Technical Field

[0001] The utility model relates to the technical field of combiners, in particular to a waveguide combiner for television transmitting antennas which is easy to install. Background Art

[0002] A TV transmitting antenna waveguide combiner is a device used to connect multiple TV transmitters to a shared antenna. It uses waveguide technology to combine signals of different frequencies so that multiple transmitters can share the same antenna for broadcasting. In a waveguide combiner, the signal on each input port is transmitted through the corresponding waveguide path, and then meets and combines into an output signal inside the combiner. The output signal contains the signals on all input ports and can maintain frequency isolation to avoid interference.

[0003] The existing television transmitting antenna waveguide combiner is composed of a base and a shell cover, and the base and the shell cover are fixed by means of multiple bolts. Although this method can achieve fixed installation of the base and the shell cover, auxiliary tools such as screwdrivers are needed to screw the bolts during the installation process, which is very troublesome and inconvenient to quickly install the base and shell cover of the television transmitting antenna waveguide combiner. Therefore, we propose a television transmitting antenna waveguide combiner that is easy to install to solve the above problems. Utility Model Content
