Description

Technical Field

[0001] This utility model relates to the field of broadcast transmitting antenna structure technology, and in particular to a broadcast transmitting antenna that is easy to adjust. Background Technology

[0002] Broadcast transmitting antennas play a crucial role in radio and television stations. Their main function is to load modulated audio or video current onto a higher-frequency radio frequency current, which is then transmitted through the antenna to form electromagnetic waves. This allows the waves to be transmitted over greater distances and received by a wider audience. Adjustable broadcast transmitting antennas typically refer to the antennas used in mobile transmission systems for vehicle-mounted FM radio stations. These antennas possess features and advantages such as adjustable frequency and power. They are specifically designed for vehicle-mounted FM radio signal transmission and adopt a multi-functional integrated design concept to meet the requirements of various vehicle-mounted wireless broadcasting, vehicle-mounted audio guides, and other applications.

In current technology, vehicle-mounted radio transmitting antennas are installed using bolts and suction cups, and the length of the antenna is fixed. This type of vehicle-mounted radio transmitting antenna has several problems when used. First, it is easy to damage the antenna due to excessive force when installing or removing it using the suction cup. Second, the antenna length cannot be adjusted or extended to adjust the signal reception capability. Utility Model Content
