates to cover them. The first and second ground cases are respectively provided with first and second penetration openings to pass the tab type bracket and the socket type bracket therethrough. Exposed parts of the tab type bracket and the socket type bracket from the openings are mutually engaged and being fully surrounded with at least one conductive tubular member which has a function to determine a distance between the first substrate and the second substrate.

Coaxially connected structure for opposed wiring substances and device having the same

A coaxial connector connecting structure according to the invention includes a coaxial connector provided on an outer surface of a housing accommodating a module case of a high-frequency circuit. The module case has a thick side wall with a first through-hole to provide a coaxial space forming portion as a pipe structure so as to be separated from the housing.

A satellite system antenna/high frequency unit of a mobile terminal of the present invention is constructed with a satellite system antenna for a mobile satellite communication system and a satellite system high frequency circuit and a first interface is provided externally of a casing of the unit. A ground system antenna/high frequency unit is constructed with a ground system antenna for a mobile ground communication system and a ground system high frequency circuit and a second interface is provided externally of a casing of the unit. A radio control unit includes a circuit portion within a casing thereof for demodulating a receiving signal to an input intermediate frequency signal and modulating a transmission signal and converting it into an intermediate frequency signal. The radio control unit further includes a radio control interface and a set of switches provided externally of the casing and, in use, only one of the first and second interfaces is connected to the radio control interface. The present mobile equipment can be used in an area which is not covered by a satellite by using a relay device for converting the mobile satellite system into the mobile ground system.
