In the protective cover.
Specifically, first radiator 23 is hollow-core construction, the top of first radiator 23 is cylindrical, lower part
In inverted cone-shaped；Second radiator 25 is hollow-core construction, second radiator 25 in coniform, coaxial cable 22 it is interior
Core wire welds together with the first radiator 23, and the outer core wire of coaxial cable 22 welds together with the second radiator 25.It is described
The thickness of first radiator 23 and second radiator 25 is preferably 1mm-1.2mm.The antenna house 24 and the chassis 26
Thickness be preferably 0.9mm-1.1mm.The design of the utility model can be such that antenna is easily installed on hard ceiling, and this reality
There is no solder shorts line piece, voltage standing wave ratio can be by adjusting the first radiator and the second radiator with the antenna of novel offer
Inclination angle improve, which improve the out-of-roundness of antenna.Simultaneously as using nonmetallic chassis, can effectively improve
The third order intermodulation index of all-around top absorbing antenna.
Specifically, the utility model provides two kinds of non-metal bottom dish structures.
The structure on the first nonmetallic chassis is as shown in Figure 5, wherein the circle centre position on nonmetallic chassis is provided with internal thread sky
Heart cylinder 27, the internal thread hollow cylinder 27 are made of ABS or UPVC materials.This nonmetallic chassis has processing
Lower-cost advantage.
The structure on second of nonmetallic chassis is added as shown in fig. 6, being equivalent on the basis of the first nonmetallic chassis
Metal insert.Specifically, there are one internal thread hollow cylinder 27, the internal threads for the circle centre position setting on nonmetallic chassis
Hollow cylinder 27 has been embedded in a metal insert 28.The height of the metal insert 28 is than the internal thread open circles
The height of cylinder 27 wants low；And the inner wall of the metal insert 28 is tapped, outer wall centre position carries annular slot.Institute
Metal insert is stated preferably to be made of brass.Also, this nonmetallic chassis can mold single injection-molded, have processing side
Just the advantages of.Second of nonmetallic chassis is due to the use of metal insert so that the screw thread service life extends, even if installing day repeatedly
Line will not rivet on the ceiling.
