Abstract
The utility model relates to a receiving position indicator of a multipath microwave distributing system. The receiving position indicator includes a tester, an elevating antenna mast, a pedestal tray, and a receiving antenna. One end of the elevating antenna mast is connected with the pedestal tray, and the other end is connected with the receiving antenna. The tester is connected with the receiving antenna. The tester includes a signal display screen. The elevating antenna mast is rotatably connected with the pedestal tray. The receiving antenna is a flat receiving antenna or a Yagi-Uda receiving antenna. The receiving position indicator can satisfy the development demand of better operation of a countryside MMDS digital television. The receiving position indicator adopts the light flat or Yagi-Uda receiving antenna and the hollow elevating antenna mast. The elevating antenna mast is a flexible buckle supporting rod, so the transportation is convenient. The pedestal tray is added with a rotating device, so the rotation problem of the receiving antenna is solved, and the orientation of an MMDS signal is easy to confirm. The MMDS signal is input to the tester, so the intensity of the signal can be displayed conveniently and visually.

Technical field
The present invention relates to broadcasting and communication technique field, particularly Multichannel Microwave Distribution System receives position indicator.
Background technology
The Full Name in English of MMDS is Multichannel Microwave Distribution System, and Chinese implication is Multichannel Microwave Distribution System.It is a kind of wireless communication technique of a kind of optional method that is used for broadband network or receives as the cable TV program.
At present test MMDS microwave signal not simply, method easily; By employing reach 4～5 meters rod and do the reflector net of 1 meter of support bar, bore, the reception antenna that frequency demultiplier is formed, connect the subscriber computer top box and locate the reception signal, because Module of aerial is long; Not only be inconvenient to transport; And have Module of aerial shift position, direction of rotation detection signal power in arms, and process is also loaded down with trivial details, and the signal that STB receives is also inaccurate.
The utility model content
The purpose of the utility model is to design a kind of novel Multichannel Microwave Distribution System and receives position indicator, overcomes above-mentioned shortcoming of the prior art, addresses the above problem.
To achieve these goals, the technical scheme of the utility model employing is following:
A kind of Multichannel Microwave Distribution System receives position indicator; Comprise tester, liftable mast, base disk and reception antenna; One end of said liftable mast connects on the said base disk; The other end of said liftable mast connects said reception antenna, and said tester is connected with said reception antenna.
Said tester comprises signal display.
Be rotationally connected between said liftable mast and the said base disk.
Said base disk is provided with rotating shaft, and said liftable mast is fixed in the said rotating shaft.
Said liftable mast comprises upper boom, king-rod and lower beam; Said king-rod and said lower beam are the tubular rod of hollow; Said upper boom is slidingly located in the said king-rod, and said king-rod is slidingly located in the said lower beam, between said upper boom and the said king-rod, be provided with fixedly buckle between said king-rod and the said lower beam; Said lower beam is fixed on the said base disk, and the top of said upper boom connects said reception antenna.
Said upper boom also is the tubular rod of hollow; The connecting line of said tester is stretched into by the bottom of said liftable mast in the tube chamber of said lower beam, is connected said reception antenna through stretching out from the top of said upper boom behind the tube chamber of the tube chamber of said king-rod and said upper boom successively.
The maximum extension length of said liftable antenna is 5m.
Said reception antenna is dull and stereotyped reception antenna or Yagi spark gap reception antenna.
The beneficial effect of the utility model is following:
1, the utility model can satisfy the better growth requirement of operation of rural area MMDS DTV.
2, the utility model adopts the light flat board or the liftable mast of Yagi spark gap reception antenna and hollow, and the liftable mast is telescopic buckle pole, is convenient to transportation problem.
3, the utility model installs whirligig additional on base disk, solves the rotation of reception antenna, to confirm MMDS aspect easily.
4, the utility model MMDS signal inserts tester, the power of shows signal intuitively and easily.
5, the utility model is simple in structure, and is cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural diagrams intention of the specific embodiment of the utility model.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Multichannel Microwave Distribution System as shown in Figure 1 receives position indicator, comprises tester 1, liftable mast, base disk 2 and reception antenna 3, and said tester 1 comprises the signal display that can read signal strength signal intensity; Said liftable mast comprises upper boom 4, king-rod 5 and lower beam 6; Said king-rod 5 is the tubular rod of hollow with said lower beam 6, and said upper boom 4 is slidingly located in the said king-rod 5, and said king-rod 5 is slidingly located in the said lower beam 6; Between said upper boom 4 and the said king-rod 5, be provided with fixedly buckle 7 between said king-rod 5 and the said lower beam 6; Said base disk 2 is provided with rotating shaft 8, and said lower beam 6 is fixed in the said rotating shaft 8, and the top of said upper boom 4 connects said reception antenna 3; Said upper boom 4 also is the tubular rod of hollow; The connecting line of said tester 1 is stretched into by the bottom of said liftable mast in the tube chamber of said lower beam 6, is connected said reception antenna 3 through stretching out from the top of said upper boom 4 behind the tube chamber of the tube chamber of said king-rod 5 and said upper boom 4 successively; The maximum extension length of said liftable antenna is 5m, and said reception antenna 3 is dull and stereotyped reception antenna or Yagi spark gap reception antenna.
