FM radio transmitting antenna with easy installation

Abstract

The invention discloses an FM radio transmitting antenna with easy installation. The FM radio transmitting antenna comprises a connection crossbar. An outer surface of the connection crossbar is sleeved with a fixed sleeve tube. An inner surface of the fixed sleeve tube is covered with a soft rubber gasket, and two sides of the fixed sleeve tube are symmetrically connected to fastening pins. A transmitting antenna is fixed on an upper surface of the connection crossbar, and a power supply line tube is fixed to one side of a lower surface of the connection crossbar. A cushion block is fixed toan outer surface wall of one side of a connection longitudinal rod, and a buckle is fastened on an outer side of the cushion block. An insulating rod is clamped to the bottom of the connection longitudinal rod, lower clamping plates are symmetrically welded to two sides of an upper end outer surface wall of the insulating rod, and upper clamping plates are symmetrically welded to two sides of a lower end outer surface wall of the connection longitudinal rod. The upper clamping plates and the lower clamping plates are in a snap fit through fixed pins. The upper clamping plates are internally provided with through holes. The FM radio transmitting antenna has the advantages of simple and reasonable overall structural design, stable sealing of joints, flexible and convenient installation and disassembly operations and high practicability.

Description

technical field [0001] The invention relates to the technical field of digital equipment, in particular to an FM radio transmitting antenna which is easy to install. Background technique [0002] An antenna is a transformer that converts the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, used in radio equipment to transmit or receive electromagnetic waves Components, engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all use electromagnetic waves to transmit information, all rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal Antennas are also required for energy radiation. Generally, antennas are reversible, and the basic characteristic parameters of the same antenna for transmission or reception are the sam...

AI Technical Summary

Problems solved by technology

[0003] However, there are some deficiencies in the existing FM radio transmitting antenna during use. The connection of the antenna is not sufficiently sealed and stable, and the installation and disassembly operation is not flexible enough, which reduces the practicability of the antenna.
