Most of the above functions require an antenna to receive signals/transmit information, and will not work without an antenna device
[0003] At present, the function of the traditional antenna is single, and the more electronic equipment, the more antennas are needed. It is extremely inconvenient to install multiple antennas on cars and boats with limited space, and the installation position of the antenna is also very important. 1.

Embodiment Construction

[0013] Referring to accompanying drawings 1-3, the shark-fin antenna structure has an antenna housing 1, and the antenna housing 1 is configured as a shark-fin streamlined housing. A radio receiving antenna is arranged on the inside upper part of the antenna housing 1, and the radio receiving antenna can adopt a helical spring antenna, a metal antenna or the like. One end of the radio receiving antenna is provided with an antenna signal output end, and the antenna signal output end is connected with the signal input end of the antenna amplifier through the antenna connection element, or directly connected with the coaxial cable.

[0014] Antenna shell bottom is equipped with installation base plate 2, and installation base plate 2 is provided with antenna fixing screw rod 3, fixing nut 4, or other fixing parts, can be fixed on car, boat top and car, relevant position of boat outside with shark fin antenna.

Abstract

The invention of shark fins antenna relates to a radio receiver antenna for vehicle and marine, especially for AM/FM, GSM, GPS, and ETV. The structure has the antenna shell. The upper of shell inner sets a radio receiver antenna. One side of the antenna sets the output end of antenna signals. The output end connects the component and the signal input end of antenna amplifier through the antenna, or matching connects the coaxial cable directly. The antennas shell bottom installs the floor. The type of shell sets to be the shark fins. The radio receiver antenna uses the spiral spring antenna or metal antenna. The installed floor sets up the antenna fixed screw and nut. The floor can be installed with AM/FM antenna amplifiers, GPS receiver, GSM receiver, and ETV receivers.

Description

technical field [0001] What the shark fin type antenna of the present invention relates to is a kind of radio signal receiving antenna used for cars and boats, especially for radio broadcasting (AM / FM), radio communication (GSM), satellite navigation (GPS), vehicle-mounted television (ETV) for receiving device. Background technique [0002] With the rapid development of electronic technology in cars and boats today, listening to radio (FM / AM) and CD music can no longer meet the needs of car and boat owners. Entertainment and office systems are already a necessary configuration for high-end cars and boats, and they are also the direction of electronic development for cars and boats. Most of the above functions require an antenna to receive signals / transmit information, and will not work without an antenna device. [0003] At present, the function of the traditional antenna is single, and the more electronic equipment, the more antennas are needed. It is extremely inconvenie...
