Description
Technical field
The utility model relates to wireless communication technology field, particularly a kind of Frequency Adjustable transmitting antenna.
Background technology
Along with developing rapidly of China's FM broadcasting cause, to antenna require increasingly high; In general, if overlap frequency modulation program shared one secondary transmitting antenna, practiced thrift cost so more; But because the program wave band of each channel is different; Can cause like this because frequency is different, the distance of the signal transmission of launching is very limited, the as easy as rolling off a log loss that causes signal; If, just need change a secondary transmitting antenna in order to guarantee signal emission accuracy; In traditional antenna, owing to be antenna made of iron, be installed in the corrosion easily of outdoor back, lost precision; So use, increased the operation easier of regulating frequency, moreover improved the cost that uses.
Therefore, provide a kind of frequency modulation convenient, lightly attractive in appearance, it is one of these those skilled in the art problem that should address that installation and maintenance are easy to a kind of Frequency Adjustable transmitting antenna.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of frequency modulation convenient, and lightly attractive in appearance, installation and maintenance are easy to a kind of Frequency Adjustable transmitting antenna.
The utility model solves the technical scheme that its technical problem adopted: a kind of Frequency Adjustable transmitting antenna; Form by antenna body and tunable antenna; Wherein: the T-shaped structure of described antenna body has the port that connects transmitter, the T junction that the useful screw in top is fixing in the antenna body lower end; Described port through electric wire pass antenna body inner be fixed in T shape head in conduction frequency modulation contact be connected, said T junction is useful on the screw of stationary adjustable frequency antenna; Said tunable antenna is a telescopic mounting.
Further improvement as the utility model: described tunable antenna is connected with slip frequency modulation bar fit by fixed lever; Be carved with the scale that is used for the regulating frequency wave band on the said fixed lever, fixed lever one end has metallic conductor, on the said metallic conductor fixed screw is arranged; The end that described slip frequency modulation bar is connected with fixed lever is with the scalable fixture.
Further improvement as the utility model: said Frequency Adjustable transmitting antenna can adopt the aluminum alloy materials manufacturing.
Further improvement as the utility model: the antenna body of said Frequency Adjustable transmitting antenna is fixed through ∏ shape fixture and U-shaped set bolt and extraneous supporter.
Compared with prior art; The beneficial effect of the utility model is: after using a kind of Frequency Adjustable transmitting antenna of the utility model; At first only need to regulate tunable antenna, just can reach the purpose of frequency modulation, but tranmitting frequency is high, efficient is high, transmitting boundary is wide; Easy to operate simple, can reduce running cost; Secondly sound construction, light and handy can guarantee in the meteorological condition rugged environment, to work, and is not easy corrosion.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to Fig. 1; A kind of Frequency Adjustable transmitting antenna is made up of antenna body and tunable antenna, wherein: described antenna body 1 T-shaped structure; The port 3 that connects transmitter is arranged in antenna body 1 lower end; The T junction 2 that the useful screw in top is fixing, described port 3 through electric wire pass antenna body 1 inner be fixed in T shape head in conduction frequency modulation contact 4 be connected, said T junction 2 is useful on the screw of stationary adjustable frequency antenna; Said tunable antenna is a telescopic mounting.
Described tunable antenna is connected with slip frequency modulation bar 6 fits by fixed lever 5; Be carved with the scale 7 that is used for the regulating frequency wave band on the said fixed lever 5, fixed lever 5 one ends have metallic conductor, on the said metallic conductor fixed screw are arranged; The end that described slip frequency modulation bar 6 is connected with fixed lever 5 is with scalable fixture 8.
Said Frequency Adjustable transmitting antenna can adopt the aluminum alloy materials manufacturing.
The antenna body 1 of said Frequency Adjustable transmitting antenna is fixed with extraneous supporter through ∏ shape fixture 9 and U-shaped set bolt 10.
Use principle is following:
With ∏ shape fixture 9 and U-shaped set bolt 10 antenna body 1 is fixed in the required place that transmits; There is an end of metallic conductor to insert in the T junction 2 tunable antenna; Screw with the screw on the metallic conductor passes on the T junction 2 is fixed assembling; After the installation, the port 3 through antenna body 1 lower end connects the transmitter that is used to transmit; When transmitting, carry out frequency adjustment if desired, earlier the scalable fixture 8 on the slip frequency modulation bar 6 is unclamped; Then slip frequency modulation bar 6 is moved on the corresponding scale 7 of the required wave band that is adjusted to; Tighten with scalable fixture 8 and fix, so, adjusting finishes.
In sum; After those of ordinary skill in the art reads the utility model file; Need not creative mental labour according to the technical scheme of the utility model and technical conceive and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
