Preferably, each coaxial wire is symmetrical arranged two cable fixed seats.

Preferably, the cross section of the cable fixed seat is U-shaped construction, and it is integrally formed with combiner cavity.

Preferably, the wave filter is set as two, respectively first filter, second filter；The coaxial cable Line is set as three, is connect respectively with the input terminal of first filter, the input terminal of second filter, public resonant column.

Preferably, the antenna combiner further includes one or two cable Line attaching clamp, combiner cavity both ends are respectively set An ear is put, after triaxial cable line is bent to an ear, cable Line attaching clamp is used to triaxial cable line being fixed on the ear In portion.

Preferably, input terminal of the inner conductor layer of the coaxial wire through copper wire and first filter, second filter Input terminal, public resonant column connection.

Using the above scheme, the beneficial effects of the utility model are：

1) by processing cable fixed seat on the joint face of combiner cavity and coaxial wire, by coaxial cable Line is directly welded with combiner cavity using high-frequency welder with Pb-free solder, is improved coaxial wire and is connect with combiner cavity Reliability；

2) combiner cavity and coaxial wire is made to melt for an entirety by scolding tin welding, not only connects and more securely and weld Contact resistance is small, loss is low；

3) cable fixed seat rheo-die-casting can be molded in combiner cavity die casting, reduced installation conventional radio frequency and connected The processes such as punching, tapping when connecing device.
