Abstract The utility model provides a novel combined UHF antenna, comprising an antenna pedestal, a rod-shaped main antenna body and a rod-shaped auxiliary antenna body. The main antenna body is disposed on the antenna pedestal and has a top end detachably connected to the auxiliary antenna body. A feeder passage allowing a feeder to pass therethrough is provided in the antenna pedestal such that the feeder is electrically connected to a feed point of the main antenna body through the feeder passage. The main antenna body may only be used in a place where antenna signals are powerful, whereas in a place where antenna signals are weak, the auxiliary antenna body may be directly connected to the main antenna body to achieve antenna gain enhancement. The novel combined UHF antenna meets the requirements of high and low gains in service environments, and also is convenient for a user to carry, install and maintain. Fig. 4 Fig. 5 |
