Summary of the invention

The purpose of this utility model is exactly the deficiency in order to solve prior art and a kind of compact conformation of providing, reliable is made assembling simple, is convenient to the overhead antenna of producing.

The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of overhead antenna, it is characterized in that, it comprises outer cover, antenna base, is provided with AM/FM Anneta module, navigation module and amplifier module that radio signal receives, AM/FM Anneta module is by being connected as a whole with amplifier module Tenon, and be fixed on antenna base, by screw lock, radio signal is just transferred in amplifier and amplifies thus like this, improve signal quality, the loss of compensation output line, then output on equipment by cable; Navigation module is fixed on antenna base, is screwed, and outgoing cable output, the other end of cable and equipment connection, after satellite communication signal receives by navigation module and amplifies, be passed on equipment by cable.

As further illustrating of such scheme, AM/FM Anneta module adopts blade antenna, at least two functions in the integrated amplitude modulation/frequency modulation of this antenna (AM/FM) broadcast, mobile digital TV broadcast (CMMB, DVB), satellite navigation (GPS, the Big Dipper, GLONASS), mobile communication (CDMA/GSM/DCS/PCS/WCDMA/TD-SCDMA/TD-LTE/FDD-LTE), WIFI, in the bottom of blade antenna, one side is provided with recess, and navigation module is arranged on the below of recess.

Described navigation module surface printing has many wire, receives for radio signal, has at least two tenons, the tongue-and-groove that amplifier module setting is corresponding with described tenon and tongue-and-groove hole in the bottom of AM/FM Anneta module.

Between described adjacent two tenons, be provided with recess, between the bottom of this recess and amplifier module surface, there is certain interval.

The both sides with amplifier module are set up in described tongue-and-groove and tongue-and-groove hole separately, make together with AM/FM Anneta module can be fixed on mortise by the tongue-and-groove of amplifier with amplifier module, to form an entirety, then welded by cable and the amplifier module of cable output end.

Described amplifier module is provided with at least two location holes, two installation screw holes, is provided with location hole and the support column that screw hole is corresponding is installed on base, and the entirety of AM/FM Anneta module and amplifier composition is anchored on base.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

The utility model adopts AM/FM Anneta module, navigation module and amplifier is co-located on same base, by cable, signal is passed on equipment, not only can greatly reduce amplifying antenna volume, reduces antenna cost of manufacture; In the environment being used in combination at several antennas, compact structure letter can reduce blocking between AM/FM antenna and antenna, amplifying circuit and AM/FM antenna simultaneously, and the electrical property each other of avoiding at the bottom of maximum limit affects.
