Description

The utility model relates to antenna technology, namely to broadband antennas of the meter and decimeter wavelength ranges with the possibility of combining and creating antennas of different sizes and purposes, it is intended for use as receiving and transmitting radio-television antennas for broadcasting and transmitting multi-program radio and television centers, including digital television programs.

Closest to the technical nature of the proposed one is a radio-television transceiver antenna containing a vibrator in the form of two triangular frames located in the same plane. The coaxial cable is inserted at the point of zero potential and laid either inside the tubes of the canvas or on the mast from the opposite side. The cable sheath is soldered to one tube, and the central core to the opposite one (All about antennas. Handbook. Moscow, Onyx Publishing House, 2008, pp. 80-81).

A disadvantage of the known antenna is the inconvenience of laying and connecting the cable, the inability to close the cable connection from the rain, the inability to install an amplifier. Another disadvantage of the known antenna is the insufficient quality of signal reception and transmission, as well as the inability to receive meter and decimeter waves simultaneously from channel 1 to 60.

The objective of the utility model is the creation of a radio-television transceiver antenna that provides the convenience of laying and connecting a coaxial cable, and high-quality reception and transmission of radio-television frequency signals.

The problem is solved in that in a radio-television transceiver antenna containing a vibrator, including at least a pair located in the same plane and interconnected open frames and output terminals located next to each other, one of which is the positive terminal of the antenna, and the second her negative conclusion

an additional half-vibrator connected parallel to and adjacent to the opposite side of the frame to the point of attachment of the vibrator and equipped with an output terminal, which is the positive terminal of the antenna, is connected to one of the frame connection points.

In addition, the antenna is equipped with a reflector. In addition, the reflector and frames are provided with plates for fastening by means of rods with a threaded connection at the ends. In addition, the frames are triangular.

In addition, the triangular frames have a rectangular or rounded portion at the base.

In addition, the antenna is equipped with rod vibrators of decimeter range or meter range.

In addition, additional rods are attached to the rod vibrators of the decimeter range to receive and transmit signals of the meter range.

In addition, additional rods are attached to the rod vibrators of the meter range for better reception of the meter range.

In addition, the output terminal of the half-vibrator can be used to connect to the central core of the coaxial cable or soldered to the central terminal of the connector-F, the housing of which is fixed with a nut.

In addition, the antenna can be equipped with an amplifier connected to the output terminals.

In addition, the antenna has a universal stand for mounting the antenna in the hole on the TV and for installation on a flat surface.

The implementation of the radio-television transmit-receive antenna in this way provides the convenience of laying and connecting a coaxial cable, since the laying and connection occurs at the bottom of the vibrator, and any other structural elements do not interfere with the installation and connection operations, and it becomes possible to install, if necessary, the amplifier and cover it with a plastic box from rain or solder and fasten the connector-F connector. In addition, the supply of the antenna with an additional half-vibrator contributes to the amplification of the signal, which improves the quality of the transceiver of radio and television frequencies. The presence of a rectangular or rounded section at the base of each triangular frame allows you to increase the internal capacitance of a triangular vibrator, which leads to an increase in the amplification of the radio and television signal without significantly increasing dimensions, such as a zigzag two-square antenna. Equipping the antenna with a reflector improves the gain characteristics of the antenna.

The implementation of the antenna in this way also allows you to design antennas for various purposes and sizes, providing high-quality reception and transmission

radio television frequencies with a high coefficient of performance (KPD) while reducing overall dimensions.

The proposed radio television antenna allows you to receive or transmit meter waves from channel 1 to 12 and decimeter waves from 21 to 60 channels simultaneously without matching devices. The fastening of the reflector to the frames by means of rods with a threaded connection makes it possible to disassemble the antenna for its compact packaging during transportation.
