Embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

At first, see also shown in Figure 1, it is three-dimensional exploded view of the present utility model, it mainly is by base plate 20, copper sheet 21, L shaped iron plate 22, loam cake 23 and bottom 230 are formed, the front and back side of described base plate 20 all is brushed with copper sheet 21, and make painstakingly Xing Cheng Swastika word moulding of copper sheet 21, and can receive the signal of UHF, then an outside copper sheet 210 has been extended upward L shaped iron plate 22, and make L shaped iron plate 22 have a suitable spacing 220 with base plate 20, be provided with a grume 3 again in the bottom of L shaped iron plate 22, and can utilize grume 3 with the L shaped iron plate 22 cemented base plates 20 that schedule, and make L shaped iron plate 22 and base plate 20 keep suitable spacing 220, and be provided with L shaped iron plate 22 (not shown) equally on the corresponding end limit of L shaped iron plate 22, so that receive the signal of VHF, the base plate 20 after will assembling at last, copper sheet 21 and L shaped iron plate 22 are placed on bottom 230, and utilize screw 4 that loam cake 23 and bottom 230 are screwed togather locking and form domestic aerial 2 (as shown in Figure 2).

Secondly, see also shown in Figure 3, schematic diagram is arranged in the front that is the utility model copper sheet and L shaped iron plate, described base plate 20 front sides are brushed with copper sheet 21, and make painstakingly Xing Cheng Swastika word moulding of copper sheet 21, and the signal of the comprehensive reception UHF of energy, and need not install the IC plate, so do not need plug-in comparatively convenient when using, and can reduce cost of manufacture, be positioned at an outside copper sheet 210 and extended upward L shaped iron plate 22, and described L shaped iron plate 22 has a suitable spacing 220 with base plate 20, and be provided with a grume 3 in the bottom of L shaped iron plate 22, can L shaped iron plate 22 is cemented with base plate 20, make L shaped iron plate 22 and base plate 20 keep suitable spacing 220 simultaneously, and the comprehensive signal that receives VHF of energy, be not subjected to the restriction of angle fully, quite practical and convenient.
